Trade Name(s):

Too Many to list

ASTM D1418 Designation:SBR
Standard Colour:Black

Also known as Buna S, or GR-S (Government Rubber-Styrene), Styrene Butadiene was the elastomer substituted for Natural Rubber during World War II. Compounded properties are similar to those of Natural Rubber with generally better abrasion resistance, but with poorer fatigue resistance.

Key Use(s):

Isolation dampeners.

Temperature Range:
Standard Compound:-45°C (-50°F) to 100°C (212°F) – Dry Heat Only
Hardness (Shore A):40 to 90

The main use for Styrene Butadiene today is in the manufacture of automobile tyres.


SBR is not recommended for exposure to petroleum oils, most hydrocarbons, strong acids, or ozone. It is very weak unless reinforcing fillers are incorporated.

This material is seldom used in modern sealing applications. It has been replaced by better performing materials.
