SVR 3L: Produced from field latex, it is used in performance tyres, industrial rollers and other applications requiring high quality, light coloured rubber. SVR 3L is sometimes used as an alternative to TSR 5 grade rubbers because its lower viscosity enables quicker mixing time.
SVR 10: A general purpose rubber made from field coagulum, it is used in the manufacture of tyres, inner tubes, extruded hoses and quality footwear items.
SVR 20: Also a general purpose rubber made from field coagulum, it is used in the manufacture of tyre products and other less-critical applications such as extruded hoses, rubber mats, conveyor belts, footwear and molded goods.
Application:
Widely used in performance tyres, industrial rollers and other applications requiring high quality.
