General Information

SBR is an economic, general purpose elastomer. Also known as Buna-S, it was originally developed to replace natural rubber in the manufacture of tyres. This commodity material is generally used when there is no special need for resistance to heat or ageing. It resists water, saline solutions and weak acids. It also has very good resistance to fatigue, but is not very resistant to chemical agents, except polar ones, such as alcohols and ketones. It is likewise suitable for use in contact with car brake fluid; however, it is not resistant to petroleum-based fluids or oils. It performs twice as well at low temperatures.

Manguitos

We manufacture vulcanised sleeves in any type of rubber (SBR, NBR, EPDM, silicone, Viton, brown natural rubber, etc.) using a hot-vulcanising technique to form a bevel joint, which is more flexible, long-lasting and smoother than other joints.
