Production Description
HS Code:3902100090
Polypropylene is a polymer formed by addition polymerization of
propylene. It is a white waxy material with a transparent and light
appearance. The chemical formula is (C3H6)n, the density is
0.89~0.91g/cm3, It is flammable, with a melting point of 189ºC,
softening at about 155ºC, and the use temperature range is
-30~140ºC . It is resistant to corrosion by acids, alkalis, salt
solutions and a variety of organic solvents below 80°C, and can be
decomposed under high temperature and oxidation.
Key Advantages Over Standard PP
Tailored performance for niche applications.
Cost-effective alternative to engineering plastics like ABS or
nylon.
Retains PP’s inherent benefits (lightweight, chemical resistance)
while addressing weaknesses.
Product application in LED light field
Product application in Switch and Socket
Product application in Toilet-Seat
