ECTFE films

Other applications include rotomolded tanks and containers for the storage of corrosive chemicals, such as nitric or hydrochloric acid. Extruded sheets can be thermoformed into various parts, such as battery cases for heart pacemakers.58 ECTFE film is used as release sheet in the fabrication of high-temperature composites for aerospace applications. Braided cable jackets made from monofilament strands are used in military and commercial aircraft as a protective sleeve for cables.59... [Pg.85]

ECTFE has good transmission over a wide range of light frequencies. Its index of refraction is 1.4476 at a wavelength of 589 nm. Figures 3.114 and 3.115 show the transmittance of an ECTFE film in the ultraviolet range and ultraviolet plus visible range, respectively. [Pg.100]

To solve this issue, a new Halar ECTFE with special UV scavenger fillers have been recently developed. To demonstrate the effectiveness of this film to protect UV-sensitive materials, the Halar ECTFE film with UV scavengers was laminated on PET and then placed in a QUV test chamber equipped with UV-B lamp centered at 313 nm. Figure 17.4 shows the effect of UV light on PET, that becomes yellowish, while the Halar film with UV scavengers has been able to effectively protect the PET film underneath and appears almost as transparent and uncolored as the sample before UV test. [Pg.398]

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]

Levyt has described a process for orienting fluoropolymer films using a combination of two rolls (Fig. 6.29) rotated at different speeds while the film was heated to a temperature above its second transition temperature, typically between 145°C and 175°C. Roll B rotates at a faster speed than roll A, resulting in the stretch, where the ratio of the speed of roll B to roll A is equal to the stretch ratio (SR). The stretched film was cooled below the second transition temperature of the pol5mier while it was held under tension. Levy reported that orientation in longitudinal direction (LD) imparted improvement in the mechanical property of the film in the transverse direction (TD). Table 6.13 shows the composition of ETFE and ECTFE resins in this study. Tables 6.14-6.16 present the properties of these resins as a function of stretch ratio. A stretch ratio of 0 was indicative of as-cast, unstretched film. Note that in the absence of any stretch in the transverse direction, with... [Pg.215]

Other melt-processable fluoroplastics include ethylene-chlorotrifiuoroethylene (ECTFE) copolymer (melting point 240°C), polyvinylidene fluoride (PVDF) (melting point 170°C), and polyvinyl fluoride (PVF), which is commercially available only as film. [Pg.408]

Similar to perfluoropolymers (see Sec. 11.6.1), ETFE and ECTFE can be foamedf using carbon dioxide. ECTFE resin was formed into a film and placed in the pressure vessel. The vessel was pressurized with carbon dioxide to 6.9 MPa, then heated to 220°C and held at this temperature for 1 hour. Heating the vessel raised the gas pressure to 18 MPa, which was released by venting. The vessel was eooled to room temperature and the film was removed. The appearance of the film turned opaque from transparent due to foaming it had a void eontent of 56%. [Pg.329]

Different methods have been devised to test the bondability of the treated plastic. The specimen can be joined in different ways butt joint, disk joint, and lap shear. An adhesive layer or film is applied to the treated surface, which is then placed against the substrate and heated in a press or oven. The substrate could be a duplicate of the plastic itself. Table 14.1 gives the bond values of fiuoroplastics before and after etching, obtained by the lap shear test method. Bond strengths of the treated surfaces of PTFE, PVF, and ECTFE are larger than that of the untreated surfaces by an order of magnitude or more. [Pg.452]
