We can extrude silicone sponge profiles in any shape, sponge cords starting at 2 mm diameter up to 75 mm diameter, square and rectangular profiles from 2 mm x 2 mm to 75 mm x 75 mm and sponge silicone tubes from 2mm inside diameter to 100mm outside diameter.
Our manufacturing process allows us to supply any shape given a drawing or sample in several coil lengths (25 m, 50 m, 100 m, 250 m and 500 m). Other lengths and cut parts from 1mm onwards can be supplied on request.
We have specific formulations for high temperature resistance (up to +250 ºC) and for foodstuff applications (FDA grade silicone).
¿When to use a sponge silicone profile instead of a solid silicone profile?
Certainly there is no instructions manual, but our advice is to use them in those applications where there is a need to absorb tolerance differences from those materials you need to seal/join, or that you need to compress the profile noticeably and that it keeps its memory. Our advice would be not to use sponge profiles where mechanical stress or strain is present.
Ask for our possibilities of manufacturing vulcanised seals from any given sponge profile.
For your convenience we are working on building an enquiry system by which you will be able to consult online and download all our extruded silicone profiles, together with a complete silicone profile catalogue.
