Product description
Mondur 1434 is a low to medium functionality polymeric diphenylmethane diisocyanate (PMDI) with a moderately high 2,4’-MDI isomer content.
Applications
Mondur 1434 is used in a box pour process to produce sheets of formable rigid foam. The foam sheet is used as the lightweight core material for composite PU headliners. As with any product, use of Mondur 1434 Isocyanate in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Storage
Mondur 1434 must be stored in tightly closed containers and protected from contamination with moisture and foreign materials, which can adversely affect processing. It will react slowly with water to form polyureas and liberate carbon dioxide gas, which may cause sealed containers to expand and rupture. Storage temperatures should be maintained between 10° to 30°C (50° to 86°F).
