High-purity, halogen-free ammonium polyphosphate (APP) with optimized particle size distribution for excellent dispersion in polymer matrices.
Thermally stable up to 250 °C, enabling compatibility with processing temperatures of engineering thermoplastics such as polypropylene and polyethylene.
Intumescent mode of action: forms a protective char layer upon exposure to heat or flame, significantly reducing heat release and smoke generation.
Low water solubility and high hydrolytic stability, ensuring long-term performance retention in humid or outdoor applications.
REACH-compliant and free of heavy metals, antimony, and halogens—supporting sustainable material design and regulatory compliance.
Polypropylene (PP) compounds for automotive interior parts including dashboards, trim, and seat components.
Low-density and linear low-density polyethylene (LDPE/LLDPE) cables and wire insulation requiring UL 1581 V-0 rating.
Wood-plastic composites (WPC) used in decking, cladding, and outdoor furniture.
Thermoplastic elastomers (TPE) for flexible flame-retarded profiles and seals.
Intumescent coatings and mastics for passive fire protection of structural steel and cables.
