General Purpose Silicone Sponge Gaskets

Using our in-house manufacturing facilities, CB Frost can produce Silicone sponge gaskets in a wide variety of shapes and sizes to suit your requirements.

General purpose Silicone sponge has a fine closed cell structure, with a low degree of moisture absorption, encapsulated by a soft, smooth outer skin – this helps to add some resilience to the material. Off-white in colour, Silicone sponge gaskets can withstand temperatures of between -60 ˚C and 200˚C.

With a high resistance to ozone, UV and general weathering, general purpose silicone gaskets are well suited to applications in a vast range of industries.

  • We can produce Silicone sponge gaskets in thicknesses ranging from 1.5mm to 25mm thick, all of which are manufactured on our overhead or swing arm presses
