The invention relates to a method for recycling cellulose acetate-containing material, such as a filter tow starting material which consists of cellulose acetate or at least has cellulose acetate. The method has the following steps: supplying a filter tow starting material to a pelletizing press; and pelletizing the filter tow starting material in the pelletizing press in order to convert the filter toe starting material into pellets, wherein the converted pellets have a higher density than the supplied filter tow starting material, and the filter tow starting material, the pellets, and/or intermediate stages of the material are cooled at least temporarily during the pelletizing process.

Thermoformable and biodegradable cellulose acetate compositions comprising at least one cellulose acetate at least one plasticizer, and at least one additional component chosen from a filler, additive, biodegradable polymer, stabilizer, or odor modifier are disclosed. The compositions are formed into films, sheets, and articles.

The present application discloses regioselectively substituted cellulose esters, films made from the regioselectively substituted cellulose esters and methods for making the same. The regioselectively substituted cellulose esters are synthesized using trifluoroacetic anhydride and cellulose with various acyl donors or acyl donor precursors.

The disclosure provides post-production methods for functionalization of optical quality films produced by top tier manufactures. The methods disclosed herein allow for the incorporation of different additives into existing films.

A process is disclosed for combining a cellulose ester polymer with a plasticizer. The cellulose ester polymer is in the form of particles and is combined with a wetting agent and the plasticizer while mixing. The wetting agent dramatically improves the ability of the cellulose ester particles and plasticizer to form a homogeneous mixture. During melt processing, in one embodiment, the wetting agent is volatilized and does not remain in the final product.

The present invention relates to a film for blocking ultraviolet rays that has excellent light resistance, thus exhibiting stable UV blocking performance for a long time, and has a low haze value, and thus is suitable for protecting an organic light emitting device and the like from the external light source.

The present disclosure is directed to examples of housing for a luminaire. In one example, the housing includes a bioplastic base formed to receive a light emitting diode and a driver and a lens coupled to the bioplastic base. The bioplastic base may include a bioplastic and is formed with a non-biodegradable or a biodegradable plastic.

An object of the present invention is to provide a cellulose acetate composition for thermoforming with excellent biodegradability and excellent thermoformability. A cellulose acetate composition for thermoforming containing a cellulose acetate and a glycerin ester-based plasticizer, wherein the cellulose acetate has a degree of acetyl substitution of 1.4 or greater and 2.0 or less, a compositional distribution index (CDI) of 4.0 or less, and a total sulfur content of 15 mg/kg or greater and less than 150 mg/kg.

Disclosed herein are a two-component polyurethane adhesive and a dual cure polyurethane-based adhesive for use in laminated films. The adhesives are particularly useful for producing photochromic and clear-to-polarized laminates for ophthalmic lens applications.

The present application discloses regioselectively substituted cellulose esters, films made from the regioselectively substituted cellulose esters and methods for making the same. The regioselectively substituted cellulose esters are synthesized using trifluoroacetic anhydride and cellulose with various acyl donors or acyl donor precursors.
