PUR Introduction :
In terms of raw material proportioning and process output, our PUR products employ the globally advanced six-component online automatic operation mixing and pouring technology and have realized six-component continuous foaming for the first time in China.With the technology,mixing and proportioning process may be finished in an online way ; the formula may be adjusted according to environmental changes;air feeding and mixing devices may be used to make raw material mixing more even and foam finer,thus producing high-strength ,energy-saving and environment friendly building boards
PIR Introduction :
POILISOCYANURATE is called PIR for short. For the composite boards developed,excessive isocyanurate is added and ring structure and higher isocyanurate index are employed in the compounds to form compact PIR products, thus ensuring greater stability and excellent heat and fire resistance for the internal rigid foams . Experiments show that the products may endure a temperature up to 200ºC in short time or to 160ºC for long time .
The rigid polyurethane foam core provides excellent thermal insulation for buildings.This comes from the excellent thermal conductivity coefficient, λ = 0.022, unparalleled by any mineral wool or EPS sandwich panel. The concealed fasteners mean just that: the joints between the panels are hidden from sight, which improves the aesthetic value of the result.
Besides the superb solidity and durability with a beautiful appearance, the hard polyurethane resin foam used for panels performs quite well in heat insulation.
