Sponge Rubber Part Fabricator

Sponge Rubber Fabrication

A leak can cause higher energy bills at home, reduced engine performance on the road and contamination of vital processes on the manufacturing floor. Eliminate unwanted gaps at your application with reliable sponge rubber products from Foamcraft USA.

Sponge rubber is rubber manufactured with a foaming agent to create perforated air-filled pockets. Lightweight and buoyant, it offers superior cushioning, thermal and acoustical insulation and impact dampening characteristics. Commonly known as cellular or foam rubber, it’s available in open-cell and closed-cell designs.

Open-Cell Sponge Rubber

Open-cell sponge rubber is calendared and injected with gas to create a cellular, forgiving design. It’s often manufactured in rolls from silicone or other polymers such as neoprene, EPDM, and nitrile. Capable of compressing and recovering quickly, open-cell sponge rubber seals against gases at low pressures, repels moisture and is highly cushioned. Other characteristics include resistance to acids, oils, ozone, oxidation, and light sunlight. Exact properties depend upon the polymer type used. Common uses for open-cell sponge rubber include:

  • die-cut parts
  • gaskets & seals
  • insulation
  • weather stripping
  • soundproofing
  • vibration dampening
  • filtration

Closed-Cell Sponge Rubber

Closed-cell sponge rubber creates an airtight and watertight seal at low pressures and has high flexibility and compression capabilities. It’s physically tough, resistant to burning, can withstand both hot and cold temperatures, and remains unaffected by contact with many oils and chemicals. Often manufactured from neoprene, closed-cell sponge rubber can conform and seal most surfaces. Common uses for closed-cell sponge rubber include:

  • die-cut parts
  • gaskets and seals
  • insulation and weather stripping
  • sound-proofing
  • vibration dampening
  • filtration

A versatile rubber product, sponge rubber can be manufactured in a wide array of thicknesses, densities, hardnesses and resistance properties by customizing the chosen mixture of foaming additives and catalysts. Our team can cut sponge rubber into sheets of a specified thickness or fabricate the product into the desired shape, piece or block using die, compression or contour cutting methods. Let us know your objectives and requirements, and our expert team will help identify, engineer and fabricate the best sponge rubber foam solution to meet your needs.
