Polyurethane is a polymer obtained through the reaction of a  di-isocyanate  with a blend of poly-alcools (polyols).This polyols blend may include also catalysts, blowing agents, flame retardants, surfactants and other additives so to obtain the most desirable reaction profile and a polymer with the specific and defined wished properties.

The polyurethane chemistry allows to obtain, according the used formulation, either thermosetting or thermoplastic products. Polyurethanes are extremely versatile polymer both for the physical and mechanical properties (rigid, semi-rigid, flexible, foamed etc….) and for the application technologies (pouring, spraying, injecting, etc …..). Polyurethanes can be then produced in various forms or shapes: elastomers, rigid foams, with closed or open cells, flexible or visco-elastic foams, fibers, adhesives, sealants, high density and structural foams, self skinning semi-rigid foams etc…..

All the above mentioned possibilities are achievable thanks to the availabilitity of a wide range of raw materials ( isocyanates, polyols, etc...) which allows to obtain a practically unlimited number of different formulations ( the polyurethanes systems) so to get products suitable for such a large variety of applications.

Since the 30s  when they have been “invented”  the industrial development of the different polyurethane typology as allowed the production of articles which are now part  of our daily life: thermo and sound insulation, paints, furniture, shoes, fabric leathers, adhesive and sealants, car seats and padded items (crash pads etc…), medical items (hearth valves, blood bag etc…), spandex, …….

In the last decades the polyurethane chemistry has continuously made impressive progress both in the final products and their apploication as well as in the raw materials where, for example, several polyols have been developed starting from renewable sources (vegetable origin) which are opening new exciting prospects.

At present  PolySysTem is mainly working in some specific application segment (see the “Product” section) where the polyurethanes are excelling for the variety of their properties, as:

In the thermo insulation polyurethanes are, to day, the most efficient and versatile available product so, whenever an high performance is demanded, it is more and more the standard product for this application.

Last but not least it is now a quite well accepted fact that energy has to be saved to protect our  environment. Therefore this lets foresee a continuously increase in the use of  the polyurethane insulation which can then offer to the Humanity a key contribution to its development.
