Eight Advantages of High Density Polyethylene
High-density polyethylene is known as the miracle plastic. It has the following characteristics:
1, excellent abrasion resistance, abrasion strength is 7 times that of carbon steel;
2, small coefficient of friction, good non-adhesion;
3, high impact strength, especially low-temperature impact resistance is excellent, is currently known to be high in plastic;
4, excellent chemical stability; in addition to a very few solvents to its corrosive, common inorganic and organic acids, alkalis, salts and organic solvents on this material are not corrosive. Ultra-high molecular weight polyethylene is similar to polytetrafluoroethylene in terms of chemical stability and is an inert material.
5, excellent anti-aging properties, in natural sunlight conditions, high density polyethylene aging life of 50 years.
Ultra-high molecular weight polyethylene is molecular weight higher than 1.5 million linear polyethylene, as a new type of engineering plastics, set a variety of excellent performance in one:
1, abrasion resistance of the plastic, 4 times higher than nylon 66 and PTFE, 6 times higher than carbon steel;
2, impact strength column plastic, 2 times PC, ABC 5 times, and can maintain high toughness in liquid nitrogen temperature (-196 ℃);
3, self-lubricating and PTFE equivalent, the coefficient of friction is only 0.07-0.11;
4, impact energy absorption value in all plastics for the high value, good sound deadening effect;
5, high chemical stability, in a certain temperature and concentration range can resist a variety of corrosive media and organic media;
6, anti-adhesion ability *, second only to PTFE;
7, * health non-toxic, can be used for contact with food and drugs;
8, density in all engineering plastics in small, 56% lighter than PTFE.
In addition to heat resistance, the comprehensive performance of UHMW-PE exceeds the "plastic king" PTFE, so it is known as "amazing plastics" in Europe and the United States, in the textile, paper, packaging, transport, machinery, chemical, mining, petroleum, agriculture, construction, electrical, Food, medical, sports and refrigeration technology and many other fields, and increasingly favoured by people.
