Oral treatment devices formed from wax-based compositions that are thermally stable when formed into a three-dimensional shape to a temperature of at least 45° C. and plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax. The polymer fraction includes at least one polymer selected such that, when the wax and polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Oral treatment devices are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition and/or an appliance in a user's mouth.

A method enabling the selection, modification and/or creation of polymer materials which can provide improved response to the application of local shear and/or extensional deformation inside the polymer melt in manufacturing technologies including injection molding, injection stretch blow molding, direct injection, extrusion blow molding, sheet extrusion, thermoforming, etc., is provided. A method for manufacturing a polymer article includes injecting or extruding molten polypropylene, polyethylene or polyester based polymer for converting it into semi-final shape while applying shear and/or extensional deformation on the polymer melt. Applying shear and/or extensional deformation on the polymer melt includes selectively modifying the flow path of the molten semi-crystallizable polymer as a function of local pressure profile over at least part of the flow path. Local pressure profile is a function of optimized response of the polymer melt to the applied local shear and/or extensional deformation over at least the part of the flow path.

UV shielding bio-derived furanic polymers (BFP) and UV-shielding composite films containing BFP having another polymer of natural or synthetic origin at varying concentration with high thermal stability, mechanical stability and elasticity are prepared through solvent evaporation casting. A process for preparing BFP having varying physicochemical properties can be carried out via dehydration of various biomass saccharides in different solvents employing various catalysts. The resulting brown-colored films show excellent UV shielding in the region 200 nm to 400 nm and exhibit high optical transparency. The UV shielding efficiency of the film increases with an increase in its treatment temperature. The films are stable and durable in terms of mechanical stability and elasticity even after exposing to harsh conditions without affecting their UV-shielding efficiency.
