JSR breaks through on PLA bioplastics

June 16, 2011 |

In Japan, JSR reports that they have made significant improvements in key properties and characteristics for its polylactic acid-based bioplastic, “BIOLLOY”. The material is showing good results in thin wall applications, which will enable lighter weight product and lead to reduced costs for end users.  The newly-developed “BIOLLOY” has improved compatibility with petroleum-based plastic.

JSR claims drastic improvement in post-molding appearance, shock resistance and formability performance. Compared to existing bioplastics, “BIOLLOY” has five times the shock resistance and greatly improved strength, eliminating the “brittleness” that was considered a weakness of conventional bioplastics. These feature improvements are expected to reduce the amount of resin needed allowing for lighter-weight moldings and  reduced costs.

According to JSR, the combination ratio of polylactic acid can be modified between 5 and 80%, allowing users to achieve a flowability suitable to their processing method, such as injection molding, which is suited for molding complex shapes, blow molding, extrusion and film.  They are expecting their product to be used in a wider range of applications, such as main frames of home electrical appliances, OA devices, exterior components, and automotive interiors where durability and shock resistance are necessary.
