Rubber and Plastic Products/ Rubber and Plastic Sponge PVC/NBR
The thermal insulation material of Rubber and Plastic Sponge is made, through foaming processes, mainly from nitrile-butadiene rubber, and polyvinyl chloride, together with high quality accessory materials. This material is soft in nature and it is a top-grade heat preservation and energy conservation material. It doesn’t contain chlorofluorohydrocarbons.

This material is soft, with curve-bearing, cold and heat resistant, flame-resistant and waterproof qualities. Since it has low thermal conductivity, fine performance of shock absorption and sound absorption, it is widely used in central air conditioning, architecture, chemical industry, medicine, spinning and weaving, etc.

Standard length of hoses : 2 meters
Standard width of plates: 0.5 meter, 1meter.

Notes:
The above specifications are commonly used. We will customize the plates on special specifications of the user’s.

The plates and hoses are black in color; we will customize the color on special specifications of the user’s.

Suggest using plates for pipelines with outer diameter surpassing 89mm.

For thermal insulation materials with thickness surpassing 25mm, please use multi-layered overlap packing, until the required thickness is reached.
