Neoprene and polyethylene are part of the same synthetic family and share similar properties. Polyethylene is a product of the polymerization of ethane, and was first used during 1898 in Germany.
Polyethylene was actually produced by accident. The accident resulted in a smooth wax like substance that displayed remarkable qualities in a wide range of temperatures. The product had physical characteristics that allowed it to be shaped and moulded into components for a large range of applications usages.
By 1933, polyethylene went into mass production. It is believed that on a yearly basis, 60 million tons of polyethylene is produced, and utilized all over the globe. Products that are made from polyethylene include furniture, refrigerator doors, gaskets and more.
Neoprene and polyethylene gaskets belongs to the same synthetic family and both are considered equal regarding heat resistance. However, they have different properties which benefit certain applications.
Neoprene gaskets scored a slight edge over polyethylene as they are superior in the heat resistance, making them ideal for applications with extremely high temperatures for long periods of time. Polyethylene, on the other hand, is better suited for applications where temperatures are consistently lower.
