Good temperature resistance.


This type of synthetic rubber shows moderate resistance to tearing, ozone and weathering due to its unsaturated molecular chains. The SBR rubber has good chemical resistance to inorganic chemicals, but not to oxidising acids, limited to mineral acids, and it is not suitable for organic liquids in general.

This material is perfect for sealing gaskets.

The standard styrene-butadiene or SBR rubber is black with 65 Shore A hardness.
