Phosphorus-nitrogen synergistic system enabling excellent flame retardancy without halogenated compounds.
Designed specifically for polyester (PET, PBT) matrices with high compatibility and minimal impact on mechanical properties.
Low smoke density and negligible toxic gas emission during combustion—meets UL 94 V-0 at ≥1.6 mm thickness.
Good thermal stability up to 300 °C, supporting standard melt-processing conditions including extrusion and injection molding.
Non-migrating formulation ensures long-term flame-retardant performance and surface integrity.
Electrical & electronics housings (e.g., connectors, switches, terminal blocks).
Automotive interior components (e.g., trim panels, air ducts, sensor housings).
Textile fibers and spunbond nonwovens requiring flame-resistant PET staple fiber.
3C product enclosures complying with IEC 60695 and RoHS/REACH requirements.
Industrial conveyor belts and technical fabrics where low-smoke, halogen-free performance is mandated.
