To address future market needs, Arkema, a major player in blowing agents for polyurethane and polyisocyanurate insulating foams in construction, is in the process of developing HFO (hydrofluorolefins), the fourth generation blowing agents to replace HFCs, the current generation fluid. According to Arkema, the next generation will enjoy a better environmental performance while maintaining the general properties including insulation properties for rigid polyurethane foams.
