Closed Cell Sponge Rubber
Neoprene-EPDM-SBR
Overview
This blend combines the oil and chemical resistance of neoprene (CR) with EPDM’s UV/weather resilience, and SBR’s flexibility in cold conditions, resulting in an ultra-versatile, general-purpose closed-cell sponge. Available in densities from soft to firm, it meets critical ASTM D1056 standards and is an ideal fit for applications demanding broad environmental and mechanical performance.
Features
- Merges the durability of neoprene, weather resistance of EPDM, and cold adaptability of SBR.
- Spans a range of densities—from soft to extra-firm—tailored to compression requirements.
- UL 94 HBF or HF-1 flame ratings with superior oxidation, UV, and ozone.
- Reliable performance from –40 °F to +200 °F, ensuring adaptability across temperature extremes.
Benefits
- All-in-one solution for stressors like weathering, fluid exposure, and temperature fluctuations
