Document Type and Number:
Japanese Patent JP7448575
Kind Code:
B2
Abstract:
To provide a medical molded article that shows only a small change in hardness (Young's modulus) even with a change in the environment (such as temperature) before and after its insertion into the body and can retain high strength (sufficient tensile breaking stress and tensile breaking strain).SOLUTION: A medical molded article comprises a molded urethane resin having a polyol (A) and a polyisocyanate (B) as essential constituent monomer. The medical molded article is inserted into the body. The polyisocyanate (B) contains an alicyclic polyisocyanate (b1) of a specific structure and the polyol (A) contains a diol (a1) with a hydroxyl value of 30-300 mgKOH/g.SELECTED DRAWING: None
