HOWO rubber and plastic ultra high molecular weight polyethylene cantilever beam base plate prominent features:
1. The wear resistance is higher than that of all kinds of pure plastics, and increases with the increase of molecular weight; When UHMWPE is paired with steel and copper, it is easy to produce adhesive wear, and the wear of mating parts is small. The service life is higher than that of steel, and the wear resistance is 3 ~ 7 times that of carbon steel and stainless steel;
2. The self-lubricating property is very good, and the rolling friction coefficient is low in plastic. It can work in the form of sliding or rotation without lubrication. Its lubricity is better than that of steel and copper with lubricating oil!
3. It has strong absorption of impact energy and friction silencing performance, and has the advantage of low friction noise;
4. Impact strength column plastic is one of the existing plastic varieties that is more impact resistant. The impact strength at room temperature is comparable to that of polycarbonate PC, and the impact strength at low temperature is even better than that of polycarbonate PC; Its impact strength is 8 times that of ABS, 10 times that of PA66, 22 times that of POM and 25 times that of PBT!
5. The fatigue resistance is very good, and the fatigue strength is more than 500000 times;
6. The molecular weight is large, but there are few unsaturated bonds, so it has excellent chemical corrosion resistance and can withstand all kinds of corrosive media, such as acid, alkali, salt, and all kinds of organic solvents;
7. The environmental stress cracking resistance is very good, 200 times that of ordinary ethylene, and the stress cracking resistance time is up to 4000 hours; And high temperature creep resistance is also very good; UHMWPE also has good radiation resistance;
8. Super heat resistance is not high, thermal deformation temperature HD
9. Good electrical performance, good electrical insulation and antistatic property, volume resistivity >1015 Ω Cm, the dielectric strength is 90kv/mm, and the dielectric constant is 2.3;
10. There is no adsorption on the surface, and it has no adhesion to any material, with low water absorption (<0.01%);
11. It has good resistance to high-energy radiation;
12. Non toxic, tasteless, and free of exudates;
13. Excellent aging resistance. Under natural sunlight, the aging life of UHMWPE is 50 years;
14. It has excellent machinability.
