Synthetic Rubber for Rubber Gaskets, Rubber Seals and More

Styrene Butadiene Rubber (SBR), or synthetic rubber, is a non-oil resistant, low-cost material that can be used in the production of several rubber products. It has properties similar to natural rubber, but with greater wear, water and abrasion resistance.

Natural rubber vs synthetic rubber

Compared to natural rubber, the advantages of synthetic rubber include its excellent abrasion resistance and ability to adhere to metals, making it a great option for rubber gaskets, seals and other products. Synthetic rubber also excels in extreme temperatures due to good heat resistance and heat-aging qualities. However, it is not recommended to use synthetic rubber in applications that involve ozone, strong acids, oils, greases, fats and most hydrocarbons.

What is synthetic rubber used for?

When you need a low-cost alternative to natural rubber, opt for synthetic. The synthetic material can be used in the production of several rubber applications, including:
