Excellent sound insulation effect

porous structure
Silicone Sponge can effectively absorb and block the transmission of sound for its cloesed cell structure.
When sound passes through Silicone Sponge, sound waves are constantly reflected, refracted and scattered within the porous structure, gradually weakening the energy of the sound.
High resilience
Cetification Silicone Sponge 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.

Outstanding sealing effect

excellent resistance to compression set
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 .
Strong comprehensive ability
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 keep good performance during wide temperatuer range from -60~220℃(-76℉-428℉).

Excellent electrical insulation

Stable electrical insulation performance
Silicone rubber sponge 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.
Safe and reliable insulating materials
Corona resistance life of Cetification Silicone Sponge is approximately a thousand times that of polytetrafluoroethylene. The arc resistance life is approximately 20 times that of fluorine rubber.
Therefore, silicone foam material is an excellent material for electric heating products

environment-friendly

degradable
Silicone sponge is green material,especially cetification silicone sponge.The material will degrade into carbon dioxide and water. Silicone sponge wont harm the devices and environment.
safe to human body 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
