Abstract: Provided are methods of manufacturing hollow glass microspheres where a feed composition comprising a glass powder and a blowing agent entrained in the glass powder is introduced into an opening at a first end of a vertically-aligned furnace. Agglomerated glass, unmelted oxides, or natural glassy materials can be used in place of, or in addition to, the glass powder in the feed composition.

Abstract: Provided are compositions comprising a) a fluoroplastic; b) an aromatic material having exactly one hydroxyl group, wherein the aromatic material is free of thiol groups, and wherein the hydroxyl group is bonded to an aromatic carbon; c) a salt former compound capable of forming a salt with the aromatic material; and d) optionally a phase transfer catalyst. Also provided are reaction products of the described compositions, multi-layer articles comprising the compositions and reaction products, and methods for making the compositions, reaction products, and articles.

Abstract: A multi-layer article including a foodware substrate and a fluoropolymer composition having a copolymer consisting of from 80 to 94% by weight tetrafluoroethylene, from 6 to 20% by weight of one or more perfluorovinyl ethers of the formula CF2?CFO(RafO)n(RbfO)mRcf, where Raf and Rbf are independently selected from linear or branched perfluoroalkylene groups of 1-6 carbon atoms, m and n are each independently 0-10 and Rcf is a perfluoroalkyl group of 1-6 carbon atoms, where when the perfluorovinyl ether content is less than 7% by weight, the fluoropolymer has an MFI of 5 or less; and/or a copolymer comprising from 80-94% by weight tetrafluoroethylene, from 5-20% by weight of a perfluorovinyl ether of the formula CF2?CFO(RafO)n(RbfO)mRcf where Raf, Rbf, m, n and Rcf are the same as defined above, and up to 15% by weight of one or more additional monomers based on the total weight of the fluoropolymer.
