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.
