There are a number of industries which make use of closed cell sponge rubber, and its versatility means it is suited to a wide range of applications within each:
Heating, ventilation and air conditioning (HVAC) systems, seals and gaskets, carburettor gaskets, noise reduction systems, vibration suppressions, miscellaneous pads, wiring harness gaskets, interior and exterior lighting gaskets, aerial gaskets, seals on vehicle doors and boots
Appliances and White Goods
Seals on washers and dryers, seals and gaskets on air conditioning units, seal on refrigerators, mounting pads for humidifiers, gaskets for vacuum cleaners, padding for sound equipment, vibration pads for stereo speakers, gaskets for dishwashers, gaskets for lighting equipment, gaskets for electric signs.
Closure seals for metal buildings, curing blankets for concrete, seals for electrical boxes, seals for miscellaneous receptacles, seals for doors and windows, weather stripping for use with light fittings, wrapping for pipes, expansion joints for concrete.
Lighting, electrical enclosures, electrical control panels and HVAC systems.
Seal to protect against air, dust and water to regulatory standards in applications such as fire and security systems, miscellaneous weather stripping and gasket applications, ductwork applications.
Transportation, Marine and Rail
Seals for hatches, miscellaneous weather stripping, cushioning for conveyor belts, repairs on rail cars, miscellaneous oil seals.
Closed Cell Neoprene Sponge Rubber
Closed cell neoprene rubber is produced using 100% neoprene polymer. The majority of products which use it comply with the UL 94HF-1 flame rating. This means that they can operate continuously within temperatures ranging from -40°F to 158°F, and also temporarily withstand temperatures of up to 200°F. The very best products created using closed cell neoprene sponge are resistant to light oil contact and corrosives such as ozone, alkalis and acids. This property makes them the ideal solution for a wide range of door gaskets.
Closed Cell Blended Sponge Rubber
Closed cell blended sponge rubber is produced using a blend of neoprene, SBR and EPDM. It is the grade of closed cell sponge most commonly utilised when commercially producing general purpose sponge gaskets. Products using this material usually adhere to UL 94HF-1 regulations and can operate in temperatures as low as -70°F without cracking. It should be noted that these products will not offer the same level of oil resistance as those made from 100% neoprene sponge.
Closed Cell EPDM Sponge Rubber
Products made using closed cell EPDM sponge are not resistant to oil or fuels and will not meet the UL 94HF-1 regulations unless bolstered with additives. In spite of this, they offer superior resistance to external environmental factors such as ozone, indirect sunlight and water, when compared to neoprene.
PVC Nitrile has a close cell composition which offers a natural vapour barrier and makes it the best material for acoustic and thermal insulation applications. It comes packaged as sheets, coils or tubes and is the ideal solution for applications such as containing heat emissions within the engine room of a ship, creating moisture and thermal barriers in vehicles such as coaches and buses, and insulating hot pipes. These are just a few examples of the uses this versatile material can be put to.
