UHMWPE SHEET
UHMWPE( ultra high molecular weight polyethylene) is frequently used in high-wear applications, from wear strips under conveyors to guide rails in bottling plants, or scraper blades on road rollers.
UHMWPE sheets are used for lining bulk storage hoppers where low-friction, anti-stick and abrasion-resistant properties solve feed and wear problems.
UHMWPE sheet features:
1. Very high-wear resistance, seven times wear resistance than steel, four times than PTFE
2. Very high anti-impact resistance, two times impact resistance than PC, five times than ABS.
3. Good self-lubrication, better than steel and brass appended lubricating oil.
4. Good anti-corrosion resistance, it has very stable chemicals property and can endure the corrosion of all kinds of corrosive medium and organic solvent in certain rang of temperature and humidity.
5. Very high-inadhesion resistance, the surface of product hardly affixes other material.
6. Very high-impact resistance
7. Good low temperature resistance it still has the prolongation.
few other materials can reach to this performance.
8. Non-toxic and clean property
