The object of the present invention is to provide a masking member which has good heat resistance and can be used repeatedly. To attain this object, the present invention provide a masking member made of a polymer alloy including one or more kinds of engineering plastics selected from a group consisting of methylpentene copolymer, polysulphone, polyethersulphone, polyphenylene, sulphide, polyphenylene ether, polyamideimide, polyetherimide, polyether-etherketone; and polyamide and/or polystyrene, and styrenic thermoplastic elastomer wherein said engineering plastics and said polyamide and/or polystyrene are mixed together in a weight ratio between 30:70 to 70:30, and 2 to 20 parts by weight of said styrenic thermoplastic elastomer is added in 100 parts by weight of said engineering plastics and polyamide and/or polystyrene. Said masking member has excellent moldability, a high level of mechanical strength and a good affinity with the coating film.
A reusable masking member protect a prescribed part of an article from a coating applied to said article, said masking member being a polymer alloy manufactured by molding a sheet comprising one or more kinds of engineering plastics (1), polyamide and/or polystyrene (2), and styrenic thermoplastic elastomer (3), wherein said engineering plastics (1) are selected from the group consisting of methylpentene copolymer, polysulphone, polyethersulphone, polyphenylene sulphide, polyphenylene ether, polyamideimide, polyetherimide, and polyether-etherketone;
