Excellent sound insulation effect
open cell porous structure
The open pores of porous sound-absorbing materials allow sound waves to enter. When sound waves propagate in the tortuous pores, they rub against the pore walls and convert sound energy into heat energy for dissipation.
The damping characteristics of silicone material Promote sound absorption
Silicone is a high-molecular polymer with high internal damping properties.When sound waves cause slight vibrations of the silicone skeleton, the friction between molecular chains will consume additional energy
Wide temperature range stability
Silicone has excellent heat and Cold resistance
Open cell silicone sponge maintains elasticity within the range of -60℃ to 250℃ (ordinary rubber hardens at -20℃ and ages at 150℃).
Chemical stability
The main chain of silica gel is inorganic siloxane, and its inertness is much higher than that of organic polymers.
It is resistant to acids, alkalis, organic solvents and ozone, and has a lifespan of over several years.
