Sumitomo Chemical: Development of light and sturdy transparent resin based on PMMA:
~ Clear shock resistance test of automobile front window ~
Sumitomo Chemical Co., Ltd. has recently developed a transparent resin with high rigidity and high toughness as a substitute for glass and metals as part of the Cabinet Office’s comprehensive science and technology · “realization of ultra thin film and toughening” did.
In recent years, the development of high rigidity / high toughness transparent resin which is thin even with small deflection and is not easily broken is expected in various fields.
PMMA is one of the typical transparent resins.
Among plastic materials, it is known as a resin with the highest level of transparency, high durability and hardness not easily scratched, but on the other hand it is also a material with a property of being easily broken.
In this program, we aim to realize high rigidity and high toughness transparent resin by imparting properties that are difficult to crack while maintaining the merits of PMMA.
