The difference between conventional silicone sponge

Stronger mechanical properties
Higher density silicone foam means that when the material is subjected to tensile or tear forces, it has more silicone matrix to bear the load, thus being stronger, more durable and less likely to be pulled or torn.
Better sealing effect
The higher the density, the lower the compression set . Because high-density silicone foam have stronger elastic resilience, they can still maintain good sealing performance after long-term pressure (for example, as sealing gaskets).


Longer service life
Higher density,means stronger mechanical strength. Stronger mechanical strength means longer life service.Especially, the with the performance of anti UV and anti aging.
mature processing technology
A variety of high-density silicone foam orders have been refined, excellent the thickness tolerance control .The product quality is stable.
