1 / 3BISCO Silicone Foam
Rogers BISCO silicone foam for compression sealing, shock and vibration protection, and heat shielding in transportation, communication, and industrial applications — available as cellular, solid, and specialty grades.
Material Type
Rogers BISCO silicone foam — cellular / solid / specialty sealing foam
Key Properties
Compression set resistance, shock and vibration absorption, high-temperature stability
Alternative Grades
AG-231 (closed-cell, medium density) / AG-311 (open-cell, extra soft) — UL-94 V-0 HF1
Thickness Range (Alternatives)
0.032" to 0.500" in gray, black, and white variants
Overview
ALS Tape supplies Rogers BISCO silicone foam for gasketing, sealing, cushioning, and thermal insulation in transportation, communication, and industrial applications. BISCO silicone foam offers exceptional compression set resistance and reliable shock and vibration protection across a wide temperature range, outperforming standard polyurethane foam in sustained high-temperature environments. Three form factors — cellular foam, solid silicone, and specialty silicone sealing foam — cover the range from compressible sealing applications to rigid thermal and electrical insulation. ALS converts BISCO roll stock into fabricated components including gaskets, heat shields, dust seals, cushions, and insulation pads. Alternative grades (AG-231 closed-cell and AG-311 open-cell) are available for designs where direct BISCO equivalence is required — both carry UL-94 V-0 HF1 rating with smooth surface texture and excellent compression set resistance.

Key Features
Exceptional Compression Set Resistance — BISCO silicone foam maintains its compressed sealing geometry over long service life, delivering reliable sealing in assemblies subject to sustained compression loading.
Shock and Vibration Protection — Absorbs mechanical shock and damps vibration energy in portable devices, automotive enclosures, and industrial equipment where component protection is critical.
High-Temperature Stability — Silicone chemistry provides reliable performance across a wide temperature range, suitable for engine compartments, power electronics, and high-temperature industrial environments.
Cellular, Solid, and Specialty Grades — Material selection from open-cell foam to solid silicone to specialty sealing foam, matched to compression, insulation, and environmental sealing requirements.
Roll Stock to Fabricated Parts — ALS converts BISCO roll stock into custom-dimensioned gaskets, heat shields, seals, dust seals, cushions, and insulation components for assembly-ready delivery.
UL-94 V-0 HF1 Certified Alternatives — AG-231 (medium density closed-cell) and AG-311 (extra soft open-cell) offer UL-94 V-0 HF1 certified equivalents in gray and black, thickness range 0.032" to 0.500".
