弱く、層割れし易く、発泡倍率も低く、重く、高価であ
ると言った欠点があった。Conventionally, foam adhesive tapes have mainly used neoprene rubber or EPT rubber sponge as the foam base material. When manufacturing these foams, it is not possible to make them thin, so thick foam is sliced and used, and because the cells of the air bubbles on the surface are cut, the adhesive penetrates into the air bubbles, resulting in a large amount of foam. There were drawbacks that made it necessary. Further, there were disadvantages such as the strength of the base material was low, the layers were likely to crack, the expansion ratio was low, and the base material was heavy and expensive.
