With technical expertise, eco-friendly practices, and professional service, we are committed to providing stable, high-performance rubber and building long-term, reliable partnerships worldwide.

What RSS 1 Stands For

Ribbed: The rubber sheets are pressed into a ribbed (grooved) form, which improves drying efficiency and prevents the sheets from sticking together.

Smoked: The sheets are dried in traditional smokehouses, a process that helps preserve the rubber, prevents mold, and gives the sheets their distinctive brownish color.

Sheet: The final product is shaped into flat sheets, making it easier to grade, package, and transport.

Grade 1: This designation represents the highest visual quality in the RSS family, with the fewest imperfections such as oxidized spots, air bubbles, or foreign matter.
