YANTAI HUAMEL ENERGY_SAVING CONSTRUCTION MATERIAL CO.,LTD.is specialized in providing new supporting insulation materials.
Main production ：Glass Wool、Extrusion Molding、Rubber And Plastic、Rock Wool、Aluminum Silicate、Polyurethane
Product description
Nowadays science and technology is developing rapidly. A good product can't be created without advanced and precise equipment and excellent raw materials. Huamei Group owning international quality raw materials suppliers and adopting the international advanced equipment to ensure perfect and high quality products.
Huamei Group owns a perfect supply system of raw materials. It can choose the raw materials that satisfy standard.Through accurate weighing and ingredients. Receiving the tightly middle process control and strict product testing.Ensuring the specification of product completely better than the requirement of GB/T 17794-2008.
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°C . As this product has high surface heat liberation rate, using the product with thinner thickness can get the same heat-preservation result as the traditional heat-preservation material at the same environmental conditions.
Good fire-blocking
Acording to and , the heat-preservation material used in piping and equipment should adopt the fire-blocking or non-combustion materials. This material contains a lot of fire-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 fields. The burning performance of the product is not lower than C grade according to GB8624-2012 ,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
Glass Fiber
The penetration coefficient of apertured structure on water vapour is very high. As a result, after its operating for a period, its conductivity factor shall be risen and the heat-preservation effect shall be reduced greatly.
Foamed Polytene (PEF)
Aperture-connection structure has higher penetation cofficient of water vapor. Its material is hard but britte and easy to be damaged with short life.
Huamei Rubber Foam Insulation
It owes perfect aperture-closing foam structure, all apertures are independent each other. The non-connected 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 plability
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 installd. 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 tihtterial 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 alkali-resisting. 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.
