LF-51L PVC Paste Resin with Low Brookfield Viscosity, Minimal 24-hour Thickening, and Superior Defoaming for Foamed Leather and Toys

LF-51L is medium molecular weight micro-suspension paste PVC resin with average polymerization degree 1300±100. It features stable low Brookfield viscosity, minimal 24-hour paste thickening rate and superior defoaming capacity. The resin delivers delicate, uniform foaming cell structure after chemical foaming, paired with excellent thermal stability to avoid yellowing under high-temperature gelation. It has low impurity particles, high 49μm mesh passing rate and controlled residual VCM, widely applicable to foamed leather, conveyor belts, rotational molding toys, tarpaulins and metal wire coating products.

1. Low & stable plastisol viscosity (4500±2000 mPa·s), good fluidity for coating, casting and foaming processes, no sagging during construction.
2. Ultra-low 24h thickening rate ≤100%, plastisol viscosity stays stable during long-term storage, no sudden thickening to interrupt continuous production.
3. Excellent air release performance, effectively eliminate bubbles, pinholes and surface pits on foamed & coated finished goods.
4. Uniform fine foaming micropores after chemical foaming, soft elastic hand feel, no hole collapse or uneven foaming defects.
5. Great thermal stability and gelation property, finished products maintain clean white tone without severe yellowing after high-temperature baking.
6. Only ≤20 impurity particles, 49μm mesh passing rate ≥99%, reduce surface speckles and coarse particle defects of leather, tarpaulin and toys.
7. Residual VCM ≤10.0μg/g, meets export and general environmental protection standards; low alcohol extract ensures stable compatibility with various stabilizer & filler systems.

• Artificial leather series: Clothing leather, automotive interior leather, floor leather
• Industrial supplies: Conveyor belts, tarpaulin/awning cloth, steel wire coating, bottle cap gaskets
• Toys & casting: Rotational molding soft PVC toys, decorative molded parts

• Standard package: 20kg / 25kg moisture-proof composite kraft paper bag
• Bulk packaging: 500kg / 1000kg flexible ton jumbo bag

Store products in dry, cool and well-ventilated warehouse. Isolate from direct sunlight, high temperature and damp ground. Seal packaging tightly after opening to prevent moisture absorption causing plastisol viscosity fluctuation. Adopt first-in first-out inventory management.

Wear dust-proof mask, rubber protective gloves and chemical safety goggles during feeding and mixing to avoid long-term inhalation of PVC dust. In case of eye contact, flush continuously with plenty of clean water; wash contaminated skin thoroughly with soap and clean water.

All listed technical indicators are factory internal control specifications for reference only, not legally binding acceptance standards. Actual processing performance is affected by plasticizer proportion, stabilizer formula, mixing process and storage environment. Small batch plastisol trial preparation and foaming test before mass production is highly recommended to verify product adaptability.
