Product details

ISNR 20 (Indian Standard Natural Rubber – Grade 20) is a widely used block rubber grade, offering good performance at a competitive price point. We source ISNR 20 only from well-known, BIS-certified manufacturers to ensure reliable quality for industrial applications.


Comparison with ISNR 10:


  • ISNR 20 has slightly higher ash and dirt content compared to ISNR 10, making it a more economical option.
  • Suitable for general-purpose products where ultra-high purity isn’t critical.
  • ISNR 10 is used for precision and high-spec applications, while ISNR 20 is ideal for large-volume, cost-sensitive production.


Comparison with RSS Grades:


  • Like ISNR 10, ISNR 20 is in block form, allowing easier handling and automation compared to RSS sheet forms (RSS 3/4/5).
  • Offers better consistency than RSS 4 or RSS 5, and is often preferred by manufacturers with large-scale production setups.


Why Manufacturers Choose ISNR 20:


  • Great for tires, rubber mats, footwear soles, and moulded items.
  • Balances quality and cost effectively.
  • Consistent supply and ease of processing in factory setups.
