Document Type and Number:
WIPO Patent Application WO/2015/119048
Kind Code:
A1
Abstract:
Provided is a master batch having excellent handleability during production, the master batch making it possible to mold a lighter weight expansion molded article, and the use thereof. A master batch containing heat-expandable microspheres configured from an outer shell comprising thermoplastic resin and a foaming agent that is vaporized by heating contained in the outer shell, and an organic base material component, wherein the melting point of the organic base material component is lower than the expansion start temperature of the heat-expandable microspheres, the melt flow rate (MFR, unit: g/10 min) of the organic base material component satisfies the equation 50 < MFR ≤ 2200, and the weight ratio of the heat-expandable microspheres is 30-80 wt% of the total weight of the heat-expandable microspheres and the organic base material component.
