By David Reed, UT EditorFoxhol, the Netherlands-Resina Chemie, the independent Dutch systems house, has introduced a rigid polyisocyanurate (PIR) foam system which, it claims, allows good processing on most modern production lines and overcomes the blistering problem encountered with earlier systems.Designated Foxopol PIR 3000, the system only requires moderate cooling, to about 18-22°C, with a double band temperature of only 45-55°C, Resina says. In addition, the system can be blown with pentane or HFCs (hydrofluorocarbons) in a thickness-range of 30 to 200 mm, and the resultant foams easily reach DIN 4102-B2 classification. Furthermore, Resina says, the PIR-foam panels achieve SBI-classification Bs2d0.Foxopol PIR 3000 is available in 200-litre drums, 1000-litre containers, and bulk tanks. It needs two separate catalysts to be produced, Resina says, adding that a technical datasheet (TDS) is available and that it can advise whether the system is suitable for processing on specific production lines: contact EMail: email@example.com”
