GEHR Plastics ECO-GEHR® CL Cellulose-Lignin Compound
Categories: Polymer; Renewable/Recycled Polymer; Thermoplastic; Cellulosic

Material Notes: C-L is comprised of the wood components cellulose, natural fibers, lignin and fatty acids. It possesses many interesting properties that together are very similar to the natural wood. Consequently, this material is very pleasant to the touch, produces high quality sound and is easily workable. It also has a high degree of rigidity (tensile module of elasticity up to 616 kpsi). Clearly, its advantages compared with grown wood lie in the material's homogeneity. Whereas wood displays density variations resulting from growth rings or imperfections (branches), ECOGEHR® C-L provides an isotropic material texture and reproducible properties. This 100% renewable material is largely neutral in terms of its CO2 balance, and like wood it can be disposed of via decomposition or burning.
