Title:
THERMOPLASTIC ELASTOMER COMPOSITION, MOLDED ARTICLE, METHOD OF MANUFACTURING FOAMED MOLDED ARTICLE, AND FOAMED MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP2023058011
Kind Code:
A
Abstract:
To provide a thermoplastic elastomer composition capable of obtaining a molded article excellent in flexibility, high temperature rigidity, lightness in weight and vibration-damping property.SOLUTION: There is provided a thermoplastic elastomer composition obtained by formulating a polyamide resin (A) having a melting point of 200°C or higher by differential scanning calorimetry (DSC); a copolymer (B) containing a polymer block mainly composed of an aromatic vinyl-based compound having a reactive functional group, and a polymer block and/or hydrogenated products thereof mainly composed of a conjugated diene-based compound; and a copolymer (C) containing a polymer block mainly composed of an aromatic vinyl compound other than the component (B), and a polymer block and/or hydrogenated products thereof mainly composed of a conjugated diene compound. The composition ratio (weight ratio) of the polyamide resin (A), the copolymer (B), and the copolymer (C) is (A):(B)=50:50 to 75:25, (B):(C)=90:10 to 25:75, and (A):((B)+(C))=40:60 to 60:40. In a morphology observed by using a transmission electron microscope, the average particle diameter of a black or white dispersed phase is 1.0 μm or less.SELECTED DRAWING: None
