Carboxylated styrene-butadiene dispersion Fulatex PD0128 is evaluated in downstream applications where anionic binder stability, filler compatibility and heat-activated crosslinking determine process yield. In each application, machine parameters and compliance limits are referenced to standard methods rather than generic performance claims.
Air-laid and carded high-loft webs for acquisition and distribution layers are saturated with Fulatex PD0128 at dry add-on values between 18% and 26% on a two-roll pad followed by a suction slot that removes excess liquor. A 1200 mm wide saturation line running at 80 m/min uses a 15% solids bath when the fibre matrix contains 20% bicomponent PET/polyethylene sheath-core and 80% viscose. Tensile retention after calendering is tested according to NWSP 110.4.R0 (15) using a 50 mm gauge length and a 100 mm/min jaw speed. Foam finishing is preferred over full immersion when the web basis weight is below 40 g/m² because fibre washout and binder migration can shift the tensile ratio to unacceptable levels. Zinc oxide at 0.5–1.5 phr on binder solids is added only after pre-dispersion in water to avoid coagulum. Drying requires staged can temperatures of 90°C, 120°C and 140°C with final web temperature not exceeding 150°C for more than 30 seconds. End products include hygiene acquisition layers, air-laid tabletop wipes and industrial wiping cloths where wet integrity under repeated insult is specified by the converter.
Automotive interior nonwovens based on polyethylene terephthalate and glass-reinforced needlepunch are immersed in a bath of Fulatex PD0128 diluted to 8–14% solids; wet pick-up after vacuum extraction is held between 90% and 120%. The saturated web is dried on a 90 m tenter with three zones set at 110°C, 135°C and 155°C. When the terminal zone exceeds 160°C by more than 15 seconds, tensile loss and fibre discolouration become measurable in the finished part. Crosslinker response is monitored by comparing the ratio of dry tensile to wet tensile after 1 h water immersion, using ISO 9073-3:2023. OEM fogging specifications reference VDA 278:2016 thermodesorption; suppliers must maintain volatile organic condensate below the OEM limit for the part class. Fulatex PD0128's carboxyl functionality permits reaction with melamine-formaldehyde resin at 1–2 phr on binder solids, but the same chemistry can release free formaldehyde during cure if pH falls below 6.5. End components include headliners, parcel shelves, door trim panels and trunk liners where stiffness and snap-in retention are specified by bending length tested at 41° warp and 45° weft overhang. Line personnel observe that delayed curing in high-humidity sites above 65% RH requires a longer zone 2 dwell or a 5°C increase to reach the same insolubility level.
Tufted residential and automotive carpet styles use Fulatex PD0128 in a pre-coat compound loaded with calcium carbonate between 250 phr and 450 phr on dry latex. The formulated compound is adjusted to 70–78% total solids and a Brookfield RVT viscosity of 8,000–14,000 mPa·s at 20 rpm and 25°C. A puddle coater with doctor blade gap of 0.5–1.2 mm and line speed of 10–25 m/min yields a dry coating weight of 450–900 g/m². Tuft bind is measured by ASTM D1335-20, and dimensional stability is checked against ISO 2551:2020 after conditioning at 23°C and 50% RH for 24 h. When filler is added, the mixture tends to generate shear heat in high-speed dispersers; batch temperature above 40°C can destabilise the anionic dispersion and produce micro-grit visible in the dry film. A cooling jacket or short dwell at 800–1,000 rpm is used to prevent temperature rise above that threshold. Coagulants should not be introduced to the neat latex; pre-diluted ammonium chloride at 0.2–0.5 wt% of compound is added slowly to the filler slurry rather than the binder phase. End products include broadloom carpet, carpet tiles and automotive floor mats where ISO 8543 total pile mass and AATCC 165 crockfastness must be reported to the specifier.

Shoe counter and insole impregnation lines rely on high solids carboxylated SBR to stiffen cellulose board without the brittleness of full acrylic or phenolic binders. A saturating line uses a dip tank with Fulatex PD0128 adjusted to 20–30% solids and wet pick-up of 70–120% on a two-roll nip. The saturated web passes over steam-heated drying cylinders at 90–110°C before hot pressing at 120–140°C and 10–20 bar for 3–5 min. Flexural stiffness of the pressed board is tested in three-point bending according to ISO 178:2019 with a 100 mm span and 10 mm/min loading rate. Zinc oxide at 2–4 phr on binder solids serves as the ionic crosslinker; the pH of the bath must remain between 8.0 and 9.5 because lower pH increases the risk of coalescence on roll edges. Water absorption after 24 h immersion is controlled to below the value set by the footwear board specification, because carboxylated SBR retains less water than water-soluble starch or polyvinyl alcohol binders at equivalent add-on. The end use includes footwear counters, midsoles and heel stiffeners where dimensional recovery after flexing is evaluated by SATRA TM3 or equivalent. When the same dispersion is used with recycled cellulose fibres, wet strength retention improves relative to unmodified SBR; however, the final board can be difficult to slit if over-pressed above 150°C due to thermoset build-up.
