Material Name |
PP (polypropylene) |
Characteristics of PP |
Low density (0.9g/cm3), it is one of the lightest plastics. The highest temperature of PP homo: 150ºC The highest temperature of PP co - homo: 90 - 100ºC polypropylene is high density, No Latent Chain, high crystalline polymer, have good combination property, white and translucent, wax; PP lighter than PE, PP is one of the lightest in normally plastic materials, the pp homo is more fragile over 0ºC, the PP co - homo material have lower heat distortion temperature (100ºC), low transparent, low glossiness, low hardness, But have stronger anti - stock strength. |
Compare with HDPE |
have higher strength and stiffness, and have excellent anti - bending fatigue, weakly impact performance, moisture resistance, anti - acid alkali ' s corrosion (except heavy H2SO4&HNO3), anti solvent solubility (except: aromatic and chlorhydrocarbons); Hi - dielectrics strength, weakly anti - ultraviolet rays characteristic. |
