PE-RT/EVOH（三层）地暖管

• Vispert oxygen barrier (EVOH) tube has high hydrostatic strength under high temperature conditions, and there is no need to worry about brittleness under low temperature conditions; it has good fluidity during processing and has good melt strength during welding. The EVOH in the middle is oxygen resistant The layer effectively isolates the corrosion of the pipeline and the system from the penetration of oxygen and acid-base substances, and extends the service life of the system. The inner wall of the tube is smooth, which effectively reduces resistance, is not easy to produce scale, and ensures ultra-high thermal conductivity. Excellent cold resistance, no freezing and cracking in winter, easy to bend, and easy to construct. It is becoming a new generation heating pipe system popular in Europe.
