BISCO® 7130 Silicone Sponge
Rogers BISCO® 7130 Silicone Sponge is a soft-grade, closed-cell silicone material engineered for flame-resistant gasketing, sealing, and environmental protection in high-performance applications. Designed to meet the stringent BMS 1-60 Type 1, Grade A specification, BISCO 7130 provides outstanding flame resistance, low compression set, and consistent sealing under long-term compression. It is ideal for use in aerospace, transportation, electronics, and other environments where flame retardancy, durability, and thermal stability are critical. It is a drop-in replacement for the Bisco 7129 Series
Applications include: Gap filling, gasketing and sealing, HEV enclosures, LCDs, shock absorbers, sound blocking, spacers and bin liners, and thermal solutions.
- Available in sheet format (3.18 mm to 25.4 mm / 0.125" to 1")
