MDI Products
- Product
- BASF Lupranate® MI
- CAS number
- 101-68-8（4,4'-MDI）, 5873-54-1（2,4'-MDI）
Overview
Lupranate® MI is a pure MDI product, but contains a higher proportion of the 2,4' isomer than LUPRANATE® MS. The higher proportion of the 2,4'-isomer makes the MI product liquid at room temperature and relatively less reactive. From a chemical structure perspective, the 2,4' isomer is more flexible than the 4,4' isomer, and its functionality is 2.0.
Also known as
