- Excellent thermal conductivity – perfect for LED housings and high-heat applications
- Built-in flame retardancy and smoke suppression
- Superior dispersion, whiteness and tinting strength
- Fully REACH-compliant, heavy metal-free, environmentally preferred
Applications
- Engineering plastics (PA, PBT, PC, PPS),
- Coatings & paints,
- Glass-fiber reinforced compounds,
- Rubber, friction materials, ceramics and high-performance composites.
Why Sintah Chemicals ZnS?
Produced via proprietary high-temperature calcination and multi-stage purification, delivering unmatched purity, weather resistance and batch-to-batch consistency.
SINTAH CHEMICALS delivers high-efficiency, environmentally progressive flame retardants that meet the strictest global standards while improving performance and reducing total formulation cost.
Flagship Product – FR 2000B
A superior alternative to antimony trioxide (Sb₂O₃), combining advanced flame retardancy with significant cost savings. Ideal for ABS, HIPS, PP, PBT, PA, and PVC, it excels as a synergistic additive with unmatched advantages.
Key Advantages
- 100 % Sb₂O₃ replacement – no performance loss
- High whiteness (≥95) – cuts TiO₂ usage and cost
- Stronger flame retardancy + smoke suppression + anti-dripping
- Excellent thermal & color stability
- Particle size 10–20 μm, heavy-metal free, REACH-compliant
- UL94 V-0 achieved at lower loadings
Flame Retardant Portfolio
- Halogen-Free systems – PA6/66, PPA, epoxy, TPE (low smoke, high mechanicals)
- Polyolefin solutions – PP, PE, TPE (synergistic, low smoke, filler-compatible)
- Masterbatches – PA, PBT, PET （50 % Sb₂O₃ reduction in brominated systems)
- PVC specialties – wire & cable, leather, coatings (high CTI, low migration)
Why Sintah Chemicals Flame Retardant?
Proven performance, lower total cost, full regulatory compliance, and expert technical support for custom solutions.
