Abstract:
Disclosed herein are biodegradable coating and paint 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:
The present invention relates to composite polymer surfaces which are endowed with antimicrobial and antiviral properties. In the present invention, polymer composites containing additives are obtained, wherein combinations (comprising at least two or more substances) of boron compounds and/or zinc pyrithione made with chlorhexidine gluconate and/or triclosan are used. The invention enables to prevent biodegradation or biocontamination occurring on surfaces. The invention is for controlling the pathogen factors (bacteria, yeasts, fungi and viruses), which are the causes for surface-borne hygiene, allergy and infectious diseases, in sectors (particularly agriculture, health, food and defense) where polymer composites are widely used.
Abstract:
A plastic film is produced by blending a polymer with particles encapsulating an oxidizing agent, such as hydrogen peroxide. Optionally, an “oxodegradable” and/or “oxo biodegradable” additive that promotes degradation of the polymer in the presence of oxygen may be blended into the plastic film. The presence of the oxidizing agent within the plastic film ensures degradation of an article of manufacture, e.g., a plastic bag, when it is disposed of in an anaerobic environment, such as a landfill. In some embodiments, the particles are microcapsules and/or nanocapsules each having a polymer shell encapsulating a core that includes the oxidizing agent. In some embodiments, the particles are microparticles and/or nanoparticles each having a matrix in which the oxidizing agent is encapsulated.
Abstract:
The present invention relates to polymer compositions comprising at least one basic additive, and processes comprising at least one process step to obtain the polymer composition or articles comprising the polymer composition. The polymer composition generally displays an enhanced biodegradability.
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 pharmaceutical compositions comprising 1,3-propanediol and its esters are provided. The 1,3-propanediol and its esters in the pharmaceutical composition are biologically derived, and as such, the pharmaceutical compositions exhibit a low anthropogenic CO2 emission profile.
Abstract:
The present invention relates to a biodegradable resin having outstanding colouring properties, and provides a resin composition which does not give rise to problems such as reduced strength due to colouration. The composition of the present invention, suggests that a PBSAT resin is used as a biodegradable resin, and colouration is performed with same. Also, at this time, the colourant can be mixed in the form of masterbatch. In the present invention, the resin composition is used in the production of various products, in particular monofilament yarn produced via spinning and a fishing net manufactured from same is provided. Fishing nets such as the above are advantageous in that such fishing nets can be realized in various colours in accordance with customer requirements and satisfy the required strength and, after use, degrade naturally in seawater and so do not give rise to problems like environmental pollution.
Abstract:
The use of a composition including at least one saturated free fatty acid and at least one unsaturated free fatty acid as additive, for modifying the mechanical properties of a thermoplastic polymer material. An additivated thermoplastic polymer material and a process for producing same are also described.
Abstract:
A composition for fused filament fabrication may include polylactic acid resin and talc. The composition may range from 50% by weight to 99% by weight polylactic acid resin, and from 7% by weight to 40% by weight talc. The composition may be configured as filaments or pellets adapted to be used in a fused filament fabrication process. A method for generating a resin-based structure may include providing a resin source that may include polylactic acid resin and talc. The resin source may include from 50% by weight to 99% by weight polylactic acid resin, and from 7% by weight to 40% by weight talc. The method may also include heating the resin source to a temperature greater than the melting temperature for semi-crystalline resins or significantly greater than glass transition temperature for amorphous resins, and depositing the heated resin source in a layered manner to form the resin-based structure.
