which is also known as Block Rubber. It can be produced from both field latex and field coagulum of NR(cuplump) or a blend of both and is graded accordingly to precise technical parametres such as content of Dirt , Ash , Nitrogen, Volatile matter and its properties such as Wallace Plasticity(PO) and Plasticity Retention Index. It has good processing characteristics and physical properties. Major TSR schemes include Standard Thai Rubber (STR), Standard Indonesian Rubber (SIR), Standard Malaysian Rubber (SMR) and Standard Vietnamese Rubber (SVR).
is commonly known as RSS. It is made from coagulated latex sheet . The grades of RSS are determined and classified by visual examination and experience which are graded into RSS1 to RSS5 according to elasticity, color and purity on the basic as per International Standard of IRQPC (Green Book).
is derived from field latex and it's processed using centrifuge methods. It contains 60 percents of Dry Rubber Content(DRC). Types of latex can be obtained by the different amount used of preserved ammonia such as High Ammonia(HA) and Low Ammonia(LA/LATZ). The latex concentrated are market under strict technical specification, base on dry rubber content, non-rubber solid, alkalinity, mechanical stability and other parameter relating to ISO2504 specification.
