PRODUCTS
Silicon-based, phosphorus–nitrogen and antimony flame retardants, ATO replacement grades and PVC processing additives — engineered for consistent, compliant performance.
EPVC Processing Additive
EP-20
EP-20 is a functional EPVC paste-grade processing additive widely used in foamed layers for resilient flooring, foamed leather, anti-slip mats, yoga mats and foamed wallpaper. It replaces 30%–50% of PVC resin, delivering excellent foaming properties, high-speed coating capability and high thermal stability.
EPVC Processing Additive
EP-19
EP-19 is a functional EPVC paste-grade processing additive widely used in PVC conveyor belts, tablecloths, metal coatings and hoses. It replaces 30%–50% of PVC resin, delivering excellent viscosity reduction, scratch and abrasion resistance, and moderate paste viscosity with high sag resistance.
EPVC Processing Additive
EP-17
EP-17 is a functional EPVC paste-grade processing additive widely used in non-foamed and micro-foamed artificial leather and PVC coated tarpaulin. It replaces 30%–50% of PVC resin, improving scratch and abrasion resistance, acid and alkali resistance, and reducing paste viscosity.
SPVC Processing Additive
YA-P19
YA-P19 is a functional PVC processing additive for calendering products (sofa leather, Oxford cloth, plastic flooring, decorative film, raincoat film, electrical tape). It can replace 30%–50% of PVC resin, enhancing processability, melt fluidity and mechanical strength while reducing plasticizer usage.
SPVC Processing Additive
YA-P17B
YA-P17B is a functional PVC processing additive for calendered products, leather and semi-rigid products. It can replace 30%–50% of PVC resin, significantly improving scratch resistance, abrasion resistance and surface smoothness of PVC leather while lowering processing energy consumption.
Quality Assurance
Controlled from source to finished product
Quality is managed across the full chain — from raw material sourcing and R&D formulation through production and final release — so every batch performs the same.
Raw Material Sourcing
Approved suppliers and incoming inspection for every raw material before it reaches the production line.
R&D & Formulation
Flame-retardant formulations developed and validated in our laboratory before scale-up.
Process Control
Key parameters monitored throughout manufacturing for batch-to-batch consistency.
Inspection & Traceability
Each batch is tested and traceable, with documentation aligned to RoHS / REACH compliance.
