Request a Quote
Introduction
UHMWPE plate and pipes are products made using an engineering plastic that features an outstanding performance at low temperatures. This material has an excellent shock resistance, and wear resistance, as well as great self-lubricating abilities. It has a very high molecular weight and features a better performance over ordinary polyethylene or other engineering plastics. Additionally, it has many features such as wear resistance, impact resistance, corrosion resistance, self-lubrication, shock absorption, low temperature resistance, non-toxic health, non-adhesion, water absorption, light weight, minimal surface tension, non-polarity and more.
- Dredge pipes, coal gas pipes, nature gas pipes, marine industrial pipes, water pipes, oil pipes, ash pipes for coal-fired power plants.
- Various non-ferrous metal and black metal mine tailings pulp transportation pipelines, coal mine pulp transportation pipelines, food processing pipelines, chemical industry pipelines, food and beverage industry pipelines.
- Injection molding for various mechanical components: various assembly line wear- resistant components such as food processing machinery, printing and dying machinery, packaging machinery, belt conveyor idlers, low temperature resistance parts in frozen machinery and the nuclear industry, auto parts and more
- Liner plate for bulk carriers, cement bins, coal bins and mining cars.
- Pipe formation through extrusion processing to cover submarine cables or optical cables.
- It can be hollow blown into various shapes for chemical liquid containers and beer, wine bottles, as well as automobile and motorcycle fuel tanks and more.
