MDI
MDI is a material that belongs to the ISOCYANATE family and, after being mixed with PPG, is used to produce polyurethane which is used in everyday life.
Polymeric MDI (CRUD MDI )
M11S, M20S, and M50 : These MDI products are widely used across a diversity of sectors, including the polyurethane foam sector for refrigerators, refrigerated containers, building insulation panels, spray heat-preservation and insulation materials, pipe insulations, synthetic wood etc. and the semi-hard polyurethane foam sector for car interiors such as in-panels, armrests, sun visors, etc., as well as for adhesives, coatings, and waterproof flooring.
Monomeric MDI (PURE MDI )
MS (solid) and MI: These MDI products are widely used as raw materials to produce a diverse range of industrial products, household goods, and sports goods, including spandex (elastic fibers), shoe soles, TPU elastomers, synthetic leather, coatings, and adhesives.
Modified M D I
MM103C, MP102, and MP105 : These MDI products are widely used for car interiors such as steering wheels and air bag covers, for making prepolymers used in waterproof flooring, and for making shoe outsoles (sports products) and adhesives.

Extenders
ASP-170: This material has a small particle size and has excellent gloss, so it is mainly used for making coatings, inks, and paints.
ASP-200 and ASP-G90: These materials have normal gloss and are mainly used for priming ships and cars, as well as for coils and for industrial purposes.
SAT-W: This material has a small particle size and bright gloss, so it is used for interior and exterior coatings for buildings and structures.
SAT-5HB: This material has a very small particle size and a high level of gloss, so it is used for TIO2 extenders and synthetic rubber.
ATTAGEL-50: Because of its fine particles, this material is used for the undercoating and final coating of aqueous coating and for coating plastisols and asphalt.
