PP 〈Polypropylene 〉 is a semi-crystalline thermoplastic with high impact resistance, strong mechanical properties, resistance to various organic solvents and acid-base corrosion, and is widely used in industry.
PP is a non-toxic, odorless, tasteless, milky white high 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, and its water absorption in water is only 0.01%, and the molecular weight is about 80,000 to 150,000. The moldability is good, the shrinkage rate is large (1% to 2.5%), and the surface gloss of the product is good.
Applicable to automotive, electrical, mechanical, instrumentation, radio, textile, defense engineering accessories, daily necessities, turnover boxes, medical and health equipment, building materials, etc.
