Isocyanates and Polyols
Isocyanates
Lupranat® isocyanates from BASF are utilized across a large range of applications and industries. Products include monomeric and polymeric methylene diphenyl isocyanate (MDI), toluene diisocyanate (TDI), modified MDI, and MDI prepolymers.
Toluene Diisocyanate (TDI)
BASF’s Lupranat® T 80 is a mixture of 80% 2,4-isomer and 20% 2,6-isomer of Toluene Diisocyanate (TDI). Lupranat® T 80 is used for the production of slabstock and molded foam as well as for various CASE applications.

Monomeric MDI
Monomeric MDI (mMDI) refers to 4,4’- and 2,4’-isomers of Methylen Diphenyldiisocyanate. BASF offers two standard monomeric MDI grades: pure 4,4’-MDI and a blend of 4,4’-MDI and 2,4’-MDI. Besides the standard mMDIs, various mMDI types with different stabilization and reactivity are available. Although pure 4,4’-MDI is a crystalline solid at room temperature, it is commercially available as a liquid but with a limited shelf life. Monomeric MDIs are either used as pure isocyanate, in mixtures with polymeric MDI (pMDI) or in prepolymers for flexible foams, CASE applications, shoe soles or thermoplastic polyurethanes.

Carbodiimide Modified MDI
Given the handling and storage difficulties associated with pure 4,4' MDI, carbodiimide chemistry is often used to modify and stabilize monomeric Methylene Diphenyldiisocanate (mMDI). Carbidiimide modified isocyanates are liquids that are stable and clear at room temperature. These products contain a portion of mMDI that is reacted to give a tri-functional uretonimine species within the remaining difunctional mMDI.

Polymeric MDI
Polymeric Methylene Diphenyldiisocyanate (pMDI) is a brown mixture of monomeric (2-ring) and polyaromatic 3-ring and higher species) Methylene Diphenyldiisocyanates, which is liquid at room temperature. A higher pMDI viscosity indicates a lower content of monomeric and a higher content of polyaromatic components; that is, as pMDI viscosity increases, so does isocyanate functionality. BASF offers a range of pMDIs with different functionality and reactivity. PMDI is mainly used for the production of rigid foam, pMDI grades are also used as a binder in the wood-working industry. In combination with mMDI grades, polymeric MDI is also used to produce various types of flexible foam and CASE applications.

MDI Prepolymers and Mixtures
In addition to the standard polymeric MDI (pMDI) and monomeric MDI (mMDI) grades, BASF offers isocyanate prepolymers and isocyanate mixtures optimized for certain applications. Prepolymers are modified isocyanates accessible by a reaction of isocyanates or isocyanate mixtures with polyether polyols. BASF’s isocyanate mixtures and prepolymers have been designed to provide excellent processing performance combined with outstanding mechanical properties of the final product.
