Plastic material pipes are more and more important and popular in room heating, cooling and water service and sanitary distribution system. PE-RT means Temperature-Resistance Polyethylene. PE-RT pipe for heating floor is made of YUCLAIR DX800 produced by n SK Corp, and recognized as an ideal floor heating product for its sanitary conditions, favorable standards, and good heat radiation. When the hot water pipes are circling under the floor, the heat will be dispersed through the floor.
It is widely use in hot & cold water distribution, floor heating system. residential or industrial plumbing.
Because high density polyethylene can not bear high temperature which results in its failing to solve indoor hot water supply problem. Therefore, polyethylene of raised temperature resistance (PE-RT) was developed in USA as a new kind of pipeline material able to bear the high temperature. Besides all the advantages of high density polyethylene, it’s well done in resolving problem of hot water supply. PE-RT is copolymer of comonomer based on ethylene-octane. It can control appropriately the number and distribution on the branched chain of polyethylene molecular chain during polymerization, which makes PE-RT material gain excellent physical mechanics performance and higher heat resistant performance without crosslinked. It can be used 50 years or so under the circumstance of transmitted water temperature 70°C(centigrade degree)& the pressure of 0.97MPa.
PE-RT physical mechanics performance:
PE-RT materials own excellent physical mechanics performance without crosslinked:
1.Good thermal stability & long-term resistance of pressure
2.Excellent resistance to environmental stress cracking performance
3.Good flexibility and toughness
4.Ability of low-temperature impact resistance
5.Excellent health performance
