Product Introduction
Product Description
NBR/PVC rubber foam insulation tube/pipe is made from the nitrile-butadiene rubber (NBR) and polyvinyl chloride(PVC) as main raw material and other high quality auxiliary materials through foaming, which is closed cell elastermic material，fire resistance, UV-anti and environmental friendly. It can be widely used for air condition, construction, chemical industry, medicine, light industry and so on.

Tips:
1) . R value is thermal resistance, it can be get from this formula: R=d/k.
"d" is thickness of foam material ( unit is meter), " k" means coefficient of thermal conductivity .
If our NBR foam insulation is 0.0356 w/(m.k), thickness is 0.025m.
So our R value is R=d/k=0.702 2).
2) . R=(rzloge(r2/rl)/k
