Resin composition for foaming containing biodegradable resin, and foam manufactured therefrom

摘要

There are provided a resin composition for foaming including a biodegradable resin and a foamed article made thereof. The resin composition for foaming according to the present invention includes an ethylene-vinyl acetate resin, a biodegradable polyester resin containing a monomer of a double bond compound, a cross-linking agent, a co-crosslinking agent, a filler, and a foaming agent. In the resin composition, the double bond in the biodegradable polyester resin can be chemically cross-linked to the ethylene-vinyl acetate resin by a cross-linking agent, so that a compatibility with the ethylene-vinyl acetate resin can be improved, processability (mold releasability) during a mixing and melting process can be improved, and a foaming property and a mechanical property of a foamed article can be remarkably improved.
