PE-RT/PB is mainly made of ethylene and copolymerized with octane. The linear main chainof ethylene has controllable branches which will significantly improve heat endurance andpressure resistance. Because no treatment needs to be done after cross linking during theproduction, the materials of finished products are more even and reliable. PE-RT/PB resinhas been applied by pipeline manufacturers for over 20 years among European developedcountries and the U.S. Through continuous improvement and reform, PE-RT resin now hasoutstanding long-term hydrostatic and high temperature resistance,pipes made of whichwill become the new generation of heating pipeline system popular in Europe and the U.S.
