A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Dicyclohexylmethane-4,4'-diisocyanate (CAS 5124-30-1), the hydrogenated analog of MDI, is a cycloaliphatic diisocyanate used to make light-stable polyurethanes. Industry references record its primary use in flexible coatings and polyurethane elastomers and in urethane products that do not yellow on light exposure. Supplied as a bulk isocyanate intermediate.
Frequently Asked Questions
What is H12MDI?
H12MDI is dicyclohexylmethane-4,4'-diisocyanate (CAS 5124-30-1, C15H22N2O2), the hydrogenated (cycloaliphatic) analog of MDI. It is used to make light-stable polyurethanes that do not yellow on light exposure. RawSource supplies it as a bulk isocyanate intermediate.
What is H12MDI used for?
It is used as the isocyanate component in light-stable, non-yellowing polyurethane products, including flexible polyurethane coating systems and polyurethane elastomers. Its cycloaliphatic structure gives the resulting PU resistance to light-induced yellowing.
What is methylene bis(4-cyclohexyl isocyanate)?
That is another name for the same material — dicyclohexylmethane-4,4'-diisocyanate, or H12MDI (CAS 5124-30-1). It is the saturated, ring-hydrogenated counterpart of aromatic MDI.
What is the UN number and HS code for H12MDI?
It ships under UN 2206 (1,1-methylene bis(4-isocyanatocyclohexane)) and classifies under HS 2929.10 (isocyanates). Transport requirements follow the SDS, which RawSource supplies with every order; confirm tariff treatment with your customs broker.
What bulk packaging is available for H12MDI?
H12MDI is supplied as a bulk isocyanate intermediate in moisture-protected drums and totes. MOQ, lead time, and pricing are quote-based — request a bulk quote with your target volume; an SDS and CoA accompany the order and the SDS should be reviewed before handling.
