Product Description

Brief introduction of Rubber Foam

The rubber foam products of our company are produced by imported high-end technology and automatic continuous equipment. We have developed a rubber foam insulation material with excellent performance through in-depth research. The major raw materials we use are NBR/PVC.

The main characteristics are: low density, close and even bubble structure, low thermal conductivity, cold resistance, extremely low water vapor transmissibility, low water absorbtive capacity, great fireproof performance, superior anti-age performance, good flexibility, stronger tear strength, higher elasticity, smooth surface, no formaldehyde, shock absorption, sound absorption, easy to install. The product is suitable for a wide range of temperature from -40℃ to 120℃.
Our Class0/1 insulation is generally black in color, other colors are available upon request. The product comes in tube, roll and sheet form. The extruded flexible tube are specially designed to fit the standard diameters of copper, steel and PVC piping. Sheets are available in standards precut sizes or in rolls.
