Ribbed Smoked Sheets (RSS)
Ribbed Smoked Sheets (RSS) are still widely used in different industries, especially tyre business. Unsmoked Sheets are collected from local farmers. The sheets are cleaned and smoked in controlled temperature with technical supervision. The smoked sheets then are classified by visual inspection from well-trained staff into five grades.
Grades :
RSS-1 / RSS-2 / RSS-3 / RSS-4 / RSS-5

Concentrated Latex
Latex is collected from rubber trees with controlled care. Latex is rubber material in pure form of collection. It is preserved by added chemicals and centrifuged. We then obtain a concentrated latex of 60% DRC (dry rubber content). Chemical added during the process is Ammonia to preserve the latex content from coagulation
Grades :
60% DRC Concentrated High Ammonia Latex (HA)
60% DRC Concentrated Medium Ammonia Latex (MA)
60% DRC Concentrated Low Ammonia Latex (LA)
Packaging :
In Drums 205 Kg.

Green Book Standard for Ribbed Smoked Sheets (RSS)
NR in sheet forms are the oldest and the most popular type. Being the simplest and easiest to produce on a small sacle, small holder's rubber in most of the countries are processed and marketed as sheet rubber. Two types of sheet Rubbers are produced and marketed in the international market, namely the Ribbed smoked sheets(RSS) and the Air Dried Sheets(ADS). Among these two types, Ribbed smoked sheet is the most popular and is available for volume consumption.
Ribbed smoked sheets are marketed based on visual assessment of quality. To establish acceptable grades for commercial purposes, the international Rubber Quality and Packing conference, have stipulated the grade description and the details are given in the Green Book.
THE INTERNATIONAL GRADE DESCRIPTIONS FOR RSS
Only deliberately coagulated rubber latex processed into rubber sheets, properly dried and smoked can be used in making RSS. The following prohibitions are also applicable to the RSS grade.
Prior to grading RSS, the sheets are separated, inspected and any blemishes are removed by cutting with a pair of scissors.
