Properties and applications of UHMWPE Rod

1.       Product characteristics of UHMWPE Rod

Excellent abrasion resistance, good resistance to low temperature impact, self-lubricity, non-toxic, water and chemical resistance, heat resistance is better than general PE, disadvantages are heat resistance (thermal deformation temperature) low, poor processing and molding, surface hardness, rigidity, creep resistance as general engineering plastics, expansion coefficient larger. UHMWPE has poor fluidity and extremely high viscosity in the molten state. It is a rubber-like high-viscosity elastomer. At the early stage, it can only be molded by pressing and sintering methods.

Higher mechanical properties than ordinary high density polyethylene. Excellent impact resistance, stress cracking resistance, high temperature creep resistance, low friction coefficient, self-lubrication resistance, excellent chemical corrosion resistance, fatigue resistance, noise damping resistance, nuclear radiation resistance, etc.

The operating temperature is 100 ~ 110.Good cold resistance, can be used at -269.The product has a density of 0.935g/cm3 and a molecular weight of 2 million. Its tensile strength at break is 40MPa, elongation at break is 350%, elastic modulus at bending is 600MPa, and the cantilever beam is constantly impinged by the gap. Abrasion (MPC method)20mm.

2.       Application field of uhmwpe rod
Uhmpe bar can replace carbon steel, stainless steel, bronze and other materials for textile, paper making, food machinery, transportation, medical treatment, coal mine, chemical industry and other sectors. Such as textile industry on the shuttle, shuttle rod, gear, coupling, sweeping rod, buffer block, eccentric block, rod sleeve, swing consequences and other impact wear resistant parts. Paper industry to do box cover plate, wiper plate, compression parts, joints, transmission machinery seal shaft, deflector wheel, scraper, filter, etc. The lining of hoppers, silos and chutes for powdery materials in the transport industry.

Uhmwpe rod can be used for all kinds of mechanical parts, including food machinery gear, worm wheel, worm, bearing. Chemical pumps, valves, baffles, filters. Medically, it can also be used for heart valves, short surgical parts, artificial joints and birth control implants. Sports to do skating floor, ground track, ski, motor sledge parts.

Application scope and polyamide, ptfe similar, wear resistance than carbon steel, do gear, bearing, bearing bush, star wheel, valve, pump, guide rail, sealing packing, equipment lining, sliding plate, artificial joints, fiber for bulletproof jacket, rope, etc.

Ultrahigh molecular weight polyethylene (uhmwpe) rod has many excellent properties, but few people know its existence, which is mainly due to the lack of previous research on the melt characteristics of uhmwpe, and the processing method is basically still in the backward press-sintering process. In recent years, with the continuous development of uhmwpe processing technology, its products have been successfully applied in many fields.

Color: primary color (white), black, other colors can be customized
