RTP Company (Winona, Minn.) has introduced a line of engineered bio-plastic specialty compounds that use resins derived from rapidly renewable resources. Initial bio-plastic compounds based on polyamide, polyester, and polylactic acid (PLA) are available in grades that provide conductive, flame-retardant, structural, and wear-resistant properties. Developed to meet marketplace requests for alternative green materials, the compounds contain 20 to 80 percent bio-content by weight. Bio-plastic polyamide- and polyester-based compounds are available with glass fiber reinforcement, antistatic protection, halogen-free flame retardant, and PTFE lubrication. Polylactic acid (PLA) grades are combined with PC, PMMA, or ABS in hybrid formulations that increase mechanical performance and offer antistatic, flame-retardant and structural properties. All grades are colorable to standard and custom-matched colors. Prospective applications for bio-plastic compounds include automotive interior and industrial components, semidurable consumer goods, and enclosures for electronics or business equipment.
