Polyurethanes

Polyurethanes

 

Polyurethane is a plastic obtained by the reaction of polyol and isocyanate in the presence of catalysts and additives. Polyurethanes are best known for foams, but they are much more than polyurethane foams, as they are one of the most versatile polymers in existence.

Polyurethane systems consist of two liquid components, one of which is a mixture of polyol with other additives and a diisocyanate, which, when mixed homogeneously, reacts to form the polyurethane.
Depending on the polyol and isocyanate used, a variety of products are classified according to physical structure, conventional flexible, rigid, elastomers, coatings and adhesives. These are the families or product segments that are also used for control in the polyurethane industry. It is also a classification for elastomers, coatings and adhesives known as CASE, Coating Adhesives Sealants Elastomers.

Liquid Masterbatches

The liquid colors are usually used in polyurethanes because they allow excellent dispersion and color distribution by the polymer matrix. Adplast® offers the rubber industry an unmatched color service for their specific color requirements and applications.
