Housing Material

Overview

One of issues regarding molding the plastic is balancing fluidity and strength. If the viscosity of the material poured into the mold is too hard, the material will not flow throughout the mold, and if it is too soft, the strength will be weakened.

With virgin plastics, raw materials that suit the material characteristics required by products can be used, but with recycled materials, measures to utilize the characteristics of the recycled materials themselves are required. In particular, it has been very difficult to use plastic with a high percentage of recycled materials for large exterior parts because it is necessary to ensure extremely accurate moldability and strength, as well as the appearance quality such as gloss and color toning.

In order to overcome such issues, with SORPLAS™ the properties of recovered polycarbonates are closely analyzed, and compositions which are aligned to the demands of customers are created through optimal blends of multiple materials. This allows a balance to be reached between fluidity and strength while maintaining a high recycled material content.

Applications

Flat-screen TV housing

As TV design trends toward larger and flat-screened models, the needs for the plastic used in housings and internal parts are changing with the times. To address these needs in a timely manner, we are developing environmentally conscious recycled plastic SORPLAS™.

Some products use SORPLAS™ on the largest part of a TV’s surface, the back cover. Using SORPLAS™ maintains a high finished quality while reducing virgin plastic usage by up to about 50% compared to conventional methods.
