BISCO® BF-1000 Extra Soft Silicone Foam
Rogers BISCO® BF-1000 Extra Soft Silicone Foam is an ultra-compressible, open-cell silicone foam designed for applications requiring low closure force, gentle gasketing, and high durability. Its extra-soft construction delivers exceptional cushioning, vibration isolation, and environmental sealing performance while resisting UV, ozone, and extreme temperatures. BF-1000 is an ideal choice for outdoor enclosures, electronics protection, and applications needing long-term performance with minimal gasket stress.
Applications include: Active safety, cold supply chains, gap filling, gasketing and sealing, LCD gaskets, shock absorption, and vibration management.
- Resistant to UV, ozone, and extreme temperatures
- Ideal for sealing, cushioning, and vibration control in sensitive or delicate assemblies
- Available in thicknesses from 0.063 in to 1.0 in
