GEHR Plastics ECOGEHR® PLA-WF Polylactic Acid, 30% Wood Fibers (discontinued **)
Categories:	Polymer; Renewable/Recycled Polymer; Thermoplastic; Polylactic Acid (PLA) Biopolymer
Material Notes:	PLA-WF is a composite material of polylactide, a small amount of a petroleum-based polyester and wood fibers (30%). It possesses high mechanical strength thanks to the excellent binding of the wood fibers and the polymer blend. This is comparable with standard fiber-reinforced polymers. It also displays good thermal insulation and conforms to the standards governing toys. Information provided by GEHR Plastics, Inc.
