Intumescent char
Forms an insulating foam char that protects the substrate.
Ammonium polyphosphate (앱) is a halogen-free phosphorus–nitrogen flame retardant used in intumescent coatings, 폴리프로필렌, 에폭시, 폴리우레탄, textiles and wood. SUNCHEM supplies APP with a batch COA on every shipment; TDS는 요청 시 전송됩니다..
APP releases phosphoric acid when heated, which chars the polymer, and ammonia, which blows the char into an insulating foam. With a carbon source such as pentaerythritol and a blowing agent such as melamine it forms the classic intumescent system used in fire-protective coatings for steel and wood, and in halogen-free polypropylene.
Long-chain crystal phase II APP has low water solubility and suits plastics and coatings; surface-treated grades further reduce water pick-up. 인, nitrogen, solubility and particle size are the numbers to compare.
Forms an insulating foam char that protects the substrate.
No bromine or chlorine, with low smoke and corrosive gas.
We quote against your phosphorus and nitrogen content, crystal phase, degree of polymerization, water solubility, particle size and moisture and send the batch COA for each lot.
