PURIOS spray foam systems
PURIOS polyurethane systems are high-quality materials for thermal insulation in buildings. Applied on-site as two components using a high-pressure spray machine, they create durable and efficient insulation. This method achieves excellent thermal insulation properties and meets all construction requirements.
Components of the Purios system
The formation of foam is a complex process involving chemical reactions and physical phenomena. The mixing of components A and B initiates the polymerization reaction. As a result, short chains of polyols and isocyanates bond together to form significantly longer polyurethane molecules. Due to the exothermic nature of this reaction, the temperature of the physical blowing agents present in the mixture rises. The so-called “blowing agents” and carbon dioxide (a byproduct of the polymerization reaction) cause the formation of foam.
The resulting foam has a volume more than 100 times greater than the sprayed liquid components of the system. Furthermore, the ongoing polymerization reaction causes the final product to harden and cool.
How Purios spray foams are formed
Purios insulation systems consist of two types of PUR foam: closed-cell and open-cell. The differences between them arise from the predominant nature of the cells that make up the final product. Closed-cell foam is composed of over 90% closed-wall cells.
Open-cell foam is a diffusively open material (over 90% of its cells have open walls). The pores formed due to the expansion of carbon dioxide are quickly filled with air. Its thermal insulation is lower than that of closed-cell foam; however, this alternative material offers other benefits, including low density. This means high production efficiency, no load on building partitions, and diffusively open walls that create “breathable” structures.
Production of Purios systems on demand
As one of the largest manufacturers of PUR foam, we offer several spray systems that vary in their properties. Depending on our customers’ expectations, we can prepare a system with specific parameters for the finished foam. For nearly 20 years, numerous business partners in many countries across Europe have been using our systems.
Applications of closed-cell and open-cell Purios foams
Both types of foam have gained recognition as a modern construction thermal insulation material with excellent properties. The spray application method allows for precise filling of every space, gap, and crevice, helping to avoid thermal bridges. Thus, polyurethane foam is particularly recommended in an era of increasing expectations for thermal insulation due to tightening building regulations.
