Metabolix Announces New Options for MirelTM Bioplastics

Posted: November 5, 2009

Metabolix announced that Telles, the joint venture between Metabolix Inc. and Archer Daniels Midland Company that produces MirelTM bioplastics, has developed its next generation of injection molding bioplastic, Mirel P1003, in a collaborative effort with Nypro, a leading global precision plastics molder.

Mirel P1003 is the second generation of Mirel for injection molding, replacing both P1001 and P1002 with a single grade suitable for a wider range of applications. This high performance bio-based semi-crystalline polyester is tough, durable, and has excellent resistance to heat, making it a suitable replacement for high performance materials including ABS and polycarbonate. Advanced attributes of Mirel P1003 are overall improved processability, improved flow, faster overall cycle times compared to other biopolymers, and an overall cycle time similar to traditional thermoplastics.

In addition, Metabolix Inc. announced that Telles has collaborated with Teknor Color Company to develop a range of color concentrates for use with Mirel resin. The newly developed color concentrates are formulated using Mirel base resins and meet ASTM D6400 and EN 13432 standards for compostability and biodegradability.

"Teknor developed this series of color concentrates for use with Mirel PHA in direct response to customer demands for a wider range of bioplastic colorants," says John Wood, technical manager with Teknor Color.

The new Mirel colorants are designed to be useful for a wide range of injection molding, sheet, film, and thermoforming applications. Colors are currently being used in the Mirel injection molding grade for laboratory material handling trays, and several colors have been developed for use in consumer retail products. In addition, a black concentrate is currently being used in the Mirel film grade for agricultural mulch film field trials. For more, visit,, and
