Special-shaped parts features:
1.ultra-high molecular weight polyethylene board wear-resistant plastic, and molecular weight, the greater the material's wear-resistant and impact resistance;
2. The impact strength of Uhmwpe sheet is the high value in the existing plastics, even at 70 ° C, it still has quite high impact strength
3.Self-lubricating;
4. Ultra high molecular weight polyethylene board with very low water absorption. Therefore, the special-shaped parts manufacturers, its physical and mechanical properties and the use of working conditions in the humidity factor independent;
5.ultra-high molecular weight polyethylene plate chemical stability, at a certain temperature,In the concentration range can resist acid, alkali, salt and other corrosive media and corrosion;
6.UHMWPE board is odorless, non-toxic, odorless, non-corrosive, with physiological cycling and physiological adaptability.
7.When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature drops to 140 ° C. Uhmwpe can even be used under the action of liquid nitrogen, its service temperature can reach 269 ° C, still has a certain mechanical strength.
Ultra high molecular weight polyethylene (UHMWPE) , even at -40 °C, still has a very high price of impact-resistant special-shaped parts, even at -269 °C, it can still maintain a good impact-resistant performance, this excellent low-temperature characteristics, the application of UHMWPE is extended to the field of low temperature engineering. Low coefficient of friction. Uhmwpe is very wear-resistant, and low coefficient of friction, self-lubrication is good, is an ideal bearing sleeve, slider, lining material. The use of ultra high molecular weight polyethylene as the friction parts of equipment, in addition to improving the wear life of plastic parts, but also can receive energy-saving effect. Good chemical resistance. Uhmwpe has good chemical corrosion resistance, except for concentration, it will not be corroded in all lye, acid, it can be used at temperature (80 OC concentrated hydrochloric acid, < 20% , < 75% sulfuric acid is also stable, it is very stable to water, liquid washing, ultra-high molecular weight polyethylene (UHMWPE) sheet in aromatic or halogenated compounds (especially at high temperatures) is very easy to swelling, so special-shaped manufacturers, the application of special attention. Very low water absorption. Ultra-high molecular weight polyethylene water absorption is very low, it is almost non-absorbent, non-swelling in water, much smaller than the water absorption of nylon.
