LOW-RESILIENCE FLEXIBLE POLYURETHANE FOAM AND PROCESS FOR PRODUCING THE SAME

摘要

A flexible polyurethane foam whereby exceedingly low resilience can be obtained without using a plasticizer and the hardness change due to a temperature change is little; and a process for its production, are provided. The flexible polyurethane foam is characterized by having a core resilience of 30% or lower and a glass transition point within a range of from -80 DEG C to -60 DEG C. The process for producing a flexible polyurethane foam comprises reacting a polyol with a polyisocyanate compound in the presence of a catalyst, a foam stabilizer, and a blowing agent, and is characterized by using as the polyol a polyol(1) having a hydroxyl value of from 5 to 15 mgKOH/g.
