| Introduction: 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. Features: 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%, minimize the water absorption rate) 6 Environmental, on-CFC. 7 low Flammability B1 Grade, self-extinguishing, no fireball drops, limited fire spreading 8 Excellent seamless UV jacketing protection ,have excellent performance of UV resistance, water proof, bird peck-Protective and protect from mechanical destroy.

| How to distinguish between EPDM and NBR |
| Method: put one piece of insulation pipe into Microwave at medium heat for heating two minutes separately. After two minutes, the NBR insulation will become very smelly and heavy smoke. EPDM doesn't have any special smell and no smoke. The work temperature of EPDM can reach 175℃，But NBR/PVC can only reach 105 ℃ |

 EPDM insulation pipe :before putting into microwave |
 Put EPDM insulation pipe into microwave and turn on microwave at medium heat for two minutes. After two minutes. The only change is the insulation pipe become expansion. |
 NBR/PVC insulation pipe: before putting into microwave |
 Put ENBR/PVC insulation pipe into microwave and turn on microwave at medium heat for two minutes. After two minutes. The heavy smoke happened and very smelly. The insulation body changes the shape seriously. |
