FAQ

 

 

Q: What are silicone sponges made of?

A: Most commercially available silicone sponge products are made from gum based polydimethylsiloxane (PMDS). The silicone elastomer is expanded at the time it is heat cured; the expansion process creates the closed cell sponge structure.

Q: What is the hardness of silicone sponge?

A: Hardness: 5 degrees ShA. Silicone sponge has excellent properties of compression, especially when the insulating surface is not smooth.

Q: How to make a silicone sponge?

A: Closed cell silicone rubber sponge is created “by subjecting a silicone base to an inert gas at an elevated pressure, preferably after a pre-curing step, reducing the pressure to allow the base to expand to produce closed cell silicone foam and curing this expanded foam at an elevated temperature”.
