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)

Toluene Diisocyanate (TDI)

In the chemical industry, TDI is used for the production of slabstock and molded foam as well as for various CASE applications.

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.

Lupranat® T 80

Blend of 80% 2,4- and 20% 2,6 toluene diisocyanate (TDI). Used mainly for the manufacturing  of polyurethane flexible foams for the mattress, furniture and automotive industries. It is also used for the production of polyurethane paints, adhesives and textile coatings.

Methylen Diphenyldiisocyanate (MDI)

Methylen Diphenyldiisocyanate (MDI)

Methylen Diphenyldiisocyanate is an essential raw material for polyurethanes, polyamidimid or foam, insulating foam and adhesives. It is one of the world’s most produced isocyanates besides TDI. In rare cases technical Diphenyl Methandiisocyanate is also used for the gluing for MDF-panels.

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.

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.

Lupranat® MM 103

Carbodiimide modified 4,4'-MDI. Used for the production of flexible polyurethanes such as microcellular elastomers, flexible and semi-rigid foams as well as for compact RIM parts. It is also used for the manufacturing of coatings and adhesives.

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.

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.
