01Overview
Why manufacturers choose TSNR 20
It is widely used in tire manufacturing, conveyor belts, industrial hoses and mechanical components thanks to its excellent strength, abrasion resistance and flexibility. Processed under strict industry standards, TSNR 20 ensures reliable performance across demanding applications while supporting sustainable, eco-friendly production.
Exceptional strength & elasticity
TSNR 20 offers exceptional tensile strength, making it highly resistant to tearing, abrasion and deformation. Its natural elasticity allows it to withstand heavy loads and extreme conditions — ideal for industrial and automotive applications.
Consistent, standardized quality
Manufactured under rigorous quality guidelines, TSNR 20 ensures uniformity in composition, moisture content and impurity levels. This guarantees consistent performance in critical applications, reducing defects and enhancing product reliability.
With its consistent quality and high-performance properties, TSNR 20 is a preferred choice for industries demanding reliable, long-lasting natural rubber.
02Typical specification limits
TSNR 20 at a glance
