Methylene Diphenyl Diisocyanate (MDI) CAS:101-68-8 Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock. There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MDI contains monomeric MDI and products with higher […]

Neo Pentyl Glycol (NPG)
Neo Pentyl Glycol Chemical Structure Composition
Neo pentyl glycol (NPG) is produced with formaldehyde and isobutyraldehyde in an aldol reaction. The intermediate obtained is converted to NPG with catalytic hydrogenation of the aldehyde group to the neo pentyl glycol.
Neo pentyl glycol (NPG) is used in production of polyester resins for coatings, Gel coats (top coat of composite), coil coatings, synthetic lubricants, plasticizers, adhesives.
Improve the heat stability of polyester.
