    • 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.
    • 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。

    • A non-slip instrument is provided. The non-slip instrument includes an upper plate forming an appearance and including a plurality of insert holes punched therein, a non-slip unit inserted into the insert hole, a lower plate supporting a lower side of the non-slip unit at a position spaced from the upper plate, and a fixing unit connecting and fixing the upper plate and the lower plate to each other, the non-slip unit including a protruding portion exposed to the outside by being inserted into the insert hole, and a supporting portion formed integrally with the protruding portion and contacting with the undersurface of the upper plate. The non-slip instrument can prevent an inflow of foreign materials into the non-slip instrument and improve a supporting feeling.
    • 提供防滑仪器。 防滑装置包括形成外观的上板,并且包括多个插入孔中的插入孔,插入插入孔中的防滑单元,支撑防滑单元的下侧的下板,间隔开的位置 以及固定单元,其将上板和下板彼此连接固定,防滑单元包括通过插入插入孔而暴露于外部的突出部分和一体地形成的支撑部分 具有突出部分并与上板的下表面接触。 防滑仪器可防止异物进入防滑仪器,提高支撑感。
