What is the difference between pe bar and upe bar, pe bar is also called polyethylene bar, pe bar is a kind of high crystallinity, non-polar thermoplastic material, the appearance is milky white, and it is translucent to a certain extent in the thin section . upe bars are thermoplastic engineering plastics with a molecular weight higher than 1.5 million. Has a molecular chain length 10-20 times that of HDPE. We understand the difference between pe sticks and upe sticks, so let's take a look at their respective uses.
The pe stick is odorless, non-toxic, feels like wax, has excellent low temperature resistance (minimum operating temperature can reach -70~-100 ℃), good chemical stability, and can resist the erosion of most acids and alkalis (not resistant to oxidation properties) acid), insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation performance; low density; good toughness (also suitable for low temperature conditions); good tensile properties; good electrical and dielectric insulation; low water absorption; Low water vapor permeability; good chemical stability; non-toxic and harmless.
PE bars are mainly used in medical appliance parts, seals, cutting boards, sliding profiles. They are widely used in machinery, chemical industry, electric power, clothing, packaging, food and other industries. It is widely used in gas transportation, water supply, sewage, agricultural irrigation, mine fine particle solid transportation, as well as oil field, chemical industry, post and telecommunications and other fields, especially in gas transportation.
