Ultra-high molecular polyethylene (UHMWPE) is a high-performance material with excellent strength, rigidity and wear resistance. It is not limited by ordinary polymer materials, and has a wide range of applications and strong modification ability. The material has good mechanical properties, its strength is 5~8 times of that of ordinary polyethylene, and has extremely high fatigue durability, good impact resistance, and good elasticity. Therefore, it has good indentation resistance, good abrasion resistance, and can maintain high rigidity especially at low temperature. UHMWPE can also form a non-lubricating surface, so it can be used in extremely compact sealing devices. In addition, its structure is also very stable, its oxygen content is reduced, and its corrosion resistance will also be enhanced.
The molecular weight of ultra-high molecular weight polyethylene (UHMWPE) is more than 30 times that of general polyethylene. The main component of UHMWPE is polyethylene. Its chain property is more stable than that of general polyethylene. The benzene number is higher. The molecular chain formed is larger than that of general polyethylene. Its tensile strength is extremely high, which can exceed 200000 psi, and the tensile strength is 6000-8000psi.
Ultra-high molecular polyethylene has been widely used in practice and has been widely concerned by the society. It is an important material in aerospace, automobile, sports and leisure, medical treatment, semiconductor and other fields, and has been applied in various fields. In the automobile industry, UHMWPE is often used to manufacture various parts; In the aerospace field, it can be used to manufacture various fuselage and cabin parts; In the field of sports and leisure, it can be used to manufacture sports equipment such as skiing, diving and water skiing; In the medical field, surgical implants are made of ultra-high molecular polyethylene and its related compounds; In the semiconductor industry, UHMWPE can be used to manufacture various shell parts for semiconductor packaging.
