Title:
URETHANE FOAM COMPOSITION AND BUMP CUSHION
Document Type and Number:
WIPO Patent Application WO/2015/033734
Kind Code:
A1
Abstract:
The problem to be solved by the present invention is to provide a urethane foam composition which can be molded into an article that has excellent repeated compression durability and scarcely loses elasticity thereof. The present invention provides: a urethane foam composition characterized by comprising a main ingredient (i) and a curing agent (ii), wherein the main ingredient (i) comprises a urethane prepolymer (A) having an isocyanate group, the urethane prepolymer (A) can be produced by reacting a polyol (a1) having a number average molecular weight of 800 to 3,000, a polyisocyanate (a2) and a glycol (a3) having a branched structure and a number average molecular weight of 80 to 300 with one another, and the curing agent (ii) comprises a compound (B) having an active hydrogen atom and water (C); and a bump cushion which is manufactured using the urethane foam composition. The urethane foam composition according to the present invention enables the production of a molded article that has a long usable time, excellent workability and excellent repeated compression durability and scarcely loses elasticity thereof.
