Ultra-high molecular weight polyethylene (uhmwpe) refers to polyethylene material with a molecular weight of more than 1.5 million. It is a thermal engineering plastic. It combines the superior properties of all plastics and has wear resistance, impact resistance, chemical corrosion resistance, self-lubricating, resistance to It has excellent properties such as low temperature, aging resistance, flame retardant, antistatic, not easy to adhere, and non-absorbent.
Features of Ultra High Molecular Weight Polyethylene Sheet (uhmwpe):
1. Extremely high wear resistance, due to its unique molecular structure, the wear resistance is higher than that of ordinary metal products, 6.6 times that of carbon steel, 5.5 times that of stainless steel, 27.3 times that of brass, 6 times that of nylon, and 6 times that of polytetrafluoroethylene. 5 times that of fluorine.
2, the self-lubricating performance is good, the wear coefficient is small, the flow resistance is small, and the energy is saved.
3. High impact strength and good toughness, even at low temperature, it will not break under strong impact.
4. Excellent resistance to chemical corrosion and can withstand almost all acid, alkali and salt media (except concentrated sulfuric acid, concentrated nitric acid and a few organic solvents).
5, tasteless, no exudate.
6. Good electrical properties and extremely low water absorption.
7. Excellent resistance to environmental stress cracking, which is 200 times that of ordinary polyethylene.
8. Excellent low temperature resistance, not brittle even at -180 degrees.
