RDPAP7
Advantages:
1.Heat resistant:The highest work temperature is 95°C ,working pressure is 1.25MPa.
2.Longevity:more than 50 years under normal condition
3.Antiknock:burst pressure can reach 6.0Mpa with safer system
4.Better Resistance performance of oxygen
5.Lower coefficient of heat conductivity:the lowest is 0.45W/m.k
6.Easy to install,no connectors
Application:
1.Cold or hot water supply
2.Heating system including flooring heating and radiating system
3.Central air conditioning system
4.Industrial liquids transportation,etc
