SBR rubber

SBR rubber

General characteristics

Only using reinforcing fillers, SBR vulcanizates have the same mechanical characteristics as natural rubber; however, they have a better resistance to abrasion, high temperatures and aging, but a lower elasticity and flexibility at low temperatures.

  • Resistance to heat: up to a maximum of 100°C. With the prolonged action of high temperatures they harden but do not soften like natural rubbers;
  • Resistance to low temperatures: down to ca. -50°C;
  • Electrical characteristics: good insulating power for correctly formulated compounds;
  • Gas permeability: high, but less than natural rubber. This use is in any case not recommended;
  • Chemical resistance: not particularly performing.

Fields of application

Almost 2/3 of the entire global production of SBR is destined to the tire sector. The rest is used for the production of various articles such as soles for shoes, coverings for cables, gaskets (e.g. for glycol-based brake fluids), tubes, coatings for cylinders, conveyor belts, flooring, mats, and household items.
