摘要： A polymer composition includes: a matrix polymer component including a polystyrene polymer; and 0.005 wt% to 9 wt. %, based on the weight of the polymer composition, of a fluoropolymer component including a fibrillated fluoropolymer, a fibrillated fluoropolymer encapsulated by an encapsulating polymer, or a combination thereof. The polystyrene polymer has a molecular weight below 193,000 grams per mole (g/mol) as determined according to gel permeation chromatography (GPC) using polystyrene standards. The polystyrene polymer has a Vicat softening temperature above 90 °C as tested in accordance with ISO 306/B50, and the polymer composition has a tensile modulus between 3300 and 3800 Megapascals (MPa) as tested in accordance with ISO 527. Methods for forming the polymer composition include passing a molten feed composition including the matrix polymer component and the fluoropolymer component through a die to form the polymer composition.

摘要： Disclosed herein are compositions comprising: from about 35 wt. % to about 85 wt. % of a polyphenylene ether component; from about 1 wt. % to about 55 wt. % of a polystyrene component; and from about 5 wt. % to about 25 wt. % of a flame retardant agent comprising an aromatic phosphoric ester, wherein the combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition. The composition may exhibit at least a VI flame rating at 1.5 mm measured according to UL 94 (2021) and a dissipation factor less than 0.002 when tested using a split post dielectric resonator and network analyzer.