Electrostatic flocking on polyester-cotton and polyamide substrates uses Fulatex PD0128 as the primary binder when the finished textile must survive water immersion without tuft release. The compound is coated by knife-over-roll at 0.3–0.6 mm wet film thickness, then flock fibre of 0.6–1.0 mm length is deposited by an AC electrostatic field at 40–60 kV. Curing is performed in a stenter at 140–150°C for 2–3 min; melamine-formaldehyde resin at 1.0–2.0 phr on binder solids accelerates the wet-peel plateau. Peel adhesion is tested to ISO 11339:2022 with a 180° peel angle and 300 mm/min jaw speed on dry and wet specimens after 120 h immersion at 40°C. A polyacrylate alkali-swellable thickener at 0.5–1.5 wt% of compound is added to obtain a Brookfield RVT viscosity of 3,000–6,000 mPa·s at 20 rpm; overdosing causes roping and uneven pick-up. Amine-based pH adjusters should be avoided because they can displace the anionic surfactant shell and initiate microflocculation before the coater reaches steady state. End products include automotive glove boxes, armrest covers, apparel flock transfers and technical brushes where abrasion resistance is also measured by martindale under ISO 12947-2:2016.
Paper and cellulose-fibre gasket base is saturated with Fulatex PD0128 to close interstitial porosity and improve oil retention without incorporating plasticisers. A paper saturator applies the latex at 15–25% solids and a wet pick-up of 60–100% on the dry fibre; the web is dried on afterburner-heated cans at 100–120°C and then calendered at 30–50 N/mm nip load. Tensile energy absorption is measured by TAPPI T 494 om-22; porosity is determined by ISO 5636-5:2013 using the Gurley method. Fulatex PD0128 is selected when the end part requires resistance to short-term oil contact at temperatures up to 120°C. Continuous immersion in hot oil above 150°C or prolonged exposure to aromatic fuel blends is outside the recommended operating range and published data for this specific configuration is limited. The carboxylated binder also improves retention of mineral filler in the sheet, reducing dust generation during die-cutting. End products include cylinder head gasket base, oil filter end-cap paper and transmission separator sheets where burst strength is measured by ISO 2758:2014.

Fulatex PD0128 is supplied as a high-solids anionic aqueous dispersion of a carboxylated styrene-butadiene copolymer. The product designation is positioned for paper and board coating applications in which binding strength, wet-pick resistance, and compatibility with mineral pigment slurries are process-critical. The material is synthetic and polymer-stabilized, not protein-stabilized, and therefore differs from high-ammonia natural rubber latex in allergen profile, ammonia content, and response to cationic additives. Publicly available batch data for this specific model are limited to manufacturer trade literature; consequently, the numerical ranges in this technical introduction are class-typical values for anionic carboxylated styrene-butadiene latex unless identified as PD0128 lot data. A production campaign should not proceed without a lot-specific certificate of analysis and a plant-scale trial using the actual pigment slurry.
In a coating kitchen, Fulatex PD0128 is introduced as a cobinder rather than as a neat film former. The dispersion is added after the pigment slurry has been dispersed and neutralized. Direct addition into an acidic calcium carbonate slurry can produce localized charge reversal and visible agglomerates. The receiving slurry should be held at pH 8.0–9.0 before latex addition. A low-shear side-entering mixer with a tip speed below 1.5 m/s is used, and the latex addition rate should not exceed 2 wt%/min of the final coating colour mass. This limit is not an intrinsic property of the latex but a practical boundary derived from calcium-ion sensitivity and shear-thinning response of filled carboxylated styrene-butadiene coating colours.

The low-shear viscosity range of 100–400 mPa·s does not predict high-shear coating behaviour. High-shear viscosity must be measured on the finished pigmented colour using a capillary or cone-and-plate viscometer. For blade coater conditions above 105 s⁻¹, the apparent viscosity is a system response controlled by pigment packing, dispersant demand, latex particle size, and thickener architecture. Neat latex viscosity is therefore a release criterion, not a runnability specification.
The dispersion remains colloidally stable within a defined pH window. Below pH 5.0, protonation of surface carboxylate groups reduces negative zeta potential and promotes microflocculation in the presence of divalent calcium ions from ground calcium carbonate. For a coating colour containing 60 parts ground calcium carbonate and 40 parts kaolin, a polyacrylate dispersant is added at 0.05–0.15 parts per hundred parts pigment to maintain calcium-ion buffering. The latex is then added under gentle agitation. A high-speed Cowles disperser operating above 10 m/s tip speed should not be used on the pure latex stream because the resulting vortex can entrain air and increase coagulum formation.
