Porous active carbon particles derived from various precursors and polytetrafluoroethylene are used as electrode material and binder material, respectively. Fluoro rubbers such as vinylidene fluoride, hexafluoropropylene, and tetrafluoropropylene can be used as binder. Specific surface area of porous particles is preferably between 2000 and 2500 m /g to obtain high volume capacity. [Pg.230]

As mentioned previously, interest in fluorine-containing copolymers has been particularly concerned with the development of rubbers. Many copolymers have been investigated but the bulk of the commercial production of fluoroelastomers is accounted for by vinylidene fluoride copolymers, of which those with hexafluoropropylene are the most important. Vinylidene fluoride-hexafluoropropylene copolymers were first introduced during the mid-1950 s. [Pg.145]

Other synthetic rubbers used in packaging include ethylene - propylene - diene terpolymers and vinylidene fluoride - hexafluoropropylene copolymer. [Pg.26]

Elastomers examined included NR, nitrile rubber, ethylene-propylene dimer and a vinylidene fluoride - hexafluoropropylene copolymer. Examination of migrating species was carried out by methods discussed in the EC Framework Directive 89/109/ EC (see Chapter 16). Distilled water and diethyl ether extractants were included in this study. [Pg.110]

Copolymerization is an important way to produce properties that are not possible with homopolymers. For example, the homopolymer of vinylidene chloride is highly crystalline, and though it has excellent moisture and oxygen barrier properties, it does not produces very strong film or fiber. Copolymerization with 15 percent vinyl chloride disrupts the regular structure of the homopolymer to produce a stronger, clearer, more flexible material. The copolymer retains much of the barrier properties of the homopolymer and finds wide use for food packaging and filament. Other commercial copolymers include styrene-acrylonitrile, discussed above vinylidene fluoride-hexafluoropropylene, a heat- and oil-resistant elastomer styrene-butadiene rubber ethylene-vinyl acetate hot melt adhesive and 2-ethylhexyl acrylate-vinyl acetate-acrylic acid pressure-sensitive adhesives. [Pg.664]

Fluorinated rubbers, copolymers of hexafluoropropylene and vinylidene-fluorides, have excellent resistance to oils, fuels and lubricants at temperatures up to 200°C. They have better resistance to aliphatic, aromatic and chlorinated hydrocarbons and most mineral acids than other rubbers, but their high cost restricts their engineering applications. Cheremisinoff et al. [54] provide extensive physical and mechanical properties data on engineering plastics. A glossary of terms concerned with fabrication and properties of plastics is given in the last section of this chapter. [Pg.123]

Fluorocarbon Resins. This term includes polytetrafluoroethylene, polymers of chloro-trifluoroethylene (fluorothene), vinylidene fluoride (H2C CF2)j hexafluoropropylene (C3Ffl) and similar compds. These polymers are thermoplastic, inert to chemicals and oxidation. They have high heat stability, retain their useful props at both extremely low and high temps, have high electrical resistance to moisture. The materials are available as re sins, powders, and dispersions, and as films, sheets, tubes, rods and tapes. Some of them are rubber-like. Commercially available varieties are Kel-F , Teflon , Fluorel , Aclar and "Halon ... [Pg.520]

The most important of the above products are the copolymers of vinylidene fluoride and hexafluoropropylene (VF2-HFP), as typified by the Du Pont product Viton A. The terpolymer of these two monmers together with tetrafluoroethylene (VF2-HFP-TFE) is also of importance (e.g., Du Pont product Viton B). This terpolymer is the best among oil-resistant rubbers in its resistance to heat aging, although its actual strengths are lower than for some other rubbers. The copolymers of vinylidene fluoride and chlorotrifluoroethylene (VF2-CTFE) are notable for their superior resistance to oxidizing acids such as fuming nitric acid. [Pg.419]

Piping from plastic tanks may be in aluminium, stainless steel or rigid PVC. Metallic pipework should be used where there exists any serious risk of physical damage. Some fluorinated plastics and rubbers can be used in service with H2O2, for example, polytetrafluorethylene, polyvinylidene fluoride, and a co-polymer of vinylidene fluoride and hexafluoropropylene such as VITON.
