| titleOfInvention | Polyisocyanate composition for hard polyurethane foam for cyclopentane foaming, and manufacturing method of rigid polyurethane foam using the same |
| abstract | The present invention relates to a polyisocyanate composition for hard polyurethane foam for cyclopentane foaming, and to a method for producing a rigid polyurethane foam using the same. (厚 物) It is a subject to provide the rigid polyurethane foam for heat insulating materials, and its manufacturing method. According to the present invention, an isocyanate group-containing prepolymer composed of a polymeric MDI (a1), a low molecular polyol (a2) having a side chain alkyl group and having 4 or more carbon atoms in the side chain and a molecular weight of 200 or less, and a foaming agent (a3). A polyisocyanate composition for hard polyurethane foam for foaming cyclopentane is used, characterized in that (A) is contained and the addition amount of the low molecular polyol (a2) is 3 to 10% by mass based on the isocyanate group-containing prepolymer (A). This problem is solved. |
