High functionality Methylene Diphenyl Diisocyanate (HFMDI) CAS:9016-87-9 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 […]

Glacial Acrylic Acid (GAA)
Glacial Acrylic Acid (GAA) is an unsaturated monocarboxylic acid monomer which is a clear, colourless liquid with an acrid odour which is miscible with water, alcohols and ethers. It’s molecular formula is C3H4O2
Glacial acrylic acid has useful properties such as flexibility, good weathering, adhesion, hardness and resistance to abrasion and oils and as such it is used as an additive in a wide range of products.
GAA readily copolymerizes with acrylic and methacrylic esters, ethylene, vinyl acetate, styrene, butadiene, acrylonitrile, maleic esters, vinyl chloride and vinylidene chloride.
Glacial acrylic acid Chemical Structure Composition.
Acrylic acid is synthesized by the oxidation of propene via acrolein.
GAA has 2 main application, for the polymeric application and for the manufacture of acrylate esters.
Glacial acrylic acid is commonly used as an additive in a variety of copolymer-based finishes, coatings, adhesives, inks, lubricants, textile, leather, paper finishes, floor polish, plastics, scale inhibitors, hair styling and finishing products, paints, lacquers, plastics, adhesives, dispersants, and thickeners.
It is also used in a range of esters for specialist applications such as in water treatment chemicals when it’s copolymerised with acrylamides, in drilling fluids, in mineral processing chemicals, detergent builders and in super absorbents polymers (SAP) for the production of nappies and sanitary products.
