High temperature resistant PP plastic particles

Polypropylene is a non-toxic, odorless, tasteless, milky white highly crystalline polymer with a density of only 0.90--"0.91g/cm3, which is one of the lightest varieties of all plastics. It is particularly stable to water, with a water absorption rate of only 0.01% and a molecular Polypropylene weight of about 81,150,000. Formability is good, but because of the shrinkage rate (1%~2.5%). Thick wall products are easy to sag, for some parts with high dimensional accuracy, it is difficult to meet the requirements, and the surface of the products is good.Chemical stability The chemical stability of polypropylene is very good, in addition to can be concentrated sulfuric acid, concentrated nitric acid erosion, other chemical agents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic   Polyformaldehyde hydrocarbons and chlorinated hydrocarbons can make polypropylene soften and swelling, while its chemical stability with the increase of crystallinity and improve, so polypropylene is suitable for the production of a variety of chemical pipes and accessories, anti-corrosion effect is good.PC Or ABS
