Cork Rubber Gasket
Both cork and rubber are known to be natural materials that are widely used in many industrial spheres. And what happens when these two materials are joined with resin? Then, we get a very durable and flexible material, cork rubber – which is not only a good insulator but also great for making gaskets for different purposes. Therefore, it is not surprising that today, the cork rubber gasket is one of those parts that require mass production. The need for different industries for these parts is growing every day. However, they are most commonly used in the automotive industry.
Today, cork rubber is most often used to make various types of seals that can differ in some of their features. They differ primarily in the size of the granules used in the production of such semi-rubber compounds. And where do we most often use cork rubber gaskets? Well, they are almost all around us. Cork rubber gaskets are known to be very effective seals that have exceptional oil resistance – but also serve to seal and protect against the penetration of other types of liquids. Therefore, we will see them on wine corks, but also the covers of electrical appliances, car valve covers, etc.
As we mentioned, the most common use of cork rubber gasket is related to the auto industry. We will see them at the gearbox, but also at the thermostat or the fuel and oil pump. This is primarily due to their protective ability – but also the fact that they can withstand high temperatures. However, when we talk about resistance to high temperatures, different types of cork rubber gaskets will withstand different temperatures or pressures to which they are exposed. Therefore, these parts are made according to certain standards – and their specifications are shown when purchasing these useful products.
