Rubber SBR

SBR (butadiene-styrene) rubber has good mechanical properties with a good breaking load value, permanent deformation strength and elastic recovery, and good fatigue, tear and wear resistance. Furthermore, non-toxic products can be created from SBR.

It also possesses good dielectric properties and is compatible with silicone oils, water and dilute solutions of acids, bases and salts.

It shows, however, poor resistance to oxygen, ozone, UV radiation and oxidising agents. It is also incompatible with mineral, vegetable and animal oils, aliphatic, aromatic and chlorinated hydrocarbons.

SBR rubbers are mainly used in the tyre industry to make various parts.
