Latest Patents

Davis holds a patent for "Molding of polypropylene with enhanced reheat characteristics." This invention focuses on the formation of bottles, containers, and other articles from polypropylene compositions that include a reheating agent. The use of agents such as antimony, carbon black, and infra-red absorbing dyes allows for a shortened reheating time during injection stretch blow molding or thermoforming. The polypropylene composition with the reheating agent achieves an L* value of at least 80% of the control without added reheating agents, as measured by the Gardner color test. This innovative method may involve the in situ chemical reduction of a metal compound, enhancing the overall efficiency of the molding process.
