polüuretaansegu

Polyurethane mixture, often referred to as polüuretaansegu in Estonian, is a versatile material formed by combining two main components: a polyol and an isocyanate. When these two react, they create a polymer known as polyurethane. The properties of the resulting polyurethane can be widely varied by adjusting the specific types of polyol and isocyanate used, as well as the addition of catalysts, blowing agents, and other additives.

These mixtures are commonly supplied as two-part systems that are mixed just before application. This mixing process initiates a chemical reaction that causes the material to expand, cure, and solidify. Depending on the formulation, polyurethane mixtures can be rigid or flexible, dense or foamy, and can range in hardness and elasticity.

The applications of polyurethane mixtures are extensive. They are widely used as insulating foams in construction for walls, roofs, and refrigerators due to their excellent thermal resistance. In the automotive industry, they are found in car seats, dashboards, and bumpers for their cushioning and impact absorption qualities. Other uses include coatings, adhesives, sealants, elastomers for footwear and sporting goods, and even in the production of synthetic leather. The ability to tailor the properties of the final polyurethane makes these mixtures a highly adaptable material for various industrial and consumer products.
