Abstract
Provided is a thermoplastic resin composition for an interior material of automobiles, comprising a biomass-derived resin. The thermoplastic resin composition for an interior material of automobiles uses a biomass-derived resin, which replaces a petroleum-based thermoplastic resin, so as to reduce the generation of CO2, thereby providing an environmentally friendly effect.
Claims16
A thermoplastic resin composition for automotive interior materials, comprising:
- a biomass-derived resin and a non-biomass-derived resin for mixing,
- wherein the non-biomass-derived resin for mixing comprises a polyolefin in a form of an elastomer-phase rubber, polypropylene, and thermoplastic polyolefin (TPO),
- wherein the polyolefin in the form of an elastomer-phase rubber comprises a copolymer of ethylene and a C2 to C10 α-olefin, and
- wherein the TPO comprises a completely crosslinked TPO resin, a semi-crosslinked TPO resin and non-crosslinked TPO resins.
