Abstract: In an embodiment, a composition comprises a poly(ester-carbonate-siloxane) copolymer; a nanosilica; a plurality of polysiloxane particles; and a fluoropolymer. The nanosilica can be present in an amount of 1 to 5 wt % based on a total weight of the composition. The nanosilica can have a D50 particle size by volume of 5 to 50 nanometers. The nanosilica can have a hydrophobic coating. The plurality of polysiloxane particles can be present in an amount of 1 to 10 wt % based on a total weight of the composition. The plurality of polysiloxane particles can have a D50 particle size by volume of 0.1 to 10 micrometers. The fluoropolymer can be present in an amount of 0.005 to 5 wt % based on a total weight of the composition.

Abstract: Provided are extrusion dies having entrance, orientation, merging (205), and exit (211) sections, which dies may be used to produce fibers having, e.g., oriented reinforcement materials (e.g., PTFE) dispersed within. The dies provide fibers having enhanced mechanical and processing properties. The orientation section comprises orientation channels (203) wherein a ratio of a cross-sectional area having of the channel inlet to a cross-sectional area of the channel outlet is between 2 and 45.

Abstract: Provided are pre-dynamically cross-linked compositions including a networking additive including a flame retardant species. Specifically, such compositions include a polymer component including a pre-dynamic cross-linked polymer composition. The pre-dynamic polymer composition includes polyester component chains joined by a coupler component, the coupler component including a flame retardant species. A method of preparing a dynamic cross-linked polymer composition includes: reacting a coupler component including at least two reactive groups and a flame retardant species with a chain component including a polyester. The reacting is performed under such conditions so as to form a pre-dynamic cross-linked composition, and is performed in the presence of at least one catalyst that promotes formation of the pre-dynamic cross-linked composition. The pre-dynamic cross-linked composition, when subjected to a curing process, exhibits certain plateau modulus characteristics and has the capability of relaxing internal residual stresses.
