Product Overview
Product Overview
BISCO 7130 is a soft, closed-cell silicone sponge that offers exceptional sealing, compression recovery, and environmental resistance. Designed for sensitive sealing interfaces, it combines lightweight flexibility with the durability of silicone rubber. 7130 ensures long-term performance in outdoor, industrial, and transportation applications.
Applications
Used in lighting enclosures, HVAC systems, electronic housings, and medical or aerospace assemblies that require gentle but reliable compression sealing under low force.
Performance Advantages
7130 maintains elasticity across –67 °F to +392 °F, resists UV, ozone, and weather aging, and meets UL 94 V-0 and HF-1 flame classifications. The fine-cell structure prevents moisture intrusion while allowing excellent compression recovery for dynamic sealing environments.
Key Properties
Density ≈ 24 lb/ft³; compression deflection ≈ 6 psi (25 % strain); compression set < 5 %; water absorption ≈ 1 %; operating range –67 °F to +392 °F; flame rating UL 94 V-0/HF-1; UV and ozone resistant.
