The difference between silicone sponge

Regularly arranged holes
The regularly arranged holes help heat to dissipate more quickly, ensure more uniform heating and extend the service life
more conducive to the evaporation of water vapor
Small raised dots on the back make the evaporation of water more effective.It is more targeted when used in certain scenarios where water is needed but there cannot be standing water

The same characteristics as silicone sponge

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 .

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.
