PRODUCTS
Silicon-based, phosphorus–nitrogen and antimony flame retardants, ATO replacement grades and PVC processing additives — engineered for consistent, compliant performance.
Antimony-based Flame Retardant
HBT001
HBT001 is a high-performance antimony-based flame retardant synergist from the HBT Series, a direct drop-in replacement for conventional antimony trioxide (ATO) in PVC flame-retardant formulations, improving char formation, smoke suppression and processing stability.
Antimony-based Flame Retardant
HBT002
HBT002 is a high-performance antimony-based flame retardant synergist from the HBT Series, a direct drop-in replacement for conventional antimony trioxide (ATO) in PVC flame-retardant formulations, improving char formation, smoke suppression and processing stability.
Silicon Based Flame Retardant
GH-K100
GH-K100 is an efficient halogen-free silicon-based flame retardant. White powder, halogen-free and non-toxic, it can replace 30%–50% of antimony trioxide (Sb2O3 ≥ 99.5%) in equal amounts, widely used in PVC automotive interior leather, sofa leather, Oxford cloth, conveyor belts, PVC flame-retardant film, knife-scratched fabric, tarpaulin and textile coatings.
Silicon Based Flame Retardant
GH-K101
GH-K101 is a highly efficient ceramicized flame retardant, halogen-free and non-toxic. It can replace 30%–50% of antimony trioxide (Sb2O3 ≥ 99.5%) in equal amounts, reducing smoke density and improving heat aging resistance, widely used in PVC cables, rubber and plastic pipes, thermal insulation, PVC flooring and injection molded parts.
Phosphorus-Nitrogen Based Flame Retardant
SY-T008
SY-T008 is a phosphorus-nitrogen, halogen-free, non-toxic and antimony-free flame retardant that can completely replace antimony trioxide (Sb2O3 ≥ 99.5%) in PU solvent-free, PVC leather and microfiber leather applications, reducing costs and smoke density with anti-dripping effect.
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.
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.
