Spongy silicone cords extrusion


We manufacture sponge silicone seals through extrusion in a wide variety of formats, including cords with diameters ranging from 2 mm to 75 mm, rectangular and square profiles from 2 mm x 2 mm to 75 mm x 75 mm, as well as tubes with inner diameters starting at 2 mm and outer diameters up to 100 mm.


Our extrusion process allows us to supply sponge silicone profiles and seals in any shape, based on a drawing or sample, with standard lengths of 25 m, 50 m, 100 m, 250 m, and 500 m. Additionally, upon request, we offer custom dimensions and pieces cut from 1 mm in length. We have special formulations for high temperatures, withstanding up to +250 ºC, and certified options for food contact according to FDA regulations.

Applications


Although there is no specific manual for its use, we recommend using sponge silicone profiles in applications where it is necessary to absorb differences in material tolerances to be sealed or welded, as well as in cases where significant compression of the material is required with optimal recovery of its shape.


We do not recommend using sponge silicone profiles in processes subjected to high mechanical stresses. For these cases, we offer custom solutions by manufacturing welded gaskets custom-made from any sponge silicone seal.


For your convenience, we have developed an app to facilitate the consultation of our silicone profiles and seals. Through this tool, you can find the profile you need and even download the drawing, along with our complete product catalog.
