Low-pressure polyethylene

Polyethylene is the most common polymer used in the industry. It can be reused by all known methods. Welded by all main ways: by hot gas, filler rod, friction, contact welding. Polyethylene has good frost resistance, is operated at a temperature of from -50°C to +80°C. Harmless to humans. Polyethylene has good dielectric properties, high impact resistance, has a low vapor and gas permeability. Does not react with the alkalis of any concentration, with solutions of neutral, acidic and basic salts and some acids.

Scope

Containers (boxes, cans, bottles, etc.), electrical engineering, storage tanks for aggressive liquids, membranes for waterproofing, profile details for mechanical engineering, household appliances, automotive and building industry, products for medicine and many others.
