Yuanjiang Brand - 98% antimony trioxide is a kind of pure white fine powder. The main crystal structure as cubical shape crystallization, thermal stability, non-toxic, no corrosive gas, flame retardant effect lasting, no molten drop, and stored in the non-volatile, no precipitation, friendly to the environment, significantly improve flame retardant, self-extinguishing, smoke abatement and does not affect the base material of other performance effect.Antimony trioxide is the first application of flame retardant, suitable for epoxy resin, polyurethane, chloroprene rubber, polystyrene, polyvinyl chloride, polyester, etc., when used alone dosage, poor flame retardant effect (unless the flame retardant containing halogen), when with halogen compound (r.h. X) and has a good synergistic effect, when the flame retardant effect is improved obviously.
Reaction emits the H2O and generate low melting point, to gasification halide antimony, ACTS as dilution of combustible gas.His relative density is larger at the same time, covering the air on the polymer surface, can promote the coking reaction, reduce the temperature of the combustion system, to capture the combustion process of gas phase dissociation. HO and h., thus inhibiting burning.Antimony trioxide is actually used widely in flame retardant agent association effect, and the ratio of the halogen compound 3-1 best.
