Title:
POLYOLEFIN-BASED ELASTOMER COMPOSITION AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2015086246
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyolefin-based elastomer composition good in surface appearance, and capable of achieving a molded body having no odor, stickiness nor oozing.SOLUTION: There is provided a polyolefin-based elastomer composition can be obtained at least by melting and mixing (A) olefin-based elastomer of 100 pts.mass, (B) a polypropylene resin of 70 to 210 pts.mass, (C) hydrocarbon oil having an average molecular weight of 400 to 1000 and the content of a component having molecular weight of 400 or less of 30 mass% of 3 to 300 pts.mass. There is also provided a polyolefin-based elastomer composition having a polymer aggregate of 1 to 150 with 0.3 to 0.5 mm and 1 to 150 with 0.5 to 1.0 mm when the polyolefin-based elastomer composition is compression molded to a film having 0.1 mm thickness, light is radiated to one side surface of the film and a 5 cm×5 cm region of another side surface.
