For special applications it is possible to produce cellular hoses which combine the typical properties of sponge articles with the individual properties of silicone type products.
Silex produce silicone-rubber sponge hoses 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 hoses always have a closed skin.

| Thermal conductivity, W/mk | 0,07 | 0,1 |
(The average thermal conductivity regarding non-cellular rubber is approx.
The standard set up of the articles are rolled rings or customer specified.
Type of hoses
- Open cells up to most closed cells.
- Natural white color or special colors according to the RAL-system.
- Food contact applications in accordance with FDA conformity of the used raw materials (FDA § 177.2600).
- Very high thermal- and sound-isolation level.
- High sealing behavior because of easy compression and high elasticity (compensation of tolerances).
- Typical silicone properties are very high hot-air resistance, weathering- and ageing resistance (UV, ozone) as well as very low variation of properties over a range of temperatures .
