Title
(EN) CABLE SEALING COMPOSITION AND CABLE
(JA) 被覆電線シール用組成物及び被覆電線
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a cable sealing composition capable of obtaining a hardened material excellent in heat resistance, wet heat resistance, cold shock resistance and further flexibility, and to provide a cable coated with the composition.

SOLUTION: A cable sealing composition includes a 2-cyano acrylate compound. The 2-cyano acrylate compound is at least one alkyl-2-cyano acrylate selected from the group consisting of 2-cyano acrylate of 50 mass% or more but 99 mass% or less based on total 100 mass% and having an ether linkage to an ester residue, isopropyl-cyano acrylate of 1 mass% or more but less than 50 mass% and n-butyl-cyano acrylate.
