Even though potential memory exists in all TPs, polyolefins, neoprenes, silicones, and other cross-linkable TPs are example of plastics that can be given memory either by radiation or by chemically curing. Fluorocarbons, however, need no such curing. When this phenomenon of memory is applied to fluorocarbons such as TFE, FEP, ETFE, ECTFE, CITE, and PVF2, interesting high-temperature or wear-resistant applications become possible. [Pg.368]

Fluoroplastic FPs have superior heat and chemical resistance, excellent electrical properties, but only moderate strength. Variations include PTFE, FEP, PFA, CTFE, ECTFE, ETFE, and PVDF. Used for bearings, valves, pumps handling concentrated corrosive chemicals, skillet linings, and as a film over textile webs for inflatables such as pneumatic sheds. Excellent human-tissue compatibility allows its use for medical implants. [Pg.427]

Ethylene chlorotrifluoroethylene (Halar) (ECTFE) has excellent chemical resistance to most chemicals including caustic. ECTFE can be used from -105°F (-76°C) to 302°F 150°C). To obtain good extrusion characteristics, this polymer is usually compounded with a small amount of extrusion aid. [Pg.41]

ECTFE is a copolymer of monochlorotrifluoroethylene and ethylene and has, of course, a lower halogen content depending on the monomer ratio. [Pg.475]

It is difficult to make a comparison because each material can be sensitive to different chemicals but, generally, within the service temperatures range, the chemical resistance increases with the amount of fluorine, or halogen total for PCTFE and ECTFE. [Pg.475]

These increase with the fluorine content, or the halogen content for PCTFE and ECTFE (see Figure 4.87(a)). [Pg.478]

ECTFE, being a copolymer of monochlorotrifluoroethylene and ethylene, has a lower halogen content than PCTFE, and the outstanding performances are of a somewhat lower level. On the other hand, it offers easier processing and the mechanical characteristics are better. Crystallinity is generally about 50%. [Pg.507]

ECTFE is handicapped by sensitivity to creep, the price (justified by the performances), density, corrosive and toxic fumes in the event of fire, the limited number of sources and grades. [Pg.507]

ECTFE can be processed by conventional molten-state methods such as extrusion, injection, compression, transfer, rotational and blow-moulding processes. [Pg.508]

ECTFEs are only used for relatively high-performance applications related to heat, low temperature, chemical inertness, electrical insulation. [Pg.509]
