RIGID POLYURETHANE FOAM. THERMAL INSULATION MATERIAL USED IN CONSTRUCTION

LAS ESPUNAS DE POLIURETANO RIGIDO COMO MATERIAL PARA AISLAMIENTO TERMICO EN LA CONSTRUCCION

Rigid polyurethane foam is an excellent thermal and sound insulation material for use in construction, which weighs very little. This foam contains two liquid ingredients: resin and prepolymer. The three methods of manufacture are described: direct proportioning by hand, continuous-or intermittent-production machines, or spraying machine. Details are given of the physical and chemical characteristics of the product together with standards for the selection of the machine best suited to each particular case. The foam can be used for finishing concrete surfaces and metal parts in chemical plants for example. It can also be utilized in the repair of pavements damaged by deicing salts. A very thin layer of polyurethane foam affords very good insulation and high strength. /TRRL/
