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.
