UHMWPE plate and PTFE plate are currently the two most widely used non-metallic plastics on the market. The common features of both are engineering plastic plates with corrosion resistance, self-lubrication and low friction coefficient. The different characteristics show that UHMWPE plate is more wear-resistant than PTFE plate, but the high temperature resistance is not as good as PTFE plate. Next, I will summarize the main differences between the two in detail:
UHMWPE plate and PTFE plate are currently the two most widely used non-metallic plastics on the market. The common features of both are engineering plastic plates with corrosion resistance, self-lubrication and low friction coefficient. The different characteristics show that UHMWPE plate is more wear-resistant than PTFE plate, but the high temperature resistance is not as good as PTFE plate. Next, I will summarize the main differences between the two in detail:
1. Wear resistance: UHMWPE plate has excellent wear resistance, the higher the molecular weight, the better the wear resistance of the material. 2. Friction coefficient: because UHMWPE has self-lubricating properties. Therefore, it can work in sliding or rotating mode without lubricating oil, which is better than steel and copper in lubricating conditions.
3. Water absorption rate of material: UHMWPE plate has very low water absorption rate. It hardly absorbs water, does not swell in water, and is much smaller than nylon. 4. Chemical resistance: UHMWPE plate has high chemical stability, and can withstand the action of various corrosive media (acid, alkali, salt) and organic solvents such as acid, alkali, salt, etc. within a certain temperature and concentration range.
5. Non-toxic: UHMWPE plate is odorless, non-toxic, odorless, non-corrosive, and has physiological cycling and physiological adaptability. The US Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) allow it to be used It is used in the occasions where it is in contact with food and medicine, so it is suitable for industries that require high hygiene conditions such as food and medicine.
