性能に悪影響を及ぼさない。In particular, when chlorinated polyethylene having an IO of 38 or more is used as the coating material, the resin component of the chlorinated polyethylene has little tendency to migrate to the optical fiber over time, and does not adversely affect the light transmission performance of the optical fiber.
また、塩素化ポリエチレンが、炎に接してもドリップし
ない特性を有するので、シート自体のドリップを未然に
防止する。Furthermore, since chlorinated polyethylene has the property of not dripping even when exposed to flame, dripping of the sheet itself is prevented.

（１） Ｐｉ素素数数大きい窩難燃性の樹脂を被覆材
に用いるので、難燃性に優れている。(1) Since a flame-retardant resin with a large Pi prime number is used for the coating material, it has excellent flame retardancy.
（２） 特に、酸素係数３８以上の塩素化ポリエチレン

イバ内部に移行しないので、ファイバ性能を劣化させる
ことがない。(2) In particular, when chlorinated polyethylene with an oxygen coefficient of 38 or more is used as the coating material, the resin component does not migrate into the optical fiber over time, so the fiber performance does not deteriorate.
（３） 炎に接したときに光ファイバシートをドリップ
させることがなく。(3) The optical fiber sheet will not drip when exposed to flame.
（４） 塩素化ポリエチレン被覆材を用いたとき、その
の機械特性から、コネクタとの嵌合性に優れている。(4) When a chlorinated polyethylene covering material is used, it has excellent fitability with a connector due to its mechanical properties.
