PIR

Pirocel

Semi-rigid polyurethane foam provides the best insulation capabilities of 0.016 to 0.024 kcal/mh? out of any organic or inorganic insulation materials.

The categories of semi-rigid polyurethane foam are mainly divided into PUR(POLY URETHANE) foam and PIR(POLY ISOCYANURATE). nPIR is the upgraded product of PUR by improving on the weaknesses in inflammability, deformability and dimension stability.

Eco-friendliness

The product is a form of polyurethane expanded through chemical reactions and is an eco-friendly material that produces little gases harmful to the human body.

Heat insulation

The product undergoes little change in thermal insulation capability with a lapse of time; its thermal conductivity ranges 0.015~0.017kcal/mhoC, which is by far better in insulation than other materials. The high insulation capability enables construction of structures with less use of construction materials, thus achieving better space availability.

Physical properties

A wide range of applications are possible with good mechanical strength and moisture resistance as well as with good dimensional stability at low and high temperatures, chemical resistance, and thermal insulation.

Resistance to bending stress

A newly-developed production technique has successfully improved bending strength, which has been a major cause that imposes limitation to the use of urethane boards despite their excellent properties.

Constructability

The product also features easy cutting, little dust generation, and easy gluing, transportation, and workability.

Economic benefits

Use of a thin thickness of the material thanks to its excellent insulation capability enables the user to have larger floor areas and earn more money from selling space.
