  • Publication number: 20190218371
    Abstract: Plastics (e.g., virgin or recycled or reclaimed) are combined with torrefied biomass to create a composite with surprisingly high heat deflection, good mechanical and barrier properties. The composite provides an alternative to conventional composites which contain industrial additives, fillers, and colorants. The torrefied biomass replaces conventional industrial additives and also provides improvement to diminished properties of recycled or reclaimed plastics. The composites described herein can be incorporated into a variety of end products such as cutlery, containers for packaging, hot server items, hard plastic casings, 3-D printed items, and other items.

  • Patent number: 10323144
    Abstract: L-Polylactic acid and D-Polylactic acid biodegradable biopolymers are combined with torrefied biomass and a plasticizer to create a biodegradable cardstock composition. The biodegradable cardstock composition provides an alternative to conventional plastic cardstocks, which are manufactured using petroleum-based materials such polyvinyl chloride (PVC) or polystyrene (PS). The biodegradable cardstock described herein can be incorporated into a variety of end products such as key cards, driver licenses, security badges, calling cards, and other plastic cards, including those that have a magnetic strip containing stored data such as credit and debit cards.

  • Publication number: 20180273746
    Abstract: Stereocomplex biopolymer compositions having tunable and improved mechanical properties and methods of making such compositions are disclosed. The biopolymer compositions include combinations of a matrix-forming polylactic acid comprising an essentially pure enantiomer and a tough polyester to form a polylactic acid matrix. The polylactic acid matrix is further combined with a base polylactic acid comprising an essentially pure opposite enantiomer of the first essentially pure enantiomer of the matrix-forming polylactic acid to form the stereocomplex.

  • Patent number: 9139689
    Abstract: A bioderived plasticizer for biopolymers includes a compatibilizing unit and a polyester plasticizing unit. The plasticizer improves the flexibility of biopolymers while not adversely affecting the modulus of the biopolymer. The compatibilizing unit renders the plasticizer more miscible with the desired base biopolymer, and may increase crystallization and includes a lower alkyl (C3 to C7) organic acid including enantiomeric isomers of the base polymer. The polyester plasticizing unit is formed from monomers comprising a multifunctional alcohol and an aliphatic anhydride or its equivalent dicarboxylic acid and ester derivatives. The polyester plasticizing unit may optionally include one or more difunctional alcohols in combination with the multifunctional alcohol. The resulting bioderived plasticizer lowers glass transition temperature (Tg), can improve brittleness, may increases heat deflection temperature and improves melt viscosity.

The polyester plasticizing unit may optionally include one or more difunctional alcohols in combination with the multifunctional alcohol. The resulting the bioderived plasticizer has a low glass transition temperature (Tg), preferably between ?20° C. to 30° C. The plasticizer is preferably amorphous.

  • Patent number: 7105587
    Abstract: A method and composition for polymer-reinforced composite cementitious construction materials is described. In one embodiment, a crosslinking component is mixed with a high molecular weight strengthening component and an inorganic cementitious material. The addition of the mixture to water causes a crosslinked molecular network to form within the hydrated, composite cementitious construction material. Both enhanced flexural strength and improved nail-pull resistance are shown, allowing a reduction in weight of the composite cementitious construction material compared to cementitious construction materials made according to other known methods.
