GD-FLEX uv resistant pipe insulation

Specifications uv resistant pipe insulation

1)UV resistence treatment

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

  GD-FLEX uv resistant pipe insulation     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
