foaming tube, heat insulation tube,NBR-PVC heat insulation tube - Qingdao Wisdom International Trading Co. Ltd

Thermal conductivity coefficient is a main physical index to show the material thermal conductivity ability, it is relevant to the material component, density, molecular structure and environment humidity. So, at first, we adopt fully closed cell structure, keep the products density controlled within the best scope, reduce the water absorption rate, insure stable thermal conductivity. On the other hand, we adopt advanced production craft to set a lower thermal conductivity, the initial thermal conductivity coefficient is 0.034w(m.k) Energy saving effect will be obvious for long term operation and low maintenance.

2. High combustion-proof performance

Combustion performance is an important index to measure the security performance of the material. Our product is composed of high grade compound material mixed with plenty of combustion-proof and smoke reduction material. It will not melt when come across the fire. It has low smoke density, low toxicity and self-extinguish.