For comparable anionic carboxylated styrene-butadiene dispersions, electrophoretic mobility measurements show a zeta potential of −30 to −50 mV at 25°C and ionic strength 10–50 mS/m. Published zeta potential data for Fulatex PD0128 are not available. The practical stability check in production is the mechanical stability test according to ISO 2006-1:2022 together with a filtered coagulum count after circulation through a 100 µm screen. A rising pressure drop across that screen at constant flow indicates destabilization or pigment flocculation rather than a simple viscosity increase.
Fulatex PD0128 differs from high-ammonia natural rubber latex in nitrogen content and allergen profile. It does not rely on ammonia to the same extent; the received dispersion typically contains less than 0.1 wt% ammonia, while high-ammonia natural rubber latex may contain 0.6–0.8 wt%. Compared with polyvinyl acetate homopolymer binders, the carboxylated styrene-butadiene backbone gives higher wet-pick resistance under offset fountain solution contact, but it can be more sensitive to shear-induced destabilization in calcium-rich colours. Compared with oxidized starch co-binders, the latex requires no thermal cooking or enzyme conversion, but it cannot replace all starch when sheet stiffness and bending resistance are the limiting specifications.
In a blade-coated woodfree paper formulation, the practical substitution boundary is set by sheet stiffness, binder migration, and blistering risk rather than by dry pick strength alone. A starting formulation uses 100 parts mineral pigment, 10–12 parts Fulatex PD0128 dry solids, 0.3–0.8 parts cooked starch dry solids, and 0.05–0.20 parts rheology modifier. The finished colour pH is maintained at 8.5–9.5. High-shear viscosity is held at 60–110 mPa·s at 105 s⁻¹. If the coat weight exceeds 12 g/m² per side, the latex substitution is usually kept below 15 parts because higher latex levels can lower air permeability and increase blistering in web offset drying.
Dry pick resistance is measured on an IGT AIC2-5 printability tester with medium-viscosity oil according to ISO 3783. In a mill trial, the runnability limit is not solely the pick value; it is the absence of fibre roughening on the fourth printing unit and the absence of coating build-up on the blanket. Published data for Fulatex PD0128 at specific substitution ratios are limited. The formulation ranges above are initial pilot-coating points, not validated release values for all woodfree grades.
Fulatex PD0128 should be stored in closed stainless steel 316L or lined carbon steel tanks at 5–35°C. Storage below 5°C creates freeze-thaw instability. If a frozen container is received, thawing at 5–25°C under gentle agitation may restore the dispersion only if the particle size distribution remains unimodal; otherwise the lot must be quarantined. At ambient temperatures above 35°C, the tank should be closed or nitrogen-blanketed to reduce surface skin formation. Mild recirculation at 5–10 rpm with a low-shear side-entering mixer prevents settling, but vortex formation must be avoided because entrained air acts as a nucleation site for coagulum.
Microbiological preservation is required in recirculated coating supply systems. An isothiazolinone-based biocide at 0.01–0.05 wt% of the coating colour is typical, but compatibility with the anionic latex must be checked before use. Cationic biocides and cationic wet-strength resins can flocculate the dispersion. The product should not be premixed with alum solution above 0.5 wt% at pH below 5.5. Diaphragm pumps are preferred over progressive cavity pumps when shear-sensitive rheology is observed. In a recirculation loop, a centrifugal supply pump operating at 15–25 Hz and a 100 µm in-line filter are used before the coater head. The filter pressure drop should remain below 0.8 bar; a rising pressure at constant flow indicates destabilization and requires a shut-down for wash-up rather than an increase in pump speed.
High-speed blade and film press applications impose transient shear rates above 106 s⁻¹. Above this threshold, carboxylated styrene-butadiene latices can exhibit shear-induced microflocculation if the pigment dispersion is marginal. The coating kitchen is therefore operated with a deaeration loop. A vacuum deaerator reduces entrained air from 1.0–1.5% to below 0.2% by volume before the colour enters the pressure screen. The pressure screen is fitted with 0.15–0.25 mm slots and is installed downstream of the machine tank; it is not a substitute for pigment screening. Screen reject should be inspected for latex-rich foam, which indicates antifoam incompatibility or excessive high-shear pump loss.
At these speeds, the coat weight is commonly 4–15 g/m² per side. The product is used as part of a co-binder system rather than as the sole binder. The high-shear rheology limit is established on the actual machine because piping geometry, screen size, and blade pressure influence the shear history. Published data for Fulatex PD0128 under production speeds above 1,200 m/min are limited; the described deaeration and screen arrangement is applied to anionic carboxylated styrene-butadiene coating systems to maintain machine cleanliness.

Before production release, the receiving plant should obtain a lot-specific certificate of analysis, a particle-size distribution report if high-shear screen retention is observed, and a regulatory statement for the intended end use. A mill trial with the actual pigment slurry is the only reliable method to set the high-shear viscosity and blade runnability limits for Fulatex PD0128.
