GEHR Plastics ECO-GEHR® PLA-LF Polylactic Acid
Categories:	Polymer; Renewable/Recycled Polymer; Thermoplastic; Polylactic Acid (PLA) Biopolymer
Material Notes:	PLA-L is a blend of polylactide, lignin, lingo-cellulosic, natural fatty acids, waxes and wood fibers. This material possesses good mechanical properties similar to ABS. This bioplastic has an operating range from -30°c to max 60°C. Properties: Thermoplastic based on renewable raw materials Preparation from environmental friendly raw materials, thus physiologically harmless PLA is biodegradable Disposal by composting resp. incineration. Regional regulations need to be observed. Good mechanical properties similar to ABS High stiffness, modulus of elasticity up to 2740 MPa Good resistance to polar media Applications: Furniture industry Toy industry Mechanical engineering Information provided by GEHR Plastics, Inc.
