Core technology: Composition development technology

Polypropylene composites have a wide range of applications in industrial material components that require high strength, high impact strength, and durability.
In the automotive field, in particular, the need to "reduce weight" ⇒ "improve fuel/electricity costs" ⇒ "reduce CO2 emissions" has led to the application of this material to bumpers, instrumental panels, door trims, and under-hood parts, and more recently to back doors, fenders, and other external automotive parts that previously used metal or engineering plastics.
In the development of polypropylene composite materials, we will continue to propose and provide high-performance, high-quality materials that meet the needs of customers and society and reduce environmental impact through our original fundamental, commercialization, and mass production technologies.
