The present invention relates to water-resistant, thermoplastic starch materials processable into environmentally safe, thermoplastically produced products and cast sheets, which consist of starch acyl compounds, obtainable from high amylose starches and the derivatives thereof and being sparingly soluble in water, and of plasticizers which like ethyl citrate, glycerol acetate and lactic acid ester have a gelatinizing effect and preferably a dissolution property resulting in brilliant transparence and, as can be proved, are biodegradable.

Water-resistant starch materials for the production of cast sheets and

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.

Special amyloses and their use for producing biodegradable plastics

Water-resistant, thermoplastic starch materials which are processable into environmentally safe, thermoplastically produced products and cast sheets. They consist of starch acyl compounds, obtainable from high amylose starches and their derivatives (being sparingly soluble in water), and of plasticizers (like citric acid ethyl ester, glycerol acetate and lactic acid ester), which have a gelatinizing effect, and preferably, a dissolution property resulting in brilliant transparence and, as can be proved, are biodegradable.

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.

A method of joining wood material and plasstic material. An anchoring layer is applied to the area of the wood material that is to be joined to the plastic material and adhesively joined to the respective area which has a high specific surface area and with which the plastic material is joined by injection molding. The resultant composite material can be used in particular in the furniture sector and in housing construction, where low-cost and stable veneered plastic parts can be produced by the method, which can be made fire-proof by using appropriate plastic materials. Additional fields of application are the automobile industry, the construction of campers and boats, and aircraft construction. The wood material that is mainly used is veneer wood, because of the high quality of the visible surface of the composite.

Method of joining wood material to plastic material

A method for the surface modification of objects made from polyvinylidene fluoride by dehydrofluorinated of the surface of the objects. The dehydrofluorination is carried out with an etching solution which, in addition to a strong basic compound and a swelling agent and/or solvent for polyvinylidene fluoride, contains an auxiliary agent for the homogenization of the etching solution. The effect of etching is supported by an adhesion promoter. High resistance to shearing and good tough-elasticity in composite structure and laminates is achieved.
