Closed Cell Sponge

Closed Cell Foam

Closed cell foam, a resilient material produced from 100% neoprene polymer, is a versatile solution for many applications. From custom gaskets and seals to thermal insulation and packaging, closed cell foam offers exceptional durability and reliability, making it an indispensable choice across various industries.

 

The Manufacturing Process

Closed cell foam is crafted by subjecting a rubber compound, typically neoprene, to a gas, such as nitrogen, under high pressure. This process creates a unique cellular structure characterized by tightly sealed cells that do not allow air or liquids to pass through.

 

Closed Cell Foam Properties 

UL 94HF-1 Flame Rating: Most closed cell neoprene sponge products meet the UL 94HF-1 flame rating, ensuring fire safety and compliance with industry standards.

Chemical Resistance: Closed cell foam exhibits resistance against oils, grease, ozone, alkalis, and acids, making it suitable for use in harsh environments where exposure to chemicals is common.

Temperature Resistance: With the ability to withstand temperatures ranging from -70°F to 200°F, closed cell foam remains stable and effective in extreme temperatures. It also offers resistance against UV rays, ozone, and moisture.

Versatility: The unique internal structure of closed cell foam provides versatility, allowing it to be utilized in various applications, including thermal insulation, packaging, marine equipment, aerospace, construction, and industrial production.

 

Applications

Closed cell foam finds extensive use across a broad spectrum of industries and applications, including:

  • Custom Gaskets and Seals: Ideal for sealing applications, closed cell foam effectively reduces liquid and gas flow, making it suitable for industries where liquid resistance is critical, such as marine, HVAC, and automotive.
  • Thermal Insulation: Closed cell foam serves as an excellent thermal insulator, providing protection against heat loss or gain in electronic and computer components, clothing, metal products, and furniture.
  • Packaging: Closed cell foam is utilized as packaging material for fragile goods, providing cushioning and protection during transit.
  • Marine Equipment: Closed cell foam is used in marine applications for buoyancy and insulation properties, ensuring durability and reliability in harsh marine environments.
  • Aerospace: Closed cell foam serves as insulation and vibration-damping material in aerospace applications, providing protection and stability in aerospace components.
