WELCOME TO THE WORLD OF RUBBER

Suppliers of high-quality natural rubber raw materials, primarily focusing on Ribbed Smoked Sheets (RSS) in RSS3, RSS4, and RSS5 grades.

Kerala’s favorable weather conditions play a pivotal role in the successful cultivation of rubber. The region’s average annual rainfall of around 3000 mm, combined with warm temperatures, provides an ideal environment for rubber trees to thrive. The sandy-loam soil found in Kerala enhances drainage and is rich in nutrients, supporting robust tree growth.

The traditional agricultural practices in Kerala, passed down through generations, are integral to this success. Local growers have developed expert techniques for tapping rubber trees, ensuring optimal latex extraction to get the best quality latex. Their experience helps in maintaining tree health, balancing yield and sustainability. By fostering these traditional methods and leveraging the natural advantages of Kerala’s climate and soil, the region continues to produce high-quality Ribbed Smoked Sheets (RSS) that meet global standards.

What we do

Comprehensive rubber solutions from grading to delivery, tailored to meet your needs with precision and reliability.

Ribbed Smoked Sheets (RSS) are coagulated rubber sheets processed from fresh field latex sourced from well managed rubber plantations adopting modern processing methods. The grades available are shown in the table. The higher grades RSS 1x to RSS 3 are mainly used for manufacture of products for medical, pharmaceutical and engineering. The lower grades of RSS 4 and 5 are generally used for the manufacture of automobile tyres, re-treading materials and all other general products. RSS 3 and RSS 4 are the preferred raw material for radial tyres. Quality of Ribbed Smoked Sheets is ascertained as laid down in Green Book Standards.

In India, RSS grades are packed as 50kg bales in polythene cover and as 110kg crates as per the requirements of the buyer. Ribbed Smoked Sheets are graded according to the standards as per IS – 15361-2003 by visual comparison method. Normally this is done by observation of sheets held against light, when the obvious defects become apparent.

Cluster groups formed among rubber farmers in India, popularly known as “Rubber Producers Societies (RPS) are involved in the production of high quality grades in their group processing centres for domestic and world markets. High grade sheets are produced in individual farms as well.

Domestically produced RSS rubber grades are in good demand for tyres and other product manufacture indicating their quality and market acceptability.
