SMR 10 is  a  technically  specified  natural  rubber  with   excellent processing characteristics and good physical properties.  It’s high green strength, tack and cohesive properties makes it an  ideal choice in the manufacture of  high performance  passenger  and truck tyres.The low viscosity and easier mixing characteristic of SMR 10  reduces  the mixing  period  considerably  making it  very cost effective.
