3. Application
1). It can be used as both a catalyst and a foaming agent in fireproof coatings, and its performance is slightly better than ordinary ammonium polyphosphate.
2). In the application of ethylene vinyl acetate copolymer, if it is used with cyclic urea formaldehyde (cooking agent) in polyolefin, it can show a highly effective expansion and flame retardant effect.
3). The combination of thermoplastic polyester and pentaerythritol phosphate is an effective flame retardant.
4). It is used as flame retardant for polystyrene instead of polybrominated diphenyl ether.
5). It is used as a flame retardant for rubber (butadiene, butyronitrile, polypropylene elasticity).
6). It is used as flame retardant for nylon 6/6, epoxy resin and rigid polyurethane foam.
7). It is used together with porous graphite as a flame retardant for the silicone molding compound body.
4. Packing and Storage
Packing: Double coated plastic woven bag, 25kg net; 500kg / 1000kg jumbo bags.
