The TSR 10, 20, 10CV and 20CV grades, derived from cup-lump, are dark and durable rubbers, as well as the most economical TSR grades. The TSR CV50 and CV60 rubbers, produced with field latex and classified according to the Mooney viscosity scale (CV=Constant Viscosity), are light and soft rubbers, less economical due to the higher processing costs. The TSR L grade has the lightest color, classified according to the Lovibond scale.
