A biodegradable plastic material based on cellulose esters and possibly biodegradable carboxylic acid esters, glycol esters or glycol ethers as softener, composed of from about 50 to about 90 weight percent cellulose ester, from about 5 to about 40 weight percent softener, from about 5 to about 30 weight percent polyester and from about 0.5 to about 5 weight percent AQ-nylon. The biodegradable plastic material may also contain organic acids and/or acid esters and/or ethers different from the softener, and other additives, such as flame inhibitors, and is distinguished by excellent biodegradability, injection molding and blow molding characteristics. Also disclosed are articles made of the material of the invention and methods of making such articles. It is preferably molded into thin sheets and transparent plastic articles, preferably into enclosures/containers for oil lamps, eternal flame oil candles, composition lights, other cemetery light designs, votive lights and thin sheets.

A method of producing elastic foam having a base of polyurethane, in particular for use in the field of automobiles for sound damping. Allows production of foam parts directly in a desired shape in as few operations as possible. The foam is formed from a mixture of at least one polyurethane precondensate, at least on melamine precondensate and further additives for the foaming.
