The gaskets are made using neoprene rubber which varies in thickness, hardness and overall resistive capacity.
Neoprene is versatile & often used to seal cryogenic applications.
Neoprene Gaskets – The gaskets are made using neoprene rubber which varies in thickness, hardness and overall resistive capacity. They are typically black in color and can also be availed with or without adhesive backing.
Neoprene rubber gaskets have copious amounts of properties, all of which make it a very useful material. The capabilities of neoprene has made it one of the most common rubber gaskets to use. Neoprene is a trade name of DuPont, developed in the 1930’s by DuPont scientists of the DuPont laboratories. This synthetic rubber was developed as a general purpose compound.
Neoprene is elastic, water proof, and moderately resistant to chemicals. Neoprene has been called the “best and final” of synthetic rubbers because of the wide range of benefits it offers. Neoprene rubber can be found in things such as wetsuits, all the way to laboratory equipment protectors. Neoprene gasket materials have the ability to withstand harsh environments and can be purchased at a cost that won’t break the bank, making it a favorite for gasket materials. It should be noted that gaskets are not solely created from rubber, but some from metal as well.
Metal is a very durable material in applications with tremendous temperature, however a major disadvantage to metal gaskets is they are ineffective for most mediums. The hardness of metal restricts these gaskets to being used only with materials harder than metal, otherwise the gaskets will fail to compress sufficiently enough to create an air tight seal.
Alternatively, rubber gasket sheets are a softer compound that can produce air tight seals with a large myriad of mediums because rubber does not require as much pressure to compree as metal. The creation of rubber was not to replace metal parts, but more so to help save metallic parts that come together in machinery and industry.
Neoprene gasket material is made from a blend of Styrene Butadiene Rubber(SBR) and CR. Neoprene is a manmade synthetic rubber developed to tolerate chemicals well. Neoprene gasket material is frequently used to protect laboratory equipment and other chemical applications because of its superior resistance to hydrogen gas, natural gas, salt/sea water,acetic acids, oils, and more. An additional benefit of neoprene is it creates flexible rubber gasketing to fit a greater amount of surfaces than other gaskets. Neoprene gaskets are uniquely designed to be resistant to oils and withstand high temperatures for long durations of time, making them the preferred gasket material for large engines, such as cars, trucks, and airplanes.
Neoprene is not only resistant to chemicals but is also waterproof. This capability makes it the ideal material for rubber water seals. Although the majority of rubber gasket sheets are water resistant, neoprene is the #1 material for water applications. The flexibility and durability of neoprene makes it the perfect rubber water seal because it forms air tight seals for underwater drainage systems that contain hazardous materials. This will guarantee that no leakages will occur, while removing the concern that they will corrode because of their ability to resist chemicals and water.
Neoprene is not dense and weights approximately 1 1/4 lbs. per 1/8″ in a standard durometer of 60. Neoprene gasket material is a great match for weight-conscious applications because it does not add a vast amount of additional weight onto products. Neoprene is the ultimate general purpose rubber, as you can find it in space shuttles as well as underwater pipe systems. It can be used in numerous applications because of its wide range of resistances. The ability to tolerate extremely high temperatures, resist chemicals against an abundance of oils & greases, and remain waterproof for any underwater applications has made this flexible rubber gasket material the most optimal solution to any gasketing needs. The endless list of benefits proves that neoprene gasket material is one of the most versitile and preferred rubber shets used for gaskets.
Neoprene has outstanding properties that make it perfect for several infdustries that require a very specific material given the applications.
