Improve wear resistance. One of the most striking properties of increased molecular weight polyethylene is its extremely high wear resistance, which is valuable in many engineering applications. Among all plastics, its wear resistance is the best, and even the regular wear resistance of many metal materials (such as carbon steel, stainless steel, bronze, etc.) is not as good as it. As the molecular weight of polyethylene increases, the material becomes more wear-resistant. , extremely high impact resistance. The impact strength of ultra-high molecular weight polyethylene is related to its molecular weight. When the molecular weight is less than 10,000, as the molecular weight increases, the impact strength increases, reaching a peak around 10,000. After this peak, the impact strength will decrease if the molecular weight increases again. . This is because the molecular chain often hinders its optical crystallization, so that there are large amorphous regions in the macromolecules that can absorb large impact energy.
Very low friction coefficient. Ultra-high molecular weight polyethylene is very wear-resistant, has a low friction coefficient and good self-lubricating properties. It is an ideal material for bearing sleeves, sliders and linings.
Using ultra-high molecular weight polyethylene as friction parts of equipment can not only improve the wear-resistant life, but also achieve energy saving effects.
, good corrosion resistance.
, Very low water absorption. Ultra-high molecular weight polyethylene has a very low water absorption rate. It absorbs almost no water and does not swell in water. It is much less absorbent than nylon.
, thermal properties. According to the (load./) method, the heat deformation temperature is ℃. Under a smaller load, the use temperature can reach ℃. In special cases, it is allowed to be used at a higher temperature, because ultra-high molecular weight polyethylene is It is a material with excellent toughness, so its low-temperature resistance is also very good. At -℃ low temperature, it still has a certain degree of ductility without any signs of brittleness.
, electrical properties. Ultra-high molecular weight polyethylene has excellent electrical properties over a wide temperature range, and its electrical properties change very little over a wide temperature and frequency range. In the heat-resistant temperature range, it is very suitable for use as structural materials in electrical engineering and as materials in paper mills.
Non-toxic ultra-high molecular weight polyethylene is tasteless, non-toxic, odorless, non-corrosive, and has physiological circulation and physiological adaptability.
Its properties, especially wear resistance, impact resistance and self-lubricating properties, are the best among engineering plastics.
