Abstract:
Disclosed herein are biodegradable compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said biodegradable composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic CO2 emissions to the atmosphere.
Abstract:
A pumpable shelf-stable suspension of fibers in an organic phase comprising 1.0-60 wt % of fibers and 0.01-10 wt % of a disubstituted urea is proposed as well as a method using the disubstituted urea to suspend fibers in an organic phase.
Abstract:
Biodegradable agricultural compositions comprising 1,3-propanediol and its esters are provided. The 1,3-propanediol and its esters in the agricultural composition are biologically derived, and as such, the agricultural compositions exhibit a low anthropogenic CO2 emission profile.
Abstract:
In the present invention, biodegradable nanocomposites are introduced which include nanoclay particles, titanium dioxide nanoparticles, polyethylene, polypropylene, starch as a biopolymer, maleic anhydride and glycerol. The obtained nanocomposites have very high physical, mechanical and antimicrobial properties. Proper dispersion and distribution of nanoparticles in composite substrate would help in improving the quality of the product to a great extent. The presence of polypropylene next to polyethylene would eliminate the weak points of polyethylene/biopolymer composite as polypropylene helps to modify the physical and engineering properties of nanocomposites in the presence of nanoclay. Titanium dioxide nanoparticles have antimicrobial properties and would result in products which are useful for food and pharmaceutical industries. Another important aspect of this invention is the production of samples in one step by reaction extrusion method.
Abstract:
The invention relates to a biodegradable halogen-free flame retardants composition used for fire-safety and prevention, that limits and extinguishes fires by means of increased resistance to ignition, slowing down burning rates and the rate of heat, smoke and toxic gas release from polymers with different physical and chemical properties and structure, such as textiles, wooden materials, paper, cardboard, corrugated board, leather, cellular polystyrene, foamed polyurethane, and items made of them. The composition according to the invention contains orthophosphoric acid, urea, triethanolamine, ammonia water, polydimethylsiloxane, surfactant, which may be anionic, cationic, amphoteric, non-ionic or mixtures thereof and water.
Abstract:
A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.

Abstract:
Compositions containing 1,3-propanediol and an extraction product are provided, and the 1,3-propanediol in the composition is biologically derived. Also provided are processes for extracting an extract from a source. These processes include providing an ester of 1,3-propanediol and mixing the 1,3-propanediol ester with the source. This serves to extract the extract from the source into the ester. The processes also include separating the source from the ester and extract. Also provided are compositions containing an ester of 1,3-propanediol and an extraction product. In these compositions, the ester can have at least 3% biobased carbon.
