High-efficiency phosphorus-based stabilizer offering superior melt stability during high-temperature extrusion and injection molding processes.
Low volatility and excellent thermal stability, minimizing plate-out and die drool in demanding processing conditions.
Synergistic compatibility with calcium-zinc (Ca/Zn) and other non-toxic stabilizer systems for enhanced PVC compound performance.
Reduced discoloration tendency and improved long-term color retention in rigid and flexible PVC formulations.
Free-flowing microprilled solid form ensures excellent dosing accuracy and dispersion in dry-blend compounding.
Rigid PVC profiles for window frames and siding requiring high extrusion stability and surface quality.
PVC pipes and fittings manufactured via twin-screw extrusion under elevated shear and temperature conditions.
Flexible PVC cables and wire insulation where low smoke and halogen-free processing aids are critical.
Medical-grade PVC tubing and packaging films requiring FDA-compliant, non-toxic stabilization solutions.
Recycled PVC compounds where enhanced melt protection mitigates degradation from contaminants and thermal history.
