Thermal insulation of silicone foam

 

Silicone foam, also called foamed silicone, is a new type of organic material with high resilience and low density. It has the characteristics of high and low temperature resistance, waterproof and fireproof, small compression deformation rate and mechanical fatigue resistance. It is widely used in all walks of life.

 

As the core energy supply station of the new energy vehicle, the battery is subjected to multiple tests such as high and low temperature, dust and humidity throughout the body. It can be seen how important the protection of the battery shell is; the silicone foam material has the properties of high and low temperature resistance, waterproof and flame retardant, high-performance sealing, etc., and can be used as a protective cover for the battery shell to escort the driving of the car.

The base station housing is generally made of aluminum alloy cast iron. In order to connect the aluminum base station housing into a continuous conductor, it needs to be realized by the electromagnetic shielding efficiency of the conductive silicone foam. Since the 5g base station is basically located outdoors and has been in a corrosive environment such as high temperature, cold, and humidity for a long time, the working environment is relatively harsh, so the thermal conductive silicone foam plastic used in the housing must have strong anti-aging and anti-ultraviolet capabilities.

 

In addition, silicone foam is also used for shock absorption, sealing, buffering and noise reduction of high-speed railways and automobiles; it is widely used in indoor and outdoor waterproof and flame retardant, small household water lines and various products that require heat insulation, sound insulation, and anti-static.

 

Now with the continuous upgrading of products in some industries, the performance requirements for silicone foam are getting higher and higher. Many customers ask whether silicone foam can provide insulation. Here, our engineers will briefly introduce some functions of silicone foam, hoping to be helpful to you.

 

Silicone foam features

 • Rich thickness, the thickness of 0.35～1.5mm provides options for various spaces that need to be filled

 • Good sealing, can provide good dust sealing effect for equipment under moderate compression

 • Long-lasting elasticity, providing long-term stable positioning for parts that need to be fixed

 •Super soft and compressible, the compression ratio is up to 90%

 • Strong surface, easy to match with protective film, not easy to chip

 • Good shock absorption performance, can effectively protect components and reduce impact damage

 • Excellent resistance to compression set, providing long-term protection for equipment

 

Advantage

 • Flexible and easy to compress

 • Excellent durability

 • Noise reduction possible

 

application

 •Mobile phone speakers, power modules, lampshade seals, automobiles, electronic equipment and computer communication equipment and other industries

 •Fixed bonding and protection of electronic products, cameras, speakers, LCD monitors, signs, etc.

 •Battery, press the foam on the plug

 • Computer, electronic equipment foot pads, etc.

 

Silicone foam also plays a key role in our daily life due to its strong thermal insulation, heat resistance and sealing properties; for example, if a refrigerator is installed with it, the temperature inside the refrigerator will not be affected by external factors during hot summer months prevent the battery from directly contacting the high temperature and dust generated during the operation of the vehicle, and provide effective energy for the normal operation of the vehicle; silicone foam can also be installed on the engine for sound insulation; ultra-thin high-tech silicone foam used in mobile phones Plastic can effectively block the high temperature generated during the operation of the mobile phone and ensure the normal use of the mobile phone. In addition, silicone foam insulation products are also widely used in my country's railway trains, warships and other industries.
