  • Patent number: 11780986
    Abstract: The present invention provides methods for reducing extractables from plastic articles made from recycled plastic. The method includes the steps of: (a) providing a plastic article in a chamber; and (b) providing a fluorination gas in the chamber, thereby exposing the plastic article to the fluorination gas. The method results in the reduction of the extractables from the plastic article.

  • Patent number: 11014999
    Abstract: A method for removing perfluorinated compounds from a fluoropolymer material is provided. The method includes the steps of: (a) providing the fluoropolymer material in a chamber; (b) providing an anaerobic environment in the chamber; and (c) providing a fluorination gas in the chamber, thereby exposing the fluoropolymer material to the fluorination gas. The method results in the removal the perfluorinated compounds from the fluoropolymer material.

  • Patent number: 11359065
    Abstract: A method for the direct fluorination of plastics and articles made from plastics is presented. The novel method includes ensuring extremely low oxygen and moisture content in the chamber before the primary fluorination step, ramping the fluorine concentration during the fluorination step, and providing a quenching step for improved shelf-life. Containers processed by the novel method demonstrate a marked improvement in barrier properties for organic solutions.
