Paulo Aparecido dos Santos has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8901209
    Abstract: Thermoplastic compositions containing a natural filler and, more specifically, thermoplastic compositions containing a natural filler and having improved thermal and weathering resistance. The wood-plastic composites utilize a cellulose filler, such as wood flour, and vegetal fibers, such as Curauá fiber, as a reinforcement filler. The issues with regard to thermal degradation of cellulose during processing are reduced through the use of specific additives designed to improve its performance during processing. Additionally, other additives are included to improve the UV resistance. Specific combinations of thermal stabilizer and UV additive are provided that enhance the thermal resistance and weathering resistance of the compositions as compared to prior art systems.

  • Publication number: 20130287979
    Abstract: A biodegradable thermoplastic composition includes about 10 to about 80 wt. % of poly(3-hydroxybutyrate); about 10 to about 80 wt. % of a copolymer, wherein the copolymer comprises polypropylene units and poly(3-hydroxibutyrate) units; about 0.5 to about 10 wt. % of a compatibilizer; and about 0.2 to about 10 wt. % of a pro-degradation additive, wherein the pro-degradation additive comprises a transition metal stearate; and wherein the weight percents are based on the total weight of the biodegradable thermoplastic composition. These compositions comply with global standards regarding biodegradable materials and can be used in a wide array of applications, such as cosmetic containers, cell phones, laptops and packaging applications.

  • Publication number: 20120053268
    Abstract: The present invention relates to a process of production of polyamide compounds with natural fibers and polyamide compounds with natural fibers, establishes the fact of using natural fiber to obtain a compound with mechanical properties close to the one obtained with inorganic loads by means of continuous process with extrusion and molding by injection process; the processes presented allows the obtainment, by means of injection, of finished products with precise dimensional and complex features; the fact that the compound with natural Curauá fiber presenting suitable mechanical properties combined to a lesser density than the compound with inorganic load is interesting to the automotive industry as vehicles manufactured with lighter parts consume less fuel.
