Silicone Sponge Tubes
For special applications it is possible to produce cellular tubes which combine the typical properties of sponge articles with the individual properties of silicone type products.
Silex produce silicone-rubber sponge tubes 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 customized to your application depending on tensile strength, compression set und the type of cells (open / closed).
Linked to the process the tubes always have a closed skin.
Dimensions / Specific gravity
|Inner Diameter, mm||Wall thickness, mm||Gravity, g/cm³|
|2 - 70||2 - 20||0,3 - 0,8|
|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.
