CONNECTABLE MASKING MATERIAL FOR HOLE PART

摘要

A connectable masking material for hole parts enabling the easy masking material operation to protect the hole parts against surface treatment when the surface treatment such as painting is performed. A plurality of tapered plug-shaped masking materials (1B) formed of polystyrene foam bodies with an expansion ratio of 10 to 30 are integrally connected to each other in a same direction by using polystyrene foam beads. Thus, the connectable masking material (1B) for masking the plurality of hole parts (4) in which a connection part (2B) forms a minimum diameter portion and foam beads of 0.1 to 4.0 in quantity and 0.2 to 1.5 mm in diameter per mm<2> are present at the end face of the minimum diameter connection part can be easily bent off from the connection part (2B) without being damaged.
