Standard Malaysian GP (SMRGP)
This is another viscosity-controlled natural rubber (66 +/- 6 mooney viscosity) that is extremely price competitive with specifications similar to Standard Malaysian Rubber 10 (SMR 10). Thus, using the Standard Malaysian Rubber GP (SMR GP) eliminates the price advantage of Standard Malaysian Rubber 10 (SMR 10) over Standard Malaysian Rubber CV60 (SMR CV60). You then have the cost of Standard Malaysian 10 (SMR 10) with the processability of a CV60. One-pass mixing with Standard Malaysian Rubber GP (SMR GP) bale rubber is excellent compared to bale Standard Malaysian Rubber 10 (SMR 10) one-pass mixed. Carbon black dispersion is much better; mooney viscosity is lower; and mooney scorch is lengthened. A single-passed batch was run using Standard Malaysian Rubber GP (SMR GP) and one with Standard Malaysian Rubber 10 (SMR 10) with the following results. Standard Malaysian Rubber grade SMR 10 and Standard Malaysian Rubber 20 (SMR 20) are technically specified natural rubber products derived from field coagulum or cup lump. These grades are commonly used in tire and automotive industry as well as in general moulded and extruded rubber products. Our Standard Malaysian Rubber (SMR) rubber is of the best quality due to our stringent quality control of the raw material starting right from our own plantation and processed with customer’s satisfaction in mind.
