Closed Cell Sponge
Closed Cell Foam
Closed cell foam is made by subjecting a rubber compound to a gas, such as nitrogen, under high pressure. Produced from 100% neoprene polymer, most closed cell neoprene sponge products meet UL 94HF-1 flame rating. Closed cell sponges are a common material for custom rubber gaskets and seals. Ideal for sealing it effectively reduces liquid and gas flow for industries in where liquid resistance is critical, such as marine, HVAC, and automotive.
- UL 94HF-1 flame rating.
- Resistant against oils, grease, ozone, alkalis and acids.
- Can withstand temperatures ranging from -70 – 200°F, UV rays, ozone, and most moistures
The unique internal structure of closed cell foam provides versatility to be used in a number of applications. Used as thermal insulators and packaging materials for electronic and computer components, clothing, metal products, furniture, food, plants and any kind of goods. Other major applications are marine equipment, aerospace, construction, and industrial production (containers, crafts, etc).
