Neoprene and polyethylene gaskets are similar in many ways, but both have their very own place in the hierarchy of working components. A neoprene gasket works ideally on large engines, as in cars, trucks, boats and aeroplanes, whereas all of them require a gasket that can withstand high temperatures as well as a huge amount of pressure.
The polyethylene gasket on the other hand works perfectly well for things such as sealing doors on appliances such as refrigerators, ovens, and as a sealant around doors and windows, and as a seal on things as simple as a lid or jar.
History and Usage
- Originally a creation of the DuPont Corporation, neoprene is a member of the polychloroprene group of synthetic rubber elements.
- It can withstand a broad range of temperatures, and is frequently utilised in the manufacture of things such as wetsuits, electrical insulation, car hoses and fan belts, and gaskets.
- Polyethylene is also a fabricated compound and is in this case a member of the polymer family.
- Created via the polymerisation of ethane, a basic alkaline, polyethylene was first discovered purely by accident during an experiment.
- The resulting waxy compound rapidly demonstrated its ability to be moulded into useable products that would hold themselves up well in high temperatures.
- Some sources state that as much as 60 million tons of polyethylene is made annually and utilised for a whole range of sealing products, which rangeall the way from resin furniture to gaskets for use in refrigerator doors.
- When one compares neoprene and polyethylene gaskets, it is of importance to make a note that both will stand up to lots of heat.
- Along with all of the aspects of temperature, however, any real evaluation of these gaskets must also address things such as operating pressure and shielding.
- The underlying duty for gaskets is to prohibit fluid or gas leaks between two or more surfaces that touch.
- Due to the superior resistance to heat, neoprene gaskets are commonly put into use in situations where the temperature will be high for very long periods of time.
- Polyethylene gaskets, on the other hand, can work extremely well in any type of situation where the temperatures are consistently lower.
- This places the use of polyethylene in the same classification as polypropylene gaskets, which necessitate a lot of heat to produce the material and will work just as well in lower to moderate range temperatures.
- One vital differential between neoprene and polyethylene gaskets is that neoprene is designed to provide a somewhat permanent type of seal, whereas polyethylene provides the kind of seal that can be broken and then be renewed.
Both of these materials are major players in our homes, in various workplaces, and in the production of so many of the products that all of us use every single day. However, they are not interchangeable in every situation. And how many of these products have you used today already?!
