SILEX-SPONGE-PROFILES MADE FROM HCR-SILICONE RUBBER
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).
Linked to the process the hoses always have a closed skin.
Dimensions (borderline)
| Wall Thickness, mm | Width, mm | Height, mm | Specific gravity, g/cm³ |
| 2 - 20 | 100 | 50 | 0,3 - 0,8 |
Typical properties
| 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/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.
Profiles can be made with a self-adhesive tape and different kinds of filaments for preventing elongation. Furthermore, the manufacturing of O-rings or frames is possible by adhesion or vulcanisation.
Type of profiles
- Open cells up to most closed cells.
- Natural white colour or special colours 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 behaviour 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.
