Ultra-high molecular weight polyethylene (UHMW-PE) material is a thermoplastic engineering plastic with a molecular weight of more than 2.5 million. Compared with ordinary polyethylene, due to its huge molecular weight, it has the following special properties.

Excellent abrasion resistance: UHMWPE material has extraordinary abrasion resistance. Under certain conditions, its wear resistance is 7 times that of carbon steel, 27 times that of brass, 5 times that of nylon 66 and polytetrachloroethylene, and 10 times that of rigid PVC.

Excellent impact resistance: UHMWPE material not only has good wear resistance, but also has high impact resistance, and its impact strength is greater than 140 kg/cm.

Good self-lubrication: The friction coefficient of UHMWPE material is 0.07-0.11. After being used as the lining plate of the closing hopper under the coal bunker, basically no sticking and blocking of the silo will occur.

Excellent corrosion resistance: UHMWPE material has excellent corrosion resistance. Except for a few strong oxidants, it is resistant to corrosion by various chemical substances, such as acids, alkalis, salts, etc.; no electrochemical corrosion occurs, and it is also very good for various oil stains and harsh environments (except for ambient temperature over 90 °C). adaptability.

Very small water absorption: the water absorption of the ultra-high molecular weight polyethylene material used as the lining board of the lower closing hopper of the coal bunker is less than 0.1%.
