Closed cell sponge rubber can be formulated into several different elastomeric materials in a variety of densities. The most common materials are Neoprene/EPDM/SBR blend, Neoprene, EPDM, and Silicone. Sponge rubber can be specified in low, medium, or high density firmness’s. It is a highly flexible material that can adapt to seal almost any surface application when used with pressure sensitive adhesives or with Heat Activated Tape Systems (HATS). Closed cell sponge rubber, or expanded rubber, is composed of individual cells that are a lot like balloons; they hold in gas and do not allow moisture to penetrate their walls so long as the cell walls do not burst. The cells in closed cell sponge rubbers are not interconnecting, meaning they do not allow air or water to wick through the sponge at low pressures.

This rubber, a copolymer of ethylene and propylene, has outstanding resistance to aging, weathering, ozone, oxygen, and many chemicals, as well as excellent temperature stability and steam and water resistance. EPDM also shows an excellent resistance to gas permeability and aging due to steam exposure. It is an excellent polymer to use in high temperature applications as it is heat resistant up to 350Â°F. Ethylene Propylene provides poor resistance to oil and solvents; however it is fairly good in its resistance to ketones and alcohols. EPDM is not recommended for usage in food applications or those that expose it to aromatic hydrocarbons. EPDM would be one of the recommended polymers to use in a bleach application!

Foam rubber is found in a wide range of applications, from cushioning in automobile seats and furniture to insulation in walls and appliances to soles and heels in footwear. Foams are made by forming gas bubbles in a plastic mixture, with the use of a blowing agent. Foam manufacture is either a continuous process for making laminate or slab stock or a batch process for making various shapes by cutting or molding. Rubber’s foam rubber products offer cost-effective sealing and cushioning solutions.

- Automotive trim
- Chemical resistance properties for fire & burning, ultraviolet uses etc.
- Shoe soling
- Insulations in refrigerators, freezers, buildings, transport vehicles
Natural rubber is an elastomer that was originally derived from milky latex found in the sap of some plants. The purified form of natural rubber is the chemical polyisoprene, which can also be produced synthetically. Natural rubber is used extensively in many applications and products, as is synthetic rubber. Natural rubber is an ideal polymer for dynamic or static engineering applications. Natural rubber cannot compare with many synthetics for heat aging and resistance to sunlight, oxygen, ozone, solvents or oil.
- Excellent dynamic properties with a low hysteresis loss
- Good low temperature properties
- Strong bonding to metal parts
- High resistance to tear and abrasion
- Ease of processing
- Hose and tubing
- Vibration isolators
- Shock mounts
- Electrical components
- Extremely resilient elastomer
This rubber is a polymer of chloroprene and has several valuable properties and works well in applications requiring resistance to gasoline, sunlight, ozone, and oxidation. Neoprene Rubber, also known as neoprene polychloroprene, is an extremely versatile synthetic rubber with more than 75 years of proven performance. It was the world’s first synthetic elastomer with oil resistance and is still the primary choice in a range of applications. In the automotive world, neoprene is used for many under hood and underbody parts that require a reasonably priced, mid- performance polymer with a good all-around balance of performance properties.
- Versatile with oil resistance
- Sunlight & Ozone resistance
- Resistance to oxidation
- Good all around properties
