The raw material of PERT floor heating pipe is a kind of medium density polyethylene with very stable mechanical properties, which is formed by catalytic copolymerization of ethylene and octene monomers. It does not require cross-linking in the production and processing process, the production process is simple, easy to control, and the quality of the pipe is stable and reliable: PERT floor heating pipe is the only plastic that does not require cross-linking and can perform long-term hydrostatic performance at water temperature below 60 degrees. tubing. Under the condition that the working temperature is >60 gradd ac mae'r pwysau yn 0.8MPa, gellir defnyddio ei fywyd gwasanaeth yn ddiogel am tua 50 mlynedd.
