OMEFLEX rubber foam insulation used butyronitrile rubber and polyvinyl chloride NBR/PVC with best performance as main raw material and other high quality auxiliary material through foaming and other special procedure.This product has perfect performances such as soft anti-bending cold-resistant heat-resisting fire-blocking water-proof low thermal conductivity and sound-absorption. It can be widely used for every kind of cold/hot mediumpiping and containers in central control air condition construction chemical industry medicine vehicle electrical

apparatus and other fields to reduce cold/thermal loss. OMEFLEX rubber foam insulation was deeply loved by themasses of customers.

1, the higher the temperature, the material is
2, the relative humidity is bigger, thicker materials;
3, medium temperature is lower, thicker materials;
4. The larger the diameter of the pipe, the thicker the material.
