Sponge Profiles / Gaskets
For special applications it is possible to produce cellular profiles which combine the typical properties of sponge articles with the individual properties of silicone type products.
Silex produces silicone-rubber sponge/foam profiles according to customer specifications for the industrial- as well as for the food markets (raw material conformity according to FDA).
Because of a high variety of different processes of blowing, the final products are very customized to your application depending on tensile strength, compression set und the type of cells (open / closed).
Furthermore Silex produce also profiles / gaskets made of 2 different rubbers, so-called "co-extruded profiles". This technology allows us to combine solid and sponge rubber in one profile / gasket.
Linked to the process the hoses always have a closed skin.
Dimensions / Specific gravity
|Wall Thickness||Width||Height||Specific gravity|
|2 - 20 mm||100 mm||50 mm||0,3 - 0,8 g/cm³|
|Shore A||8 - 13||12 - 18||18 - 22||22 - 28|
|Specific gravity, g/cm³ approx.||0,4||0,5||0,6||0,7|
|Thermal conductivity, W x m-1 K-1||0,07||0,1|
(The average thermal conductivity regarding non-cellular rubber is approx 0,2 - 0,3 W x m-1 K-1)
The standard set up of the articles are rolled rings or customer specified.
