Fine chemicals is a chemicals industry that requires advanced technology, unlike large-scale chemicals industries such as the petrochemical industry, chemical fertilizer industry, and cement industry. We supply urethane raw materials, coatings, and
coating materials as well as fine chemical products including inorganic chemicals such as nitric acid and ammonium nitrate to all corners of the world.
A benzene based aromatic diisocyanate, MDI is divided into three product categories
Polymeric MDI: Used in various applications including rigid foam, semi-rigid foam, and cases. Divided into different grades by viscosity to suit various purposes.
Monomeric MDI: Pure MDI created through high-purity refining. Used for spandex, TPU, synthetic leather, and various elastomers.
Modified MDI: Modified MDI is created by carbodiimidizing monomeric MDI, so it can maintain a low-viscosity liquid state at room temperature. It is easy to handle and improves foaming properties and formability when used in polyurethane foam.
Polymeric MDI : Refrigerators, construction panels, and spray foam
Monomeric MDI : Spandex, TPU, synthetic leather, and shoe soles
Modified MDI : Steering wheels, adhesives, and tracks
Toluene Diisocyanate (TDI) and Polypropylene Glycol (PPG)
TDI is a toluene based aromatic diisocyanate, and PPG is an ether polyol.
The urethane reaction of the two chemicals creates soft urethane foam, which is used in various applications such as furniture and bed interiors.
