Yuan jiang card - 99.8% high purity ultra-fine antimony trioxide (environmental protection) 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.Widely used in plastics, rubber, textile, chemical fiber, paint, paint, electronics, sugar, porcelain, ceramic and other industries, as the clear Cleaning agent due to glass manufacturing, can be used as a raw material, the production of metal passivator can also be artificially catalyst used in organic synthesis industry.
Antimony trioxide small encyclopedia:
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.
