Neoprene and polyethylene gaskets all belong to polychloroprene gasket[gasket?:gasket die cutting machine] which will stand up to a lot of heat. However, along with temperature factors, any proper evaluation of neoprene and polyethylene gaskets must also address such factors as operating pressure and shielding.
Because of the superior resistance to heat, the use of neoprene gaskets in situations where temperatures will be high for extended periods is desirable. Polyethylene gaskets by contrast work very well in situations where the temperatures will be consistently lower.
Neoprene and polyethylene gaskets each have their own place in the pecking order of working components. A neoprene gasket will work well in large engines, such as for cars, trucks, boats and airplanes. All these situations would require a gasket that could stand up to high temperatures as well as a great deal of pressure. A polyethylene gasket works well for sealing doors on appliances such as refrigerators and ovens, as a sealing lining around doors and windows, and as a seal on a lid or jar.
One crucial difference between neoprene and polyethylene gaskets is that neoprene is meant to provide a more or less permanent seal, while polyethylene provides a seal that can be broken and then be reestablished. Both neoprene and polyethylene gaskets play important roles in the home, the workplace, and in the production of many of the products we use every day. However, neoprene and polyethylene gaskets should not be thought of as interchangeable in all situations.
