Water as the only foaming agent for the insulating component
In an era in which quality is synonymous of progress, P3 has always tried to improve its products to conform them to the growing requirements of the market. Piral HD Hydrotec panel is the fruit of this effort; it is in fact produced by P3 using, the International patent EP 1115771 B1, for which P3 has obtained exclusive rights, that allows the countersigning of Hydrotec panel with the mark ODP=0 (ozone depletion potential = 0), as to say not harmful for the ozone. Environmental compatibility is ensured by the use of water as the foaming agent instead of cfc and hcfc or the hydrocarbons usually used in insulation foams, responsible for the destruction of the ozone layer of the atmosphere.

Hydrotec panel conformity to European standards
P3 preceded the application of European Standards regulating the use of CFC and HCFC gas that were banished in the production of stiff polyurethane (PUR) as of January 1st, 2003.
The water-based foaming process eliminates completely both ODP and VOC (the release of volatile organic substances into the atmosphere during the production of the panel and its working life) as well as the “greenhouse effect” or GWP (global warning potential).

Hydrotec, innovative technology!
When reaching the atmosphere, chlorinated gases like CFC and HCFC are struck by ultraviolet radiation that leads to the release of radical chlorine through photodissociation. The radical chlorine then reacts with the ozone and causes its destruction. Traditional polyurethane foaming technology exploits the heat of the exothermic reaction between polyol and isocyanate to evaporate a liquid with a low boiling point previously added to the mixture. Most of these gases remain trapped inside the cellular structure of the polyurethane polymer being formed. With the passage of time, the composition of the gas contained in the cells may vary due to the natural tendency to reach equilibrium with the outdoor surroundings. This process is significantly influenced by the type of external facing given to the foam and its density, operating temperature, formulation, and the type of gas, etc. In the new P3 technology, foaming is obtained only by the gas generated through the reaction between isocyanate and water during the polyol/isocyanate reaction process with the consequent formation of the polyurethane chain just the same.
