Isocyanates
Isocyanates are essential raw materials used in the production of polyurethane systems. Depending on their chemical structure and reactivity, MDI- and TDI-based isocyanates are used in a wide range of polyurethane applications, from flexible and rigid foams to CASE applications.
The KIMraw® product group includes a range of isocyanate products designed to meet different application requirements.
Polimerik MDI (PMDI)
PPolymeric MDI (PMDI) is a widely used isocyanate for the production of polyurethane systems. It is commonly preferred in sandwich panels, spray polyurethane foam, refrigerator insulation, and pipe insulation, as well as other rigid foam applications. The KIMraw® product group offers both PMDI and High Functional (HF) PMDI product options.
Monomerik MDI
Monomeric MDI refers to the high-purity monomeric form of methylene diphenyl diisocyanate (MDI). MDI 50 and MMDI are monomeric MDI grades with different isomer compositions and purity levels. MDI 50 consists of a blend of 4,4′-MDI and 2,4′-MDI isomers, while MMDI consists of high-purity 4,4′-MDI. The KIMraw® product group includes both MDI 50 and MMDI to meet different application requirements.
Modified MDI
Modified MDI is an MDI grade produced through carbodiimide modification. With its modified chemical structure compared to standard MDI, it is used in polyurethane systems developed for different application requirements. The KIMraw® product group offers Modified MDI products.
TDI 80/20
TDI 80/20 is a grade of toluene diisocyanate (TDI) consisting of 80% 2,4-TDI and 20% 2,6-TDI isomers. Widely used in the production of polyurethane systems, this isomer blend is one of the standard TDI grades.
