Product application: Mitsubishi Chemical launches a biological based (PC) ballpoint pen
Mitsubishi Chemical Company (Tokyo, Japan) recently announced that its biological based engineering plastic "DURABIO" ™” It has been adopted as the main body (rear axle) of the Pilot Corporation (Tokyo, Japan) ballpoint pen "Acroball T Series Bioplastic" and "FRIXION Ball Knock 05 Bioplastic".
DURABIO ™ It is a biological based polycarbonate resin mainly derived from plant based isosorbitol. Compared to traditional polycarbonate resin (hereinafter referred to as PC resin) made of bisphenol A (hereinafter referred to as BPA), DURABIO ™ It has high transparency, excellent optical properties, and excellent scratch resistance. Its puncture impact performance is equivalent to that of PC resin. DURABIO ™ It is a plant derived polymer, but it is not biodegradable. It has excellent durability and can be deployed in a variety of applications, such as optics, energy related components, alternatives to high-performance glass components, electronic devices, automotive enclosures, interior and exterior decoration.
DURABIO ™ Non biodegradable, this new bio-based polycarbonate can be used in a variety of applications due to its excellent durability.
Due to DURABIO ™ Using plant-derived raw materials, it has a unique and important alicyclic (non aromatic) framework, and therefore has excellent optical properties. Its transparency and optical uniformity exceed those of PC resins based on BPA.
In addition, due to exposure to light, the yellowing can be negligible and can be widely used in applications that require photostability. This is naturally beneficial in transparent applications, even for applications that require light colored materials, there is almost no need to worry about color changes due to yellowing.
In addition, DURABIO ™ It retains high surface hardness characteristics and has significantly improved wear resistance compared to PC resin. Excellent surface impact strength. Even under the condition of brittle fracture of acrylic resin, DURABIO ™ It also exhibits the same ductile fracture as PC resin. The impact performance is equivalent to that of PC resin.
Another advantage is excellent tone design ability. Excellent transparency makes it possible to create extremely bright colors in transparent materials. Can produce metallic coloring qualities and deep tones.
