STR is a new process of rubber developing from natural rubber to technical specified rubber. It has been introduced in Thailand since 1968. The ability to measure and control the various physical aspects and characteristics of the baled Standard Rubber has brought about a major change in the rubber industry. STR are types of rubber grade which are packed in blocks. We offers STR10, STR20, STR10CV, STR20CV, STR20COMPOUND (SBR and Carbon Black).
