Ribbed Smoked Sheets (RSS)

Thailand is the world’s number one rubber producer. With its strategic location at the center of Southeast Asia and an abundance of natural rubber, it remains an attractive destination for investment in the rubber industry.

Not only is the country a regional vehicle production and export base for some of the world’s leading carmakers, the growing demand in the nation’s healthcare market and the strong government support for rubber and its supporting industries also makes it an ideal destination for foreign investors to set up manufacturing bases.



Ribbed smoked sheets are used in various industries due to their variety in the requirements on cleanliness and tear strength of the sheets. There are five major grades: RSS 1 to RSS 5. The difference in the grades is the result of the preparation of the coagulated field latex during the production of the Unsmoked Sheets. The sheets are selected and smoked at a controlled timing and temperature window to ensure that they are properly smoked without causing negative impact on the rubber properties. RSS grades still depend heavily on visual inspection, thus, there is a high probability of inconsistency in grading. Therefore, Thai Hua established a training program for our inspectors with periodic cross checks for their grading level to ensure that all our factory individuals are in sync.
