NatureWorks LLC Introduces New Injection Molding Grade of Resin: Ingeo 3251D

New Grade Provides an Innovative, “Green” Solution for Consumer Goods Manufacturers

MINNETONKA, Minn., December 17, 2008  --  NatureWorks LLC is launching Ingeo™ 3251D, a new and improved injection molding grade of Ingeo biopolymer. This new Ingeo grade has been designed specifically for the consumer goods segments such as electronics, cosmetics, housewares, toys and custom molding.

This new grade, Ingeo 3251D provides consumer goods manufacturers a sustainable solution in their desire to provide more environmentally friendly products with the performance characteristics of the oil-based plastics used today. This new grade is a compliment to the Ingeo-based compounds currently found in laptops, mobile phones and other consumer goods previously launched by NatureWorks partners.

Ingeo 3251D improves productivity with shorter molding cycles, reducing entry cost, and allowing the same mold and screw use as styrenic’s (GPPS, SAN, HIPS and ABS). NatureWorks also anticipates some injection molders will see potential for down gauging in some applications (e.g. GPPS, SAN).as well as possible energy savings.

Ingeo 3251D is suitable for semi durable applications that:

  • Are either clear or opaque
  • Are currently molded in GPPS, HIPS, SAN, ABS or PET
  • Require impact resistance similar to medium impact polystyrene
