Advantages of ultra-high molecular weight polyethylene performance
Advantages of ultra-high molecular weight polyethylene performance:
1. The wear resistance ranks first in plastic, 4 times higher than nylon 66 and polytetrafluoroethylene, and 6 times higher than carbon steel;
2. The impact strength ranks first among plastics, twice that of PC and five times that of ABS, and can maintain high toughness at liquid nitrogen temperature (-196 ℃);
3. The self-lubrication performance is equivalent to that of polytetrafluoroethylene,
4. The impact energy absorption value is high among all plastics, and the sound attenuation effect is very good;
5. It has high chemical stability and can withstand various corrosive and organic media within a certain temperature and concentration range.
6. Extremely strong anti adhesion ability, second only to polytetrafluoroethylene;
7. Completely hygienic and non-toxic, can be used for contact with food and drugs;
8. The density is 56% lighter than polytetrafluoroethylene in all engineering plastics.
9. Good low-temperature resistance, with no changes in various properties at minus 256 degrees Celsius. The melting point is 136 degrees Celsius and the hot deformation temperature is around 85 degrees Celsius
Advantages of Nylon 66:
1. Excellent mechanical properties. Nylon has high mechanical strength and good toughness.
2. Good self-lubricating and friction resistance. Nylon has excellent self-lubrication and low friction coefficient, resulting in a long service life as a transmission component.
3. Good elasticity and fatigue resistance, able to withstand tens of thousands of bends
4. Excellent corrosion resistance, not moldy, not afraid of decay, with alkali resistance, but not resistant to acid and oxidants
Comparison between nylon and ultra-high molecular weight polyethylene:
1. High molecular weight polyethylene with a melting point of 136 ° C and a hot deformation temperature of 85 ° C in a temperature resistant environment; The melting point of nylon 66 is 230 °; Hot deformation temperature of 100 °;
2. Specific gravity: Ultra high molecular weight polyethylene with a specific gravity of 0.93; Easy to process; Nylon has a specific gravity of 1.17, with high hardness, high specific gravity, and high processing costs;
3. Nylon has high moisture absorption and insufficient dimensional stability;
Ultra high molecular weight polyethylene sheet has more diverse colors than nylon; The colors of ultra-high molecular weight polyethylene sheets include: white PE sheet, black PE sheet, blue PE sheet, green PE sheet, etc.
