Polymer composition for power molding, power thereof, foamed object, and process for producing foamed object |
摘要 |
A polymer composition for powder molding, containing (A) to (E) described below: (A) a peroxide-crosslinkable olefin-based copolymer having a melt flow rate measured under the conditions of a load of 2.16 kgf and a temperature of 190° C. according to JIS K7210 of 1 g/10 min. or more; (B) 0.1 to 10 parts by weight of a peroxide having a temperature for obtaining a half life of 10 hours of 100° C. or more, per 100 parts by weight of (A); (C) 0.1 to 7 parts by weight of a crosslinking aid per 100 parts by weight of (A); (D) 0.1 to 20 parts by weight of a thermal decomposition type foaming agent per 100 parts by weight of (A); and (E) 0.1 to 10 parts by weight of a foaming aid per 100 parts by weight of (A), a powder and foamed article of the polymer composition, a method for producing the foamed article, and a molded article containing the foamed article, and further the polymer composition is excellent in the storage stability of its uncrosslinked composition, and can provide a foamed article having a high expansion ratio and an excellent surface skin, and hardly having a skin lack of hiding.
