摘要：
The present invention relates to a semiconductive layer resin composition for a cable, which is excellent in strippability and stability under high temperature moisture-crosslinking conditions. The semiconductive layer resin composition of the present invention comprises a base resin consisting of 50 to 80 wt% of ethylene vinyl acetate copolymer and 20 to 50 wt% of high melting point polyolefin, said copolymer having been polymerized from a vinyl acetate monomer content of 30 to 70% by weight; and 20 to 80 parts by weight of carbon black based on 100 parts by weight of the base resin. More specifically, the high melting point polyolefin is at least one selected from the group consisting of ethylene-propylene copolymer, polypropylene and high density polyethylene, said ethylene-propylene copolymer having been polymerized from an ethylene monomer content of 5 to 20% by weight.
摘要（中）：
本发明涉及一种电缆用半导体层树脂组合物，其在高温水分交联条件下的剥离性和稳定性优异。 本发明的半导体层树脂组合物包含由50〜80重量％的乙烯 - 乙酸乙烯酯共聚物和20〜50重量％的高熔点聚烯烃组成的基础树脂，所述共聚物由乙酸乙烯酯单体含量为30 至70重量％; 和基于100重量份的基础树脂的20至80重量份的炭黑。 更具体地说，高熔点聚烯烃是选自乙烯 - 丙烯共聚物，聚丙烯和高密度聚乙烯中的至少一种，所述乙烯 - 丙烯共聚物由乙烯单体含量为5〜20重量％聚合而成。
