Intumescent phosphorus-nitrogen synergistic system enabling efficient char formation under thermal stress.
Halogen-free and low-smoke formulation meeting stringent environmental and safety regulations (e.g., RoHS, REACH).
Excellent thermal stability up to 300 °C, ensuring process compatibility in high-temperature polymer processing.
Good dispersion and compatibility with engineering thermoplastics including polypropylene (PP), polyethylene (PE), and thermoplastic elastomers (TPE).
Low water solubility and hydrolytic stability, supporting long-term performance in humid or outdoor applications.
Flame-retarded polypropylene for automotive interior components (dashboards, trim, battery housings).
Wire and cable jacketing compounds requiring UL 94 V-0 rating and low-corrosivity during combustion.
Electrical enclosures and housings for consumer electronics and industrial equipment.
Building and construction materials including insulation foams and rigid PVC profiles.
Textile back-coatings and technical fabrics for transportation interiors (buses, trains, aircraft).
