Polyurethane elastomers are prized for their unique combination of strength, flexibility, and durability, making them indispensable in a wide range of industrial applications. At the heart of many high-performance elastomer formulations lies Toluene Diisocyanate (TDI) 80/20, a critical chemical intermediate that dictates many of the material's final properties.

TDI 80/20, with its specific isomer ratio of 80% 2,4-TDI and 20% 2,6-TDI, is a powerful reactive chemical. When reacted with appropriate polyols, it forms the robust polymer chains that characterize polyurethane elastomers. These elastomers exhibit exceptional resistance to abrasion, tearing, and impact, alongside good load-bearing capabilities and a broad operating temperature range. This makes them ideal for components like industrial rollers, seals, gaskets, wheels, and even protective footwear.

For manufacturers aiming to produce superior PU elastomers, understanding the contribution of TDI 80/20 to the material's performance is crucial:

  • Reactivity Control: The 80/20 isomer mix provides a balance of reactivity that aids in achieving consistent processing cycles, essential for molding and extruding elastomer parts.
  • Mechanical Properties: TDI 80/20 contributes significantly to the tensile strength, elongation at break, and compression set resistance of the final elastomer product.
  • Chemical Resistance: Polyurethane elastomers derived from TDI 80/20 typically offer good resistance to oils, greases, and many solvents, enhancing their longevity in challenging environments.

When you decide to buy TDI 80/20 for your elastomer production, selecting the right supplier is as important as selecting the right polyol. A reputable manufacturer and supplier, such as NINGBO INNO PHARMCHEM CO.,LTD., will ensure you receive TDI 80/20 that meets strict specifications. Key considerations for sourcing include:
