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. Block Rubber 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 (PRI). It has good processing characteristics and physical properties. Our group factories are qualified under the major TSR schemes including 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 RSS1 to RSS5 according to elasticity, color and purity on the basic as per International Standard of IRQPC (Green Book). These grades are determined and classified through visual examination by experienced sorters and inspectors.
is derived from field latex and it is processed using centrifuge methods. It contains 60% of Dry Rubber Content (DRC). Types of latex are differentiated by varying the amount used of preserved ammonia used such as High Ammonia (HA) and Low Ammonia (LA/LATZ). The concentrated latex are marketed under strict technical specification, based on dry rubber content, non-rubber solid, alkalinity, mechanical stability and other parameters relating to ISO2504 specification.
