Features of UHMWPE Crane Leg Support Pads
Features of ultra high molecular weight polyethylene wear-resistant pressure pad and crane support leg pad:
1. Ultra-high molecular weight polyethylene is odorless, non-toxic, odorless, non-corrosive, physiologically circulatory and physiologically adaptable.
2. Excellent corrosion resistance, low friction coefficient, small specific gravity and good resistance to high energy radiation. Ultra-high molecular weight polyethylene is chemically stable and resistant to corrosion by various corrosive media such as acid, alkali, salt and organic solvent at a certain temperature and concentration range;
3, self-lubricating is equivalent to PTFE, the friction coefficient is only 0.07-0.11;
4, the impact energy absorption value is ** value in all plastics, the muffling effect is very good;
5. 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.
6, anti-adhesive ability is extremely strong, second only to polytetrafluoroethylene;
7, completely hygienic and non-toxic, can be used to contact food and drugs;
8, wear resistance in the crown of plastic, 4 times higher than nylon 66 and PTFE, 6 times higher than carbon steel;
9. High chemical stability, resistant to various corrosive media and organic media within a certain temperature and concentration range;
10, non-adhesive;
11. The impact strength ranks first in plastics, twice as much as PC, 5 times as much as ABS, and can maintain high toughness at liquid nitrogen temperature (-196 °C).
