<p>PROBLEM TO BE SOLVED: To provide a composite resin particle that can produce a foam molding whose temperature dependence of the various physical properties such as falling ball impact value and mechanical properties (such as drop impact resistive compressibility and drop impact resistive property), is suppressed.SOLUTION: The problem is solved by a composite resin particle characterized in comprising a polyethylene-based resin and a styrenic resin and in which the polyethylene-based resin and styrenic resin are contained by a range of 50 to 20 mass% and 50 to 80 mass%, respectively, per total of said resins, the polyethylene-based resin is composed of a first polyethylene-based resin having a density from medium to high of 925 to 965 kg/mand a second polyethylene-based resin having a linear-chain shape and a density lower than the first polyethylene-based resin, the first polyethylene-based resin and second polyethylene-based resin are contained in a range of by 90 to 30 mass% and 10 to 70 mass%, respectively, per total of said resins.</p> |
