NAMRUB 20 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 characteristics of NAMRUB 20 reduces the mixing period considerably making it very cost effective.
