The Characteristics of Ultra high molecular weight polyethylene
Ultra high molecular weight polyethylene is a kind of thermoplastic engineering plastic with linear structure and excellent comprehensive properties, is a kind of impact resistance, wear resistance, good self-lubricating performance, and excellent low-temperature performance of engineering plastics. The main features are as follows:
1. Wear resistance and anti-sliding friction. Ultra high molecular weight polyethylene pipe wears resistance than the general pipe 4-7 times, stainless steel 27.3 times.
2. Impact resistance, the impact toughness of ultra high molecular weight polyethylene is the highest among all engineering plastics, and its impact strength is more than 10 times of PE100 at room temperature. With the decrease in ambient temperature, its impact resistance is stronger.
3. The corrosion resistance of ultra high molecular weight polyethylene can be used in concentrated hydrochloric acid with a concentration of less than 80%, in the concentration of less than 75% sulfuric acid, and the concentration of less than 20% nitric acid in the performance is quite stable.
4. The self-lubricating property is better than that of oil-lubricated steel or brass. Ultra high molecular weight polyethylene pipes provide better dry lubrication in harsh, dusty, and sandy environments. Able to move freely, to protect the related workpiece from wear and tear. The friction coefficient is only 0.07 ~ 0.12, which is 1/5 of ordinary PE, 1/6 of new steel pipe, and 1/20 of rubber.
5. Non-toxic, ultra high molecular weight polyethylene material is the national certified environmental protection material, non-toxic, tasteless, anti-pollution, and anti-moth New Thermoplastic Engineering Plastics
6. Low-temperature resistance, anti-aging, Ultra High Molecular weight polyethylene tube can work in the temperature of -269 ° C to 80 ° C for a long time because the unsaturated molecular group in the molecular chain is very few, the molecular weight is big, the stability is high, the aging speed is especially slow, longer service life.
7. The surface of ultra high molecular weight polyethylene pipe is non-adhesive because of its low friction coefficient and non-polarity.
8. The crack resistance of ultra high molecular weight polyethylene pipe is the best. It has been proved by the tensile test that it has 100 ~ 300% elongation rate. It can keep certain deformation and not break when it is subjected to huge external and internal pressure or bending stress.
