SFS has developed a silicone sponge that meets the latest fire and smoke approvals.  Independent testing has verified that SFS products meet EN45545-2 and UL94-V0. The SP-RL grades of silicone sponge have been developed for the rail industry.  SP-RL silicone sponges have inherent advantages of non-cellular silicone.

• Better Sealing
• Lower closure force, enabling thinner and lighter substrates to be used
• Reduced Weight

SP-RL can be extruded in specific shapes, with a smooth skinned surface.  The closed-cell sponge prevents the ingress of water and dust, and IP66 can be achieved.  Fabricated gaskets can be manufactured from the extruded profiles or cut from sheet.  Typical uses are:

• Door and roof seals
• Lighting Gaskets
• HVAC Seals and Gaskets
• Anti-vibration
• Acoustic Dampening
