Viking Extrusions have 30 years’ experience supplying silicone sponge sheeting and other silicone components to industry worldwide. Over this time, we have gained a vast amount of knowledge and expertise which allows us to ensure you receive the right material for your application.
Silicone sponge rubber is an elastomeric material with a closed cell structure that has been developed to provide exceptional sealing properties, vibration dampening, insulation and cushioning.
We can supply silicone sponge sheeting to the following specifications:
Silicone sponge sheet has many advantageous properties including:
Silicone sponge sheeting offers excellent compression properties and is used to produce a variety of gaskets and seals. It is especially useful when sealing surfaces are not smooth. Typical applications for silicone sponge sheeting include:
With open cell sponge, each cell or bubble is openly connected to the next cell. As these cells are not separated water, dust and moisture can make its way through the cell structure.
An example of this would be a commonly used sponge for cleaning, which soaks up water by allowing it to pass through each cell to be held within the sponge.
Closed cell sponge has very different structure to open cell sponge. In a closed cell sponge each cell is a completely closed separated sphere, with air trapped in each cell. The lack of connectivity between cells means that water, dust or moisture cannot readily pass through the cell structure. Closed cell sponge has very low water absorption and is an ideal material choice for sealing applications where water and dust ingress are to be prevented.
The term “sponge” is generally used to describe a closed cell product and the term “foam” for an open cell product.
