Conventional optical frames made of plastic had a defect of low form stability. 　We developed “carbo-titan” as the new material suitable for optical frame through the process of our application and improvement by blending carbon fiber and reinforced resin followed by blending of titanium etc. into this compound as the reinforcing agent according to our original ratio. This “carbo-titan” has the properties of lightweight and high-intensity and excels in heat resistance, durability, corrosion resistance, and form stability. Thus, we succeeded in eliminating the defect of conventional plastic material.

従来のプラスチック素材の眼鏡フレームは形態安定性が低い欠点がありました。当社は、炭素繊維を、強化樹脂と混合、コンパウンド化したものに、強化剤としてチタン等を独自の比率で混合し、メガネフレーム用に適した素材として応用・改良した「カーボチタン」を開発。この「カーボチタン」は軽量で高強度を誇り、耐熱性、耐久性、耐食性、形態安定性に優れ、従来のプラスチック素材の弱点を解消することに成功しました。
