Abstract

차수(遮水)테이프의 강성(剛性)의 적정화에 의하여 케이블에의 감기작업성을 개선하고, 또 케이블외관상도 주름이 없는 양호한 것이 얻어지도록 한다.By optimizing the rigidity of the order tape, it is possible to improve the winding workability to the cable and to obtain a good appearance without wrinkles in the appearance of the cable.

시트기재(基材)상에 단위중량이 40g/㎡이하의 흡수성 조성물층이 배설된 2층구조의 것, 또는 1쌍의 시트기재의 사이에 단위중량이 40g/㎡이항의 흡수성 조성물층이 개재된 샌드위치구조의 것으로서, 그 종방향의 강성치가 0.2~1.5gf/㎝의 범위에 있고, 또한 횡방향의 강성치가 0.2~0.6gf/㎝의 범위에 있다.A two-layer structure in which a water absorbent composition layer having a unit weight of 40 g / m 2 or less is disposed on a sheet substrate, or an absorbent composition layer having a unit weight of 40 g / m 2 or more between a pair of sheet substrates. In the sandwich structure, the longitudinal rigidity is in the range of 0.2 to 1.5 gf / cm, and the stiffness in the lateral direction is in the range of 0.2 to 0.6 gf / cm.
