  • Publication number: 20200147852
    Abstract: A method of manufacturing a semi-crystalline article from at least one pseudo-amorphous polymer including a poly aryl ether ketone, such as PEKK, including a softening step, wherein the at least one pseudo-amorphous polymer is heated to a temperature above its glass transition temperature to soften the polymer, and a crystallization step, wherein the at least one pseudo-amorphous polymer is heated to a temperature between its glass transition temperature and melting temperature, the pseudo-amorphous polymer being placed on a mold during either the softening step or the crystallization step before at least some crystallization takes place. The method results in articles demonstrating increased opacity, increased crystallinity, increased thermal resistance, improved chemical resistance, and improved mechanical properties over articles formed by traditional thermoforming processes.

  • Patent number: 8377354
    Abstract: The invention relates to a method of producing a film comprising at least one layer of a thermoplastic fluoro-polymer and at least one layer of another polymer (A). The inventive method consists in using extrusion blow molding to coextrude a fluoro-polymer and polymer (A) which adhere to one another; with a layer of another thermoplastic polymer (B) such that it forms a layer which is adjacent to the fluoropolymer/polymer (A) layer According to the invention, the thermoplastic polymer (B) is incompatible with the fluoro-polymer and polymer (A) and has adequate extrudate behavior to support the layers of fluoro-polymer and/or polymer (A). Once the coextrudate has been cooled, by separating the layer(s) of (B), at least the film is recovered, said film comprising at least one layer of a polymer selected from among thermoplastic fluoro-polymers and polymers (A).
