What is the Industrial Purpose of Rubber Gasket?
Rubber gaskets are basically used to fill space between two objects so as to join them appropriately and avoid leakage of gas or liquid while under compression. We assume the only rubber gasket most of you can think of is that of the pressure cooker but mind you this is not the only place it is used.
Types of Rubber Gaskets and Their Use
Rubber gaskets are made using different rubber materials to suit the need of different industries. The rubber’s hardness, tensile strength, resistance to permanent indentation varies based on its material. Rubber material which is softer is less dense and more flexible. You can make a greater impression on the rubber material which is softer. Rubber sheets with greater hardness are denser and less flexible. They are also heavier. The tensile strength of the rubber determines the stress it can undergo when stretched. The rubber material is chosen based on the application of the Gaskets manufacturer

and the weather conditions and chemicals it shall be exposed to.
Here are some of the commonly used rubber gasket materials:
Silicone: It is highly resistant to UV rays, ozone and oxygen. It has a working temperature greater than 450 degrees Fahrenheit. It can resist good amount of pressure but does not possess good tear strength. It is best suited for automobiles and electrical appliances.
Neoprene: Neoprene rubber provides three gasket forms. These are homogenous, diaphragm and sponge. This type of rubber gasket can be compressed easily. It offers good resistance to weather, oil and ozone and moderate resistance to petroleum products. It makes for perfect sealing for refrigeration fluids. It is also used in air conditioners.
Polytetrafluoroethylene (PTFE): It offers high resistance to heat. It is also highly resistant to water. It is mostly used in equipments that are constantly exposed to water. O-rings are usually made of PTFE
Ethylene Propylene Diene Monomer (EPDM): Rubber gasket made with this material is resistant to grease, oils and UV rays. It is available in two durometers. One of which is moderately flexible while the other is hard. It is highly resistant to corrosive liquids. It has a black plate finish and is fit to be used in outside applications.
