Huamei Class B1 Rubber Foam Insulation                                            


Embossed pattern rubber and plastic board is a new type of rubber and plastic insulation board which integrates heat insulation, decoration and noise reduction, which has been developed by Huamei group for a long time.It has the following performance characteristics:


1. Huamei embossed rubber and plastic board is more practical, not only has the superior performance of Huamei rubber and plastic, but also has strong decoration.


2. Huamei embossed rubber and plastic board has a relief pattern and relief group logo, and printed with three rows of equidistant white product logo, its design is very beautiful, with beautiful appearance, novel design, strong sense of three-dimensional and many other advantages. If the relief face is used inside, it can also increase the bonding strength between the equipment and the rubber and plastic. If the relief face out of use, in addition to enhance the decorative, but also increase the product sound-absorbing noise reduction function.

1. The above specifications are those in common use; special specifications are available at customers' request.

2. Rubber foam sheet and tube are normally in black. Other colors are available at customers' request.

3. It is recommended to use sheet where outer diameter of tube exceeds 89mm.

4. Multilayer packing is recommended where the thickness of heat insulation materials needs to be greater than 25 mm.

5. The width of the sheet are available at customers' request for a scope of 1m to 2m.


Requirements table of thickness for installation(As the environment conditions are different in various area ,so the following datas are just for reference) :

Environmental conditionsDimension of heat-preservation pipeSuitable thickness at temperature of piping (mm)

Factors to be considered for determining thickness of the heat-preservation material:

1.Environmental temperature: The higher the temperature is, the thicker the material is.

2.Relative humidity: The higher the relative humidity is, the thicker the material is.

3.Temperature of medium:The higher the temperature of medium is, the thicker the material is.

4.Diameter of pipe: The more the diameter of pipe is, the thicker the material is.
