For procurement professionals and R&D scientists in the chemical industry, making informed purchasing decisions about raw materials is crucial. Bis(4-isocyanatocyclohexyl)methane (CAS 5124-30-1), often abbreviated as HMDI or Hydrogenated MDI, is a high-value aliphatic diisocyanate essential for producing advanced polyurethanes. This guide aims to equip buyers with the knowledge to select and source this critical component effectively, emphasizing the benefits of partnering with a trusted supplier like NINGBO INNO PHARMCHEM.

What is Bis(4-isocyanatocyclohexyl)methane (HMDI)?

HMDI is an aliphatic diisocyanate known for its saturated cycloaliphatic structure. This key characteristic differentiates it from aromatic diisocyanates and is the source of its superior performance attributes:

  • UV Stability: Unlike aromatic isocyanates, HMDI does not yellow or degrade under UV light. This makes it ideal for applications where color retention and aesthetic appeal are critical over long periods.
  • Weather Resistance: HMDI imparts excellent durability against moisture, chemicals, and general environmental wear, ensuring the longevity of polyurethane products in demanding conditions.
  • Mechanical Strength: It contributes to polyurethanes with high tensile strength, good flexibility, and excellent abrasion resistance, suitable for robust applications.
  • Versatility: HMDI serves as a key building block for high-performance coatings, adhesives, sealants, and elastomers.

Key Applications for HMDI:

When you buy HMDI, you are investing in materials that excel in:

  • Coatings: Automotive clear coats, industrial protective finishes, and architectural coatings benefit from HMDI's non-yellowing and weather-resistant properties.
  • Elastomers: Manufacturing durable TPUs (thermoplastic polyurethanes) and cast elastomers for applications requiring high resilience, flexibility, and resistance to wear.
  • Adhesives and Sealants: Creating robust, weather-resistant bonds and seals for construction, automotive, and industrial use.
  • Fibers: Producing high-performance synthetic fibers.
