Silicone Sponge Profiles. In Merefsa we are specialised is silicone sponge profile manufacture, we can supply densities from 0.25 gr/cm3 to 0.8 gr/cm3.
In the extrusion of profiles and sponges of spongy silicone our standard is broken white with a density of 0.25 gr/cm³, although we can manufacture any color from a minimum quantity and with densities of 0,3 gr/cm³, 0,4 gr/cm³, 0,5 gr/cm³, 0,6 gr/cm³ and 0,8 gr/cm³.
Spongy Silicone profiles Extrusion
We manufacture extrusion sponge silicone gaskets in any format, spongy silicone laces from 2 mm to 75 mm in diameter, rectangular and square spongy profiles, from 2 mm x 2 mm to 75 mm x 75 mm and silicone sponge tubes from an inner diameter of 2 mm to an outer diameter of 100 mm.
Our extrusion process of fluffy silicone profiles and weatherstrips allows us to supply any type of shape under a plane or sample, in lengths of 25 m, 50 m, 100 m, 250 m and 500 m. On request we can also make other measurements and pieces cut from 1mm in length. We have formulations for high temperatures (up to +250° C), and others suitable for food contact (FDA) as well as specific formulations for the railway sector, complying with the European standard EN45545.
Applications
Certainly there is no manual in this regard, but our advice would be to use them for those applications, in which either it is because we must absorb differences in the tolerances in the materials that we must seal or weld, or because we have to compress the material in a remarkable way and we need you to have a good memory.
Our advice would be not to use sponge silicone profiles in those processes that suffer from mechanical stress.
