What is polyurethane?

Durable, flexible and high-performance modern polymer technology

Polyurethane; It is formed by reacting a polyol and an isocyanate under suitable conditions. It is a type of polymer with wide usage in modern industry. With advanced formulations It is possible to obtain different hardness, flexibility, adhesion and strength profiles.

polyurethane material, of a polyol with suitable catalyst and additives a diisocyanate It occurs as a result of polymerization by reacting with . The structure that emerges at the end of this reaction has thermoset properties; i.e. high heat, chemicals and Its mechanical strength is at a high level.

Component A — Polyol

Polyether or polyester-based polyols; Includes catalyst, silicone, colorant and is created by adding different additives. Free hydroxyl (OH) They carry groups.

Component B — Isocyanate

The most common isocyanates: TDI (Toluene Diisocyanate) And MDI (Methylene Diphenyldiisocyanate). Foam, elastomer and plastic It is used extensively in the production of products.

Polyurethane; flexible or rigid foams, elastomers, high-strength adhesives, gaskets, It is the basic construction material in many products such as carpet underlays and hard plastics. Flexible polyurethane foams As comfort material in beds and furniture While using, hard foams It is one of the most effective solutions in heat and sound insulation.

Polyurethane Raw Materials

Basic components used in polyurethane production

polyols

Polyether polyols obtained by the reaction of epoxides or obtained by polycondensation Polyester polyols play a fundamental role in the production of polyurethane. 2000–10000 molecular weight in flexible materials; Molecular weights of 300–700 are used in hard products.

Isocyanates

Aromatic diisocyanates such as TDI and MDI are used extensively. Foam production, elastomer They have wide usage areas in soles, industrial insulation products and plastic industry.
