Red Oxide Silicone Sponge Extruded Foam Sleeving (Tube): our silicone rubber foam sleeving can be expanded into silicone sponge by using blowing agents. The resulting sponge has fine non-interconnecting cell structure encapsulated by a soft, smooth, outer skin.
Silicone sponge is an excellent sealing medium, due to its stable chemical structure and good recovery. It can be extruded into profiles and produced in sheet form. The profiles can be butt-joined or mitred to form continuous seals; the sheet can be cut into gaskets. It has minimal water absorption (IP65-66 achievable) and excellent heat insulation.
It also offers good resistance to ultraviolet light and corona, arching and ozone. Oxidation is virtually non-existent. It is excellent for vibration damping and cushioning components and generally resistant to moderate or oxidising chemicals.
