Flexible Fireproof Rubber Pipe Thermal Insulation Tube Or Air Conditioning Pipe Insulation

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 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 absorptive 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 Class 0/1 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.

Note:
1.The a
bove specifications are commonly used specifications. Special specifications are available according to request of customer.
2. Rubber foam sheet and pipe are normally in black. Other colors are available according to requirements of customer.
3. It is recommended to use sheet when outer diameter of pipe exceeds 89mm.
4. Multiple layers packing is recommended where the thickness of heat insulation materials which you need are greater than 25mm.
5. The width of
the sheet can be customized to 1-2 meters according to customer’s requirements.

Note:Factors need to considered when choosing the thickness of insulation material
1. The higher the environmental temperature is, the thicker the material is.
2. The higher the relative humidity is, the thicker the material is.
3. The lower the temperature of the medium is, the thicker the material is.
4. The larger the daimeter of the pipe, the thicker the material is.
