SILEX-SPONGE-HOSES MADE FROM HCR-SILICONE-RUBBER

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.

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 .
