PPR pipe materials used
Nov 29, 2016

Production of polyethylene pipe polyethylene odorless, nontoxic, feel like wax, with excellent low temperature resistance (minimum use temperatures up to -70~-100), good chemical stability, resistant to most acid and alkali erosion (not with oxidation properties of acid-resistant), not soluble in common solvents at room temperature, Hygroscopicity small.

But PPR pipe as linear molecules slowly soluble in some organic solvents, and no swelling occurs, and excellent electrical insulating properties; but the polyethylene to environmental stress (chemical and mechanical action) is very sensitive to heat aging poorly.
