About Our Silicone Sponge Profiles

A vast majority of our silicone sponge profiles are bespoke and manufactured to the customer’s exact specifications. Our highly experienced team are on hand at all stages of the process to give advice on the design for the manufacturability assessment of your profile. 

Silicone sponge is given its unique cellular structure through the use of blowing-agent additives. These additives give the material an off white colour but can be pigmented to achieve most colours if you require this. 

These bespoke silicone sponge profiles have so many benefits. The main one is its amazing heat insulation that comes from the materials’ very low thermal conductivity. It is also both oxidation resistant and has excellent sealing properties due to its chemical stability and its ability to deal with them.
