Title:
POLYPROPYLENE INJECTION FOAM MOLDING
Document Type and Number:
Japanese Patent JP2019059854
Kind Code:
A
Abstract:
To provide an injection foam molding that has excellent impact resistance and shows an excellent foamy state at a high expansion ratio.SOLUTION: A composition contains a conjugated diene modified polypropylene resin (A) that is a conjugated diene modified propylene-ethylene block copolymer in which a melt flow rate at 230°C, 2.16 kg load is less than 1-100 g/10 min., and a polypropylene resin (B) that is a propylene-ethylene block copolymer in which a melt flow rate is less than 1-80 g/10 min., where, an ethylene component content in (A) component is 1 wt.% or more, and relative to 100 wt.% of the total of (A) component and (B) component, the content of (A) component is 1-49 wt.% and the content of (B) component is 99-51 wt.%. The composition is injection-molded at an expansion ratio of 2.5-8.0 to obtain an injection molding body.SELECTED DRAWING: None
