Silicone Sponge Rubber Pad

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 rubber has outstanding electrical properties. Its outstanding advantage is that its dielectric strength, power factor and insulation performance are minimally affected by temperature and frequency changes.

The corona resistance and electrical resistance of silicone rubber are also excellent.

Its corona resistance life is approximately a thousand times that of polytetrafluoroethylene. The arc resistance life is approximately 20 times that of fluorine rubber.

Years later, the material can degrade into carbon dioxide and water. Silicone sponge wont harm the devices and environment. 

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
