PP Plastic

Yongyuan is a professional China PP Plastic manufacturers and suppliers, if you are looking for the best PP Plastic with low price, consult us now! Polypropylene (PP) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials.

Mainly used in the production of various long and short polypropylene fibers, used in the production of polypropylene woven bags, packing bags, injection molding products, etc. for the production of flame-retardant parts for electrical appliances, telecommunications, lighting, lighting equipment and TV sets. PP does not have environmental stress cracking problems. Usually, PP is modified by adding glass fibers, metal additives or thermoplastic rubber. The flow rate MFR of PP ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower elongation strength. For materials with the same MFR, the strength of the copolymer type is higher than that of the homopolymer type. Both the homopolymer type and the copolymer type PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. However, it has no resistance to aromatic hydrocarbon (such as benzene) solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc.
