Abstract

[PROBLEMS] To provide polyisocyanates for use in producing a rigid polyurethane foam having an excellent balance between bondability and dimensional stability and a process for producing the rigid polyurethane foam. [MEANS FOR SOLVING PROBLEMS] The polyisocyanates for use in producing a rigid polyurethane foam comprise 85-99.7 parts by mass of a polymeric diphenylmethane diisocyanate and 0.3-15 parts by mass of either or both of at least one aliphatic isocyanate and at least one alicyclic isocyanate. Preferably, the polyisocyanates are used in combination with water as a blowing agent. The either or both of at least one aliphatic isocyanate and at least one alicyclic isocyanate preferably are either or both of hexamethylene diisocyanate and a modification thereof. The polyisocyanates preferably have a viscosity at 25°C of 200 mPa s or lower.
