Propertiesand advantages of PP: 1. The PP resin is a white waxy solid with avery low density between 0.89 and 0.92 G / CM3. PP is light in theplastic material except for 4--1-ene P4MP. Polypropylene has goodcomprehensive properties, abundant raw materials, simple productionprocess and low price. PP mechanical properties and polyethylene,its strength, stiffness and hardness are relatively high, goodgloss. But it's still low in plastic. If you need high strength,you can choose high-crystalline polypropylene or filled, reinforcedpolypropylene. The impact strength of PP is temperature dependent,and its impact strength is low, especially at low temperature. Theimpact strength of PP is also related to molecular weight,crystallinity and crystal size. Because of its high crystallinityand regular structure, it has excellent mechanical properties. Itsstrength and hardness are higher than that of Dhpe, but at roomtemperature and low temperature, because of its high molecularstructure regularity, its impact strength is poor and its molecularweight increases, the impact strength also increases, but theprocessing performance becomes worse, polypropylene also hasexcellent bending fatigue resistance, its products can be bent 106times at room temperature without damage. With good heatresistance, melting point at 164170 degrees, the product can bemore than 100 degrees temperature disinfection, in the case of noexternal force, 150 degrees do not deformation, embrittlementtemperature-35 degrees, in less than-35 degrees will occurembrittlement. Because it hardly absorbs water and its insulationis not affected by humidity, it has high dielectric property andcan be used to make heating electrical insulating paper with thetemperature rising.
