Product Description

Superior fire properties
PIR (Polyisocyanurate) foam offers the possibility to meet existing and future panel regulations. It has all the positive attributes expected of a PUR foam: it is lightweight and offers good thermal conductivity and moisture resistance, making it superior to mineral wool (MW) or expanded polystyrene (EPS)-based panels. Importantly however, it can also be used to address panel applications where fire resistance is essential. Employing environmentally friendly, halogen-free ingredients to achieve good fire properties, PIR formulations are a reliable solution for panel projects where PUR foam is deemed unsuitable.
Standard production set-up
PIR technology was developed to work without an adhesive coating between foam and steel facings, thereby reducing processing complexities and production costs. When recommended process conditions are met, the adhesion between foam and steel facers as well as the surface quality of the panels, are both excellent. However, there are scenarios where the use of an adhesive coating may be beneficial, for example where there are variations in steel quality, difficulties in reaching minimum process conditions, or a requirement for high mechanical properties for particular end applications. If this is necessary, we can draw on its extensive understanding of adhesive chemistry to recommend a suitable bonding solution.
Easy foam processing
PIR foam is the outcome of a long-term research program that investigated the fire, flow and adhesion characteristics of PIR. The result is a product with a reaction profile optimized to allow easy foam processing and high production speeds. PIR technology also offers panel producers the flexibility to manufacture different panel types of varying thicknesses ranging from 50mm to 200 mm.
A range to suit customer needs
We offer a range of PIR systems with different NCO indices to meet individual customer laminating conditions and desired fire rating standards. As a rule of thumb, the higher the index, the better the fire properties of a foam and the higher the recommended minimum conveyor temperature. NB: the NCO index is always higher than 180, one of the parameters used to define PIR.
Reaction to fire
When it comes to reaction to fire, national tests are harmonized under EN14509. The mechanical properties of PIR sandwich panels have been determined according to this standard. The result is a panel system that meets customer expectations and is of a comparable quality to a standard PUR sandwich panel. The entire PIR product range also achieves a B1 fire rating. This result was achieved with a number of different joint designs and panel thicknesses.
