The wear resistance of crane stabiliser pads ranks first among plastics
UHMW crane stabiliser pads are more resistant to abrasion and compression than wooden pads and iron pads used before, and they are lighter in weight, easier to handle and more convenient to use, increasing work efficiency and extending the crane stabiliser pads. Service life.
Performance of ultra-high molecular weight polyethylene wear-resistant crane stabiliser pads:
- The wear resistance ranks first among plastics, which is 4 times higher than nylon 66 and 6 times higher than carbon steel;
- The impact strength ranks first among plastics, which is 2 times that of PC and 5 times that of ABS, and can maintain high toughness at liquid nitrogen temperature (-196 ° C);
3. Excellent self-lubrication, the friction coefficient is only 0.07-0.11;
- The impact energy absorption value is high in all plastics, and the sound insulation effect is very good;
- High chemical stability, can resist various corrosive media and organic media in a certain temperature and concentration range;
6, very strong anti-adhesion ability;
7, completely hygienic and non-toxic, can be used in contact with food and drugs;
8, superior corrosion resistance, low friction coefficient, small specific gravity, good resistance to high energy radiation performance;
9.Ultra-high molecular weight polyethylene is chemically stable, and can withstand the corrosion of various corrosive media such as acid, alkali, salt and organic solvents within a certain temperature and concentration range;
10.Ultra high molecular weight polyethylene is odorless, non-toxic, odorless, non-corrosive, and has physiological circulation and physiological adaptability.
11.Non-adhesiveness;
12.When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature decreases to 140 ° C. Ultra-high molecular weight polyethylene can even be used under the action of liquid nitrogen. Its use temperature can reach below 269 ° C and still have a certain mechanical strength.
