Красочные черный lldpe/pe электрические EPDM теплоизоляции труб

Product Overview

Description

  colorful jacketing EPDM thermal insulation pipe

 

 

 

 

Our EPDM closed cell tube and sheet insulation is composed of Ethylene-Propylene-non-conjugatedDieneRubber, It is a kind of nonpolar , Saturation and no cracks rubber. Our EPDM insulation provides many advantages over most rigid insulations for cooling and heating lines

 

 

 

 

 

1 outstanding ultraviolet and weather resistance

 

2 work temperature(-200Celsius --+175Celsius)

 

3 Stable moisture & vapor resistance gene 

 

4 low&stable thermal conductivity 

 

5 closed cell foam structure,water absorption rate is low(The wall thickness of closed cell foam is 4 micron. closed cell foaming capacity is above 95%,water absorption rate less than 5%) 

 

6 Environmental,Non-CFC. 

 

 

 

7 low Flammability B1 Grade, self-extinguishing, no fireball drops, limited fire spreading

 

 

 

 

Seamless UV resistant jacketing insulation pipe

black jacketing pipe

blue jacketing pipe for cold water

red jacketing pipe for hot water
