A glass-reinforced fluoropolymer composition has increased flexural strength and includes a first fluoropolymer, a second fluoropolymer, and glass fibers. The first fluoropolymer is present in an amount of from 60 to 99 parts by weight per 100 parts by weight of the glass-reinforced fluoropolymer composition. The second fluoropolymer is chosen from (1) a carboxy- and/or anhydride-functionalized perfluoroalkoxy copolymer, (2) a carboxy- and/or anhydride-functionalized poly(ethylene-co-tetrafluoroethylene) copolymer, and (3) combinations thereof. The second fluoropolymer is present in an amount of from 0.5 to 39.5 parts by weight per 100 parts by weight of the glass-reinforced fluoropolymer composition. The glass fibers are present in an amount of from 0.5 to 39.5 parts by weight per 100 parts by weight of the glass-reinforced fluoropolymer composition.

A fluorinated copolymer composition includes a thermoplastic resin A and a fluorinated elastomer B dispersed within thermoplastic resin A. Thermoplastic resin A has a shear stress (&#x3c4;) of greater than 0.11 MPa when measured with a capillary rheometer at a shear rate of 243 secand at 360&#xb0; C. in accordance with ASTM D3835. Fluorinated elastomer B dispersed within thermoplastic resin A has an average dispersed particle size of less than 50 &#x3bc;m.
