Closed Cell Neoprene (CR) and Blended Neoprene (EPDM, CR, SBR) Foam
Neoprene foam and blended neoprene foam are durable and flexible closed cell materials with outsanding elongation. They provide good resistance to oils, water and chemicals while excelling as an insulator. Listed gasketing & sealing UL 48, UL50E, and UL 508. Whether you are insulating, sealing, or cushioning, these foam products deliver outstanding performance.
Applications include: Gasketing, sealing, insulation, weatherproofing, knee pads, wetsuits
- Terrific general purpose product
- Very good thermal insulator
- Good weather resistance
- Wide operating temperature range
- Good heat resistance
- Self extinguishing, many foams meet UL-94HF-1
- Good resistance to ozone, alkalis, and acids
