Polyurethanes

In the plastics market, polyurethanes (PUR) lead the way as the materials that make "life easier, safer and more convenient".

They are mainly in the form of polyurethane foams obtained through the reaction of multifunctional isocyanates with polyols, including polyether polyols and many excipients. Because of this diversity, the possibilities of their synthesis are virtually endless.

Application of polyurethanes

Due to the wide array of their properties, polyurethanes have become known as a unique group of polymers, which are used in such areas of life and economy, as transport, construction, furniture industry and mining. Today, few can realize that polyurethanes are widely used in everyday life, among others, in homes, cars, sports equipment or even clothing. In addition to polyurethane coatings, moulded upholstery profiles, rigid bumper foams and interior components, such as dashboards or headlining, are used in the automotive industry. Polyurethanes are present in seats in airports, airplanes, trains, buses or bicycles. In addition, products, such as different coloured bath or dishwashing sponges, window and door sealing foams, are also made of polyurethane. In construction, polyurethane blocks, sandwich panels, one-component foams or spray insulation are widespread. Polyurethane adhesives that are used in mining, quarrying industry and tunnel construction are more and more widely used. Elastic polyurethane foam is used in the furniture industry as upholstery foam and in the production of mattresses, viscoelastic pillows (viscoelastic foam, memory foam) and in the shoe industry and textile. Healthcare also benefits from polyurethane-based solutions (e.g. artificial organs). Components of operating tables and wheelchairs are made of antistatic polyurethane integral foams.

The advantages of polyurethanes

Polyurethane products are characterized, among others, by good elasticity (even at high hardness); unique abrasion resistance and tear strength, as well as resistance to grease, oil or ultraviolet (UV) radiation. An additional advantage of polyurethane materials is their relatively easy industrial processing, while maintaining high productivity. At the same time, finished PUR products do not get destroyed in heavy use. Thus they are increasingly used as a substitute of rubber, wood, metal or ceramics. This is advantageous in significant reduction of the total weight of the finished products.

Main products

To meet customer expectations, the PCC Group offers a range of specialized products for the manufacture of polyurethane systems. The rich portfolio includes polyether polyols (diols, triols), sugar polyols, Mannich polyols, sorbitol polyols, polymer polyols, as well as numerous additives, such as crosslinkers, emulsifiers, and flame retardants. The latter effectively reduce the flammability of polyurethane foams and make it possible to get the optimal balance between a flammability reduction and mechanical properties. An important part of the PCC product range are finished one- and two-component polyurethane systems for the manufacture of the aforementioned types of foams, adhesives or sealants. Also, systems designed for the production of semi-rigid and rigid polyurethane foams are an important part of our product range. They are widely used as thermal insulation, acoustic insulation (PUR, PIR insulation), systems used in areas related to the CASE (coatings, adhesives, sealants and elastomers) applications and systems for the production of moulded elastic and integral moulded polyurethane profiles.
