要約
(EN) A resin composition for coating optical fibers includes a base resin, that contains an oligomer including a urethane (meth)acrylate oligomer, a monomer, and a photopolymerization initiator, and hydrophobic inorganic oxide particles. A resin film obtained by curing the resin composition at an integrated light intensity of from 900 mJ/cm2 to 1100 mJ/cm2 has a break elongation of from 2.5% to 50% at 23°C and a Young's modulus of from 1150 MPa to 2700 MPa at 23°C.
(FR) Une composition de résine pour le revêtement de fibres optiques comprend une résine de base, qui contient un oligomère comprenant un oligomère de (méth)acrylate d'uréthane, un monomère, et un initiateur de photopolymérisation, et des particules d'oxyde inorganique hydrophobes. Un film de résine obtenu par durcissement de la composition de résine à une intensité lumineuse intégrée de 900 mJ/cm2 à 1100 mJ/cm2 a un allongement à la rupture de 2,5 % à 50 % à 23°C et un module de Young de 1150 MPa à 2700 MPa à 23°C.
(JA) 光ファイバ被覆用の樹脂組成物は、ウレタン(メタ)アクリレートオリゴマーを含むオリゴマー、モノマー及び光重合開始剤を含有するベース樹脂と、疎水性の無機酸化物粒子とを含み、該樹脂組成物を900mJ/cm以上1100mJ/cm以下の積算光量で硬化させた樹脂フィルムの破断伸びが23℃で2.5%以上50%以下であり、ヤング率が23℃で1150MPa以上2700MPa以下である。
