“Polyols” is a generic term for multivalent alcohols, organic compounds that contain at least two hydroxyl groups in the molecule. PCC Rokita SA focuses particularly on the manufacture of polyether polyols. These polyols react, for example, with isocyanates to produce polyurethane (PU).
Polyurethane has a large number of applications, and it is the polyols employed that determine its properties. Under the brand name Rokopol®, PCC Rokita SA offers more than 30 different polyols and polyol formulations. In addition, our Warsaw affiliate PCC Prodex Sp. z o.o. and its subsidiary PCC Prodex GmbH in Essen also develop, manufacture and market PU systems.
Our polyether polyols are used, for example, to produce flexible PU foams which provide the basis for comfortable cold-cure foam mattresses and upholstery of high rebound elasticity. Automotive seats and bicycle saddles are likewise manufactured from PU foams, as is the moulding foam used for car dashboards. PU is a component of the flooring products used in sports halls and also the soles of high-comfort sports shoes. Products based on our polyether polyols ensure the thermal insulation properties in refrigeration vehicles. And assembly foams are likewise manufactured from polyols. Our specialty polyols can be found in coatings, adhesives, waterproofing compounds and sealants. PU elastomers, i.e. rubber-like substances, are developed from specialty polyols for the manufacture of, for example, textile fibres. This group of applications falls under the CASE heading (coatings, adhesives, sealants, elastomers). And even imitation leather is manufactured from polyurethane based on polyols.
The applications of our PU systems are likewise widely varied. They extend from thermal insulation products, as used in pipelines for example, to specialty PU adhesives applied in mining to consolidate crumbling rock strata and provide a reliable seal against inflowing water. We have also developed a PU foam spray system for roof insulation applications in the construction industry. This enables rigid foam to be sprayed in liquid form as a roof coating to enhance the thermal insulation of buildings. The reaction mixture begins to foam within a few seconds, producing a seamless and jointless layer that offers outstanding insulation values.
