Categories:	Polymer; Thermoset; Polyurethane, TS
Material Notes:	Mondur MR 5 is a low to medium functionality polymeric diphenylmethane diisocyanate (pMDI) containing a relatively high level of pure (monomeric) MDI. Properties / Applications: Mondur MR 5 has a relatively high reactivity together with an extended gel time due to the high monomer content making it especially useful for microcellular and solid specialty elastomers. Mondur MR 5 also has utility in adhesive and sealants applications. As with any product, use of Mondur MR 5 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
