What are the characteristics of ultra-high molecular weight polyethylene?

Jun 24, 2019

Ultra-high molecular weight polyethylene sheet is a molecular weight of more than 1 million polyethylene. Ultra-high molecular weight polyethylene plate wear resistance is 1-7 times the steel plate, it is different from the steel plate is not resistant to acid and alkali and polymer polyethylene plate acid and alkali resistance, steel plate long-term exposure and the air oxygen molecule reaction to produce rust, and ultra-high molecular polyethylene plate will not be corroded.

Today we will talk about the characteristics of ultra-high molecular weight polyethylene sheet, I hope you have a certain help. The first is high wear resistance. One of the most striking features of improving molecular weight polyethylene is its high wear resistance, which is valuable in many engineering applications. Of all the plastics available today, its wear resistance is the best, and even many metal materials (such as carbon steel, stainless steel, bronze, etc.) are not as regularly milled as they are. As the molecular weight of polyethylene increases, the material becomes more resistant. Very high impact resistance. Ultra-high molecular weight polyethylene anti-flush strength and its molecular weight is related, the molecular weight is less than 2 million, with the molecular weight growth, impact intensity increased, in about 2 million to reach a peak, when the peak, the molecular weight will increase the impact intensity will decline. This is due to the molecular chain very sometimes interferes with its photocrystals, so that there is a large amorphous region in the macromolecule and thus can absorb large impact energy.

Ultra-high molecular weight polyethylene sheet is a linear structure with excellent comprehensive performance of thermoplastic engineering plastics, fiber is the world's third generation of special fiber, strength of up to 30.8cN/dtex, the strength is the highest in chemical fiber, but also has better wear, impact, corrosion resistance, light resistance and other excellent performance. Due to the ultra-high molecular weight polyethylene has a number of excellent properties. It offers significant advantages in the high-performance fiber market, from mooring ropes in offshore fields to high-performance lightweight composites.

Ultra-high molecular weight polyethylene sheet can be built to fill coal, lime, cement, mineral powder, salt, grain and other powdered files of the trailer, silo, chute lining, because it has excellent self-lubricity, non-stick. The above-mentioned powdered documents for storage and transportation facilities do not adhese the scene, to ensure a solid sponsor.

In industrial applications, it can be used as pressure-resistant containers, conveyor belts, filtration materials, automotive cushioning plates, etc., and the construction can be used as walls, partition structures, etc., and cement composite materials can be used to enhance the toughness of cement and improve its impact resistance. Because of its excellent wear resistance, impact resistance, it is widely used in the machinery manufacturing industry, can be made a variety of gears, cams, impellers, rollers, sheaves, bearings, shaft swares, shafts, cutting shafts, gaskets, gaskets, elastic couplings, screws and other mechanical components.
