An integral part of our custom sponge and foam gaskets and seals product line, A.J. Rubber & Sponge Ltd.’s neoprene sponge gaskets are designed to stay in one place and provide long-lasting permanent sealing for virtually any environment that is exposed to a wide range of temperatures and enormous pressures. A variety of commercial and industrial organizations depend on our neoprene sponge gaskets for durability and stability:

• Oil & gas companies
• Automotive manufacturers
• Clothing producers
• Electronics producers
• Medical equipment manufacturers
• Aviation & aerospace
• Military & department of defense
• Engine assemblers (cars, trucks, buses, trailers, watercraft, airplane)
• And many others

The synthetic rubber (neoprene) that is used to manufacture our neoprene sponge gaskets has many advantageous characteristics, including:

• Temperature operating ranges of -56.7°C to 93.3°C (-70° F to + 200° F)
• Superior burning and heat resistance (more so than rubbers that are composed exclusively of hydrocarbon chains)
• Resistant to extreme elements such as ozone, ultraviolet light radiation, direct sunlight, rain, snow, hail, sleet or other unstable forces
• Resists the effects of natural and synthetic oils as well as acid, gasoline and other chemicals
• Resistant to damage or tears caused by twisting and/or flexing
• Suitable for long term outdoor use such as in electrical enclosures or as a weather stripping material

A.J. Rubber & Sponge Ltd. is capable of kiss cutting, die cutting, and applying pressure sensitive adhesive (PSA) to our neoprene sponge gaskets.
