silicone sponge rubber white square profile adhesives

excellent temperature resistance, oil resistance & weathering resistance (UV / ozone resistant), FDA conform

The silicone foam is made of methyl silicone rubber (VMQ) and is a rubber compound for versatile thermal sealing applications, and at low and high temperatures, the material properties of the rubber compound change only insignificantly. The silicone foam is produced (extruded) in a special process (expansion) into a sponge rubber foam and has a predominantly open-cell structure with a closed outer skin. The rubber is odorless, tasteless and electrically insulating, is characterized by a very good elasticity in the cold area and is approved for use in the food industry (FDA compliant). The resistance to oils, fats, oxygen, ozone, UV rays, weathering and aging is very good, as well as good against weak acids and alkalis.

The sponge rubber is a foam in the commercial hardness or density and adapts under light pressure immediately and very well to uneven surfaces. The good recovery behavior (i.e., the material returns to its original shape) allows for optimal sealing. A compression of the material from 30% to max. 50% before sealing is recommended, with a compression of more than 50% damaging the material structure and greatly reducing the recovery behavior.
