Random Copolymer of propylene from the category of thermo PEX is the traditional and the best raw material for PEX tubing. Obtained it by adding a chain of molecules of propylene ethylene molecules. Unconditional benefits of PEX tubing are durable, low thermal conductivity, high temperature resistance, ability to withstand short-term increase in temperature media up to 95 ° C, low weight, lack of electrical conductivity, good adaptability to manufacture and assembly. PEX is environmentally friendly, easily washed out during operation, while maintaining hygienic properties throughout life, which is 50 years.
