China Closed Cell Silicone Foam

The porous structure of silicone foam can effectively absorb and block the transmission of sound.

When sound passes through silicone foam, sound waves are constantly reflected, refracted and scattered within the porous structure, gradually weakening the energy of the sound.

Silicone foam has the material property of high resilience, which enables it to quickly return to its original shape after being subjected to external force.

It can effectively absorb the energy of sound waves, thereby reducing the intensity of sound and effectively reducing the transmission of vibration and noise.

Sanpu silicone foam can ensure that the cover plate or panel always maintains a consistent closing force, making various shells, seals and contact surfaces closely adhere.

It can effectively controll destructive impact energy, prevent the invasion of dust and particles, and thus play a powerful protective role .

A good sealing ring also needs to face the challenges of gas, chemical and solvent resistance, temperature load, and flame retardancy.

Our silicone foam sheets are up to the task and does not contain plasticizers or residual chemicals that could contaminate equipment, nor is it corrosive to metals

silicone foam is made from raw materials such as silicone resin raw rubber, fillers, vulcanization accelerators, and foaming rubber. Most of these raw materials are non-toxic, odorless, and do not contain other harmful additives or auxiliaries. Moreover, they have good biological adaptability. 

Compared with other materials, it does not release harmful substances during use(even in high tempertature environment). It has stable physiological inertness and will not cause irritation or allergic reactions to the human body. It is safe for both the human body and the environment
