Method for producing porous articles from alternating poly(ethylene tetrafluoroethylene) and articles produced therefrom
10808058 · 2020-10-20 · ·

Poly(ethylene tetrafluoroethylene) (ETFE) polymers having an average molecular weight of at least 300,000 g/mol and a melt enthalpy of at least 57 J/g are provided. The ETFE polymer may include at least one additional comonomer. The ETFE polymer is used to form a porous tape or membrane that has a node and fibril structure. A porous ETFE tape may be formed by lubricating the ETFE polymer and subjecting the lubricated polymer to pressure at a temperature below the melting point of the ETFE polymer. Optionally, the ETFE tape may be expanded at a temperature below the melting temperature of the ETFE polymer to form an expanded ETFE membrane. Alternatively, the ETFE polymer may subjected to heat and pressure without the addition of a lubricant to form a dense preform. The dense preform may be subsequently slit in a length direction and stretched to form a dense ETFE fiber.

Self-bonding fluoropolymers and methods of producing the same
10808054 · 2020-10-20 · ·

A method of making expanded fluoropolymer articles thermally bonds portions of expanded fluoropolymers together, without using an adhesive or crushing force, to produce stronger bonds at the joint between the expanded fluoropolymers than the bonds within the constituent expanded fluoropolymers. The method involves placing the portions of expanded fluoropolymers to be thermally bonded together in intimate contact with each other after wet-stretching the expanded fluoropolymers, and removing the wetting agent used to wet-stretch the expanded fluoropolymers, without subsequent expansion or stretching, to yield an expanded fluoropolymer article exhibiting unexpected and superior properties that can be used in a variety of medical and industrial applications.
