Uhmw roller chain guides advantage

The roller chain guides use the most advanced materials: Ultra high molecular weight polyethylene.

1. The wear resistance of ultra high molecular weight polyethylene ranks first in plastics, and the larger the molecular weight, the higher the wear resistance and impact resistance of the material;
2. The impact strength of ultra high molecular weight polyethylene is the highest in existing plastics, and there is still a relatively high impact strength even at 70 ° C;
3. Self-lubricating;
4. Ultra-high molecular weight roller chain guides have extremely low water absorption. Therefore, its physical and mechanical properties are independent of the humidity factor in the operating conditions used;
5. Uhmw roller chain guide is chemically stable, and can resist corrosion of various corrosive media and organic solvents such as acid, alkali and salt at a certain temperature and concentration range;
6. Curved guide rail is odorless, non-toxic, odorless, non-corrosive, physiologically circulatory and physiologically adaptable.
7. non-adhesive；
8. When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature drops to 140 °C. Ultra-high molecular weight polyethylene can even be used under the action of liquid nitrogen, and its use temperature can reach 269 °C, still have a certain mechanical strength.
