Excellent sound insulation effect

porous structure
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.
High resilience
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.

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 .
Long service life
Silicone foam board has excellent UV resistance and anti-aging performance, which not only enables it to perfectly meet the requirements of outdoor applications but also makes the service life of this material particularly long, significantly better than that of rubber.


High and low temperature resistant
organosilicon has a main chain structure of Si-O bonds, and the side chains are connected to various other organic groups through silicon atoms. The bond energy of the Si-O bond in silicone is much greater than that of the C-C bond, so silicone products have high thermal stability. At high temperatures (or radiation exposure), the chemical bonds of the molecules do not break or decompose. It can withstand high and low temperatures and can be used within a very wide temperature range.
environment-friendly

green composition
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.
be decomposed into carbon dioxide and water
During use, silicone foam can be decomposed by microorganisms into carbon dioxide and water, and will not cause pollution to the environment. This biodegradability ensures that silicone foam does not impose a long-term burden on the environment after being discarded and can also be recycled and reuse
