Rubber flex insulation tube

it is flex rubber insulation tube, main raw materials are NBR and PVC, it is fire resistance and has closed cell structure

Class one rubber flex insulation pipe is an excellent rubber-plastic foaming material, the main raw materials are NBR and PVC. it is widely used in medium pipeline of center air-conditioner, vehicle and shipping, chemical and medical industrial, getting the effect of reduce the cold and heat losing.

it has closed cell structure, and it is lower thermal conductivity, moisture resistance, superior combustion-proof, outstanding aging resistance, and easy installation.
