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.
