The development process of PE-RT pipes

Ordinary PE pipes can only be used for cold water below 40°C, while PE-RT pipes can be used to transport hot and cold water at the same time.

In the 1990s, Dow Chemical first successfully developed PE-RT, and later companies such as SK and LG also developed their own brands.

These all belong to the first generation of PE-RT materials, referred to as PE-RTI.

With the continuous development of PE synthesis technology, since 2000, DOW Chemical, Basel and some Korean companies have launched the second generation of PE-RT, referred to as PE-RTII.

Compared with PE-RTI, PE-RTII has higher strength at high temperatures and better creep resistance. It can reduce wall thickness during use, which can save raw materials, reduce costs and increase diameter.
