POLYOLEFIN CROSSLINKED FOAM MOLDED BODY, POLYOLEFIN CROSSLINKING FOAM MOLDED BODY AND MANUFACTURING METHOD THEREOF, AND POLYOLEFIN CROSSLINKED FOAM PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin crosslinked foam molded body excellent in heat resistance and, if needed, mechanical strength and flame retardancy and excellent in appearance even with highly filling metal hydrate and a manufacturing method capable of manufacturing the molded body by an inexpensive extrusion foaming method, a polyolefin crosslinking foam molded body capable of manufacturing the polyolefin crosslinked foam molded body and a manufacturing method therefor and a polyolefin crosslinked foam product.SOLUTION: There are provided a manufacturing method having a process (i) of melting and mixing a polyolefin resin, organic peroxide, metal hydrate and a silane coupling agent at specific mass ratio to prepare a molten mixture and a process (ii) of foam molding the molten mixture while melting with using an extruder in a presence of a foaming agent, a polyolefin crosslinked foam composition manufactured by the same and a polyolefin crosslinking foam molded body and a polyolefin crosslinked foam product.SELECTED DRAWING: None
