Excellent Wear Resistance UHMWPE Bushing

Apr 10, 2019

We are a high-tech enterprise engaged in the research, development, production, sales and service of ultra-high molecular weight polyethylene new materials. We specialize in the production of UHMWPE sheets, special-shaped pieces and various engineering plastic products. We have the processing equipment (heating, molding, extrusion, mold, cutting) and other supporting facilities research, development, manufacturing, engineering design, construction and installation capabilities of the enterprise.

 

UHMWPE bushing has excellent wear resistance, good low temperature impact resistance, self-lubricating, non-toxic, water and chemical resistance. It has outstanding impact resistance, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubricating property, excellent chemical resistance, fatigue resistance, noise damping, and excellent performance. The use temperature is 70 to 110℃. Good cold resistance, can be used at -269℃. The product with a density of 0.985g/cm3 and a molecular weight of 4 million has a tensile strength at break of 50 MPa, an elongation at break of 400%, a flexural modulus of 600 MPa, and a cantilever beam notched impact. The amount of wear (MPC method) is 20 mm.

 

1. High wear resistance, higher than some metals. The wear resistance of UHMW-PE is proportional to the molecular weight, and the higher the molecular, the more wear resistant.

2. Excellent self-lubricating property and extremely low friction coefficient (0.05~0.11). When working with sliding or rotating, it is lubricated than steel brass and lubricating oil.

3. Impact Resistance, among the best in all engineering plastics, UHMWPE impact strength is twice better than PC, 5 times better than ABS, 10 times better than POM and PBTP. Its impact strength increases as the molecular weight increases. Even at low temperatures, it will not break if subjected to strong impact.

4. Excellent chemical resistance. In addition to strong fluorinated acid solution, it can resist corrosion (acid, alkali, salt) and organic medium in a certain temperature and concentration range.

5. Excellent non-stick, ultra-high molecular weight polyethylene surface adsorption is very weak, its adhesion resistance is second only to PTEE, not easy to adhere to materials.

6. Water-repellent, UHMWPE low water absorption, generally less than 0.01%, only 1% of PA6, so generally do not have to dry before the molding process.

7. Impact energy absorption, impact energy absorption value is good, with excellent noise reduction effect, low noise during work.

8. Low temperature resistance, even at -269 ° C is not brittle. It can work at temperatures from -269 ° C to 80 ° C for a long time.

9. Excellent resistance to environmental stress cracking, 200 times that of ordinary polyethylene.

10. Non-toxic, tasteless, no exudate. Access to food and medicine.

11. Anti-static, good flame retardant, anti-radiation.
