Polyurethanes are the most important modern synthetic materials used virtually in every area of life. Their application in many sectors of industry will be increasing constantly as they are one of the most technologically advanced materials. Polyurethanes are characterised by different degree of rigidity, flexibility and resistance. These features can be precisely designed at the production stage. Polyurethanes, thanks to their diversity, are used in thermal and acoustic insulations of housing, office and industrial buildings. They are also widely used in automotive, furniture and mining industries and in the production of elements for playgrounds, sport surfaces and many other.
All construction materials, including natural ones, emit a determined quantity of chemical substances to the air in closed spaces. This affects the quality of the air and therefore influences health, comfort and safety of people breathing it. One of the ways to assess the safety of used materials is the Emission Classification of Construction Materials which was developed by the Finnish Building Information Foundation (RTS). Detailed tests for the emission of formaldehydes, volatile organic compounds, ammonia and carcinogenic substances allow to assign a determined class to a given material: M1, M2 or M3. The first one is characterised by the lowest chemicals emission level and thus is being awarded to the highest quality and safety level products. The quality verification of building materials by the RTS is not mandatory, yet a lot of manufacturers and distributors use this system to support the development of the construction market towards the low-emission components.
The wide PCC Group offer includes several solutions based on polyurethane for the production of rigid, semi-rigid, elastic and integral polyurethane foams, as well as glues and adhesives. They comprise one- and two-component polyurethane systems among which the following product groups can be distinguished: EKOPRODUR, EKOPROMER, EKOPROFLEX, PROMOFLEX and PROMOPUR.
The high quality of spray polyurethane systems (PUR) with closed cell structure, i.e. EKOPRODUR S0329, EKOPRODUR S0329W and EKOPRODUR S0540 systems, is confirmed by the Finnish research institute – Building Information Foundation (RTS). A series of comprehensive tests were performed and the results confirmed low emission level of offered solutions and made it possible to obtain the highest rating – M1 class. The awarding of the Certificate to PCC Prodex is a clear evidence of the company’s efforts effectiveness to introduce the environment-friendly products to the market and to care about health and safety of the users.
The above-mentioned products passed strict tests for the emission of volatile organic compounds (VOCs) in construction materials and complied with the requirements of the classification of air quality inside buildings. Volatile organic compound is virtually any organic substance which spontaneously evaporates in normal ambient conditions (of pressure and temperature). According to the EU 2004/42/EC directive, the term VOC covers all the volatile organic compounds with the boiling temperature between 50°C and 250°C measured at the normal pressure of 101,3 kPa.
