DE 19852034 C UPAB: 20000531 NOVELTY - A composition for molded body formation comprising polymer lignin, shellac varnish, and natural fibers is new. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the molded body from the composition involving thermal plastification of a dry mixture, which is converted to a molded body in the dry state. USE - The composition is useful in the automobile, building, furniture, packaging, and electronics industries. ADVANTAGE - Poorly friable mixtures can be cold compacted, which avoids thermal stress and odor production. The composition contains no protein, with consequent decreased danger of mold formation, no acid is added, with consequent less wear of processing machines and tools, and no glycols or glycerol, and can be worked at a low temperature.
