4. high compatibility
APP High polymerization crystallization II type ammonium polyphosphate is a water insoluble branched stright-chain polymer and a main branch of Phosphorus-containing inorganic flame retardant . thus this kind of product is of high P and N contents. it has an excellent thermai stability and chemical stability, its water solvent and hygroscopicity is very weak. our prouducts close to neutral and have a low toxcity,has little harm to our body. it is non-volitale and no corrisive gas produced during processing ,high effect ang good safety.
Uses
APP is mainly used in intumescent fire retardant coatings and polyurethane foam, also be used in the flame retardance of fiber, wood and rubber products. With high Molecular Weight (n>1000) and stability, it can be used as the active matter of intumescent flame-retardant thermoplastic, especially for fire retardant PP (UL94-V0) and cable materials.
Applacation range
widely used in intumescent fire retardant caoting,fire retardant building materials , thermal plastic polyolefin and unsaturated aromatic hydrocarbons plastics,polyurethane foam, epoxy resin, cable and rubber ; power devices and fabric.
