Is SBR a good gasket material?

What is SBR?

SBR, commonly referred to as plain rubber or black rubber, is the most widely produced synthetic rubber in the world and is commonly used to make gaskets for non-critical applications. SBR gaskets are usually chosen when cost is the main criterion, as it is the cheapest rubber available on the market. If the application you need a gasket for has particular technical requirements, SBR is most likely not the most suitable material.

Each rubber has its own characteristics, and these must match the needs of each application. If the gaskets will be exposed to the weather, use EPDM gaskets. If they will be in contact with oils or greases, ask for nitrile gaskets. If they will work with petrol or crude oil, you will need Viton® gaskets. If they are for food or pharmaceutical applications, what you need are silicone gaskets certified for these uses. And we could go on with an endless list of specific needs and the right rubber for each one: Hypalon gaskets, natural rubber gaskets, neoprene gaskets, …
