Factory Supply PE UHMW Roller¹

Product Description Pe Uhmw rollerUHMW-PE(Ultra high Molecular Weight Polyethylene )is a thermoplastic engineering plastic with the average molecular weight more than 9.0 million. (PE only has the molecular weight between twenty to two hundred thousand. ) This kind of material with five top performance of high-wear-resistance, good-chemical resistance, low-temperature resistance, self-lubrication and high-impact resistance, which is regarded as a "surprised" engineering plastic of excellent comprehensive capacity and competitive price.Main characteristics:1. Very high-wear resistance, seven times wear resistance than steel, four times than PTFE2. Very high anti-impact resistance, two times impact resistance than PC, five times than ABS.3. Good self-lubrication, the same as PTFE, better than steel and brass appended lubricating oil.4. Good anti-corrosion resistance, it has very stable chemicals property and can endure the corrosion ofAll 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, ten times impact resistance than PA66, eight times than PTFE.7. Good low temperature resistance, in liquefied nitrogen (- 196o C), it still has the prolongation.Few other materials can reach to this performance.8. Non-toxic and clean property, UHMW-PE, which is the material that Food and Drug Administration (FDA) and United States Department of Agriculture (ASDA) permit to apply in food and medicine fields.PropertyItem No.UnitValueMechanical Properties1Densityg/cm30.94-0.962average molecular weightg/molMore than 9.0 million3Tensile strength (23oCin air)MPa224Breaking strengthMPa425Tensile strain at break%6006Charpy impact strength (notched)mJ/mm 2No break7Ball indentation hardnessN/mm 2428Shore D hardness--D659Abrading(sand slurry experiment)            --100
