2015 Ultra High Molecular Weight Polyethylene Wear Blocks Manufacturer
The largest engineering plastic production base in the country, a leading manufacturer of ultra high molecular weight polyethylene sheets aiming for the top 500 enterprises — Shandong Ningjin Xinxing Chemical Co., Ltd.
Performance Introduction of Ultra High Molecular Weight Polyethylene Wear Blocks:
1. High Wear Resistance: Among all engineering plastics, UHMW-PE exhibits outstanding wear resistance. The higher the molecular weight, the more wear-resistant the material, even surpassing many metal materials (such as carbon steel, stainless steel, bronze, etc.). For example, UHMW-PE pipes have a lifespan of 4-6 times that of steel pipes under conditions of strong corrosion and high wear, while improving transportation efficiency by 20%. It fully demonstrates the advantages of 'energy-saving, environmentally friendly, economical, and efficient'.
2. Corrosion Resistance: It is not corroded in alkaline solutions and can be used in concentrations at 80°C. It performs stably in 75% concentrations and 20% nitric acid. It is also stable against seawater and liquid detergents.
3. Extremely High Lubricity, Extremely Low Friction Coefficient: The static friction coefficient is 0.07, and it has good self-lubricating properties, making it an ideal material for bearings, bushings, sliders, and liners. Choosing UHMW-PE as the friction component in equipment not only enhances wear resistance but also achieves energy-saving effects. The high lubricity of this material is due to the addition of wax, which significantly improves its lubricating properties.
4. Impact Resistance: It leads in impact resistance among plastics. Whether subjected to strong external impact or internal pressure fluctuations, it is difficult to crack. Its impact strength is 10 times that of nylon 66, 20 times that of PVC, and 8 times that of PTFE; especially in low-temperature environments, its impact strength reaches high values, providing extremely safe and reliable support for conveyor systems.
5. Aging Resistance: It has stable performance and good aging resistance, suitable for both ground and underground burial, with a lifespan of 50 years without aging. According to ASTM testing (load 4.6 kg/cm2), the heat distortion temperature is 85°C, with a usable temperature reaching 90°C, and under special circumstances, it can be used at even higher temperatures. UHMW-PE is a highly tough material with excellent low-temperature resistance, maintaining a certain degree of ductility at -269°C without signs of brittle fracture. 6. Electrical Properties: It has high volume resistivity, with a breakdown voltage of up to 50KV/mm, and a dielectric constant of 2.3. It is suitable as a structural material in electrical engineering over a wide range of temperatures and frequencies.
7. Hygiene and Non-Toxicity: UHMW-PE is odorless, non-toxic, and non-corrosive, possessing physiological inertness and adaptability. It is approved by the FDA and USDA for use in contact with food and pharmaceuticals.
