1.As an efficient flame retardant agent, Antimony trioxide is widely used in automotive plastic components (such as dashboards, cable sheaths, seat materials, etc.), which can significantly reduce the flammability of the materials and enhance vehicle safety, meeting strict fire safety standards (such as UL94, FMVSS 302).
2.As an additive, antimony trioxide for PBT can optimize the fluidity and molding properties of polymer materials (such as PP, PVC, etc.), and is suitable for the production of complex-shaped automotive injection molds, thereby enhancing production efficiency.
Introduction
Antimony trioxide for plastic (Sb₂O₃) is a widely used flame retardant in the automotive industry, where safety and material performance are critical. Due to its ability to enhance fire resistance without significantly compromising mechanical properties, Antimony trioxide for plastic is commonly incorporated into engineering plastics such as polyamide (PA), polybutylene terephthalate (PBT), and ethylene propylene diene monomer (EPDM) rubber. This article explores the role of Antimony trioxide for plastic in these materials and its importance in automotive applications.
1. Antimony Trioxide as a Flame Retardant
Antimony trioxide for plastic acts as a synergist with halogenated flame retardants (e.g., brominated or chlorinated compounds), enhancing their effectiveness. When exposed to heat, antimony trioxide for PA reacts with halogens to form antimony halides, which inhibit combustion by scavenging free radicals and forming a protective char layer.
Key Benefits in Antimony trioxide for plastic Applications:
Improved fire safety – Antimony trioxide for plastic Meets stringent automotive flammability standards (e.g., FMVSS 302).
Thermal stability – Antimony trioxide for plastic Maintains performance under high-temperature conditions.
Low smoke emission – Antimony trioxide for plastic Reduces toxic fumes in case of fire.
2. Applications in Automotive Plastics and Rubber
2.1 antimony trioxide for PA Polyamide – Nylon
PA is widely used in automotive components such as connectors, under-the-hood parts, and electrical housings due to its strength and heat resistance.
Role of antimony trioxide for PA:
Antimony trioxide for PA Enhances flame retardancy in combination with brominated compounds.
Antimony trioxide for PA Maintains mechanical properties (tensile strength, impact resistance).
Antimony trioxide for PA Used in wire harnesses, fuse boxes, and sensor housings where fire safety is crucial.
2.2 antimony trioxide for PBT Polybutylene Terephthalate
PBT is used in electrical components, headlight housings, and ignition systems due to its excellent electrical insulation and dimensional stability.
Role of antimony trioxide for PBT:
Antimony trioxide for PBT Improves flame retardancy while retaining PBT’s high melting point (~225°C).
Antimony trioxide for PBT Ensures compliance with UL94 V-0 and other automotive safety standards.
Antimony trioxide for PBT Commonly found in relays, switches, and fuse components.
2.3 antimony trioxide for EPDM-Ethylene Propylene Diene Monomer Rubber
EPDM is used in seals, gaskets, and cable insulation due to its weather resistance and flexibility.
Role of antimony trioxide for EPDM:
Antimony trioxide for EPDM Provides flame retardancy in wire and cable coatings to prevent fire spread.
Antimony trioxide for EPDM Works synergistically with halogenated additives for low-smoke formulations.
Antimony trioxide for EPDM Ensures durability in high-temperature environments (e.g., engine bay applications).
