Rubber foam insulation materials

Huamei Brand Rubber foam Heat-Insulating & Heat-preservation Material is soft heat-insulating, heat-preservation and energy conservation materials made with advanced technology at home and abroad and advanced full-automatic continuous production line imported from abroad, and through development and improvement by ourselves, using butyronitrile rubber and polyvinyl chloride (NBR, PVC) with best performance as main raw materials and other high quality auxiliary materials through special procedure foaming .

This product is an closed cell elastic material, has such perfect performances as soft, anti-bending, cold-resistant, heat-resisting, fieblocking, water-proof, low thermal conductivity, shake-reduction and sound-absorption. It can be widely used for every kind of cold/ hot medium piping and containers in central control air condition, construction, chemical industry, medicine, light industry, textile process, metallurgy, boat, vehicle, electrical apparatus and other filds to reduce cold/thermal loss. In addition, because this product is easy to be installed, has beautiful appearance and never has any pollution, therefore, it is a new generation high quality heat-insulating, and heatpreservation material. As this material has soft and anti-bending performances, so it can be used to make handlebar sleeves of bodybuilding apparatus, medical equipment, covers or shields for articles of daily necessities.

In 2010,"Huamei" was the fist company approved China Well-known Trademark in the same industry .Huamei Brand Rubber foam insulation has been the only national inspection-free product and was continuously honored as high-quality product of Hebei province assured-quality product of Hebei province. Because of the excellent fie-blocking performance of this product, It obtained the certifiate for using-fie retardant products label, the certifiate for using the state building materials mark. Huamei rubber foam insulation has become network access product of Chinese product quality electronic supervision web. Exclusive electronic supervision code for a piece of product is printed on the quality certifiate of the package. Users can free inquire for truthfulness by calling 95001111 (The area which does not open that number can call 010-95001111 ) / messaging 106695001111 or logging on Chinese product quality electronic supervision web www.95001111.com .

 


Product Performance Advantages


Low conductivity factor

Conductivity factor is a very important index to measure the heat-insulation effect of the heat-preservation material .The lower the conductivity factor is, the better the heat-insulation performance will be. Conductivity factor of this material is 0.034w/m• k at average temperature 0 ℃ . As this product has high surface heat liberation rate, using the product with thinner thickness can get the same heatpreservation result as the traditional heat-preservation material at the same environmental conditions.

Good fire-blocking

According to fie-proof regulations of building design and fie-proof regulations of higher living building, the heat-preservation material used in piping and equipment should adopt the fie-blocking or non-combustion materials. This material contains a lot of fie-blocking and smoking-reducing raw materials. The smoking concentration generated from fire is very low. It shall not be melted when touched with fire and no any burning balls will be fallen down. The material has self-extinguishing characteristic. The specification of Huamei class 1 product is better than the national standard which used for burning products of construction filds. The burning performance of the product is not lower than C grade according to GB8624-2012 classifiation for burning behavior of building materials and products,ensuring safe and reliable

Vibration resistance

Huamei Brand Rubber Plastic Heat-Insulating & Heat-preservation Material has high elasticity, can reduce the vibration and resonate of the hot/cold water pipes in use in the largest degree.

Closed pore foaming , good damp-proof property

Huamei Rubber Foam Insulation owes perfect aperture-closing foam structure, all apertures are independent each other. The nonconnected air bubble forms the closed air layer that can enhance the heat-insulation performance efficiently, meanwhile the independent aperture-closing structure of can form much hindrance to moisture, even if the surface of the material was damaged, It also can prevent the water vapor into the inner material, so that maintaining the long-term steady of the heat-insulation effect at the same condition; the conductivity factor of water is 24 times higher than air' s, while the non-aperture-closing structure is in reverse.

Good pliability

Huamei Brand Rubber Foam insulation materials have good flexibility and tenacity which makes it easy to handle bent and irregular pipe in construction, saving both labor and material.

Beautiful appearance, easy to install

Because of the good softness, this product is easy to be installed.Tube Installing: The tubes can be installed after assembling or cut up them longitudinally and bind them with glue. With completed parts such as valve, three-way connection and elbow pipe, cut sheet material up and wrap those completed parts with the cut plate according to different shapes and then bind them together. That installing method guarantees the tightterial has smooth and straight surface as that of rubber and excellent performances, it is not needed to insert sealing layer or prevention layer, reducing the trouble in the construction and also guarantee that the installed appearance is beautiful and smooth. During the time of maintenance of equipment and pipe, the rest cut out from the material can be reused, which has the same performance.

Other advantages

Huamei Rubber Foam insulation Heat-Insulating & Heat-preservation Material can be used safely. Our products neither stimulate the skin nor harm health. The product can prevent mould from growing. They have excellent performance of acid-resisting and alkaliresisting. Because of those excellent performances, Huamei Rubber Foam insulation Heat-Insulating & Heat-preservation Material has become as an ideal heat-insulating material to protect pipe and tubes against environmental corrosion.

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.
