PP resin is a plastic that is coinciden with propylene elements, in the circuit is completely saturated links, so they are very safe for the health of users. However, to use technical plastic, PP plastic has the disadvantage of being soft, poorly impacted. Therefore, the use of additional fluids (such as stone powder, lc powder, fiberglass ,…) will significantly improve the hardness, impact strength, abrasion resistance of the product.
Polypropylene is the product of addition polymerization of propylene. All chemist bonds are sigma, that's why it is very safe for people. However, tobe able to use as technical plastic, there are some disvantages for PP: soft, bad impact resistance. For these reasons, adding filler( CaCo3 powder, Talc powder, glass fiber,…) will improve much of the hardness, the impact resistance off product.
