Rubber seals form an important part of every production process. If they fail, the damage, not only to property, can be extensive. That is why the demands on their quality and lifetime are high.  

There is a wide variety of rubber seals available on the market, and they are used in different machines and industrial applications. For that reason, the materials they are made from also vary.

Which materials are they made from?

The most widely used material is technical/industrial rubber (usually referred to as EPDM), which is very resilient. Thanks to various additives it is weatherproof; it can withstand abrasion, but also high temperatures or corrosive substances.

Other materials can be:
