Hexafluoropropylene—tetrafluoroethylene copolymers are available in low melt viscosity, extmsion grade, intermediate viscosity, high melt viscosity, and as dispersions. The low melt viscosity (MV) resin can be injection molded by conventional thermoplastic molding techniques. It is more suitable for injection molding than other FEP resins (51). [Pg.359]

Vacuum Outgassing and Permeability. Under vacuum, modified ethylene—tetrafluoroethylene copolymers give off Htde gas at elevated temperatures. The loss rate is about one-tenth of the acceptable maximum rates for spacecraft uses. Exposing 750-pm specimens for 24 h at 149°C to a high vacuum results ia a maximum weight loss of 0.12% volatile condensible material is less than 0.02%. [Pg.369]

Modified ethylene—tetrafluoroethylene copolymers are commercially available ia a variety of physical forms (Table 6) and can be fabricated by conventional thermoplastic techniques. Commercial ETFE resias are marketed ia melt-extmded cubes, that ate sold ia 20-kg bags or 150-kg dmms. In the United States, the 1992 price was 27.9—44.2/kg, depending on volume and grade color concentrates are also available. [Pg.369]

Ethylene—tetrafluoroethylene copolymers respond weU to melt bonding to untreated aluminum, steel, and copper with peel strengths above 3.5 kN/m (20 Ibf/in.). Eor melt bonding to itself, hot-plate welding is used. The material is heated to 271—276°C, and the parts are pressed together during cooling. [Pg.370]

A description of modified ethylene—tetrafluoroethylene copolymers and their classification is given by the American Society for Testing and Materials under the designation D3159-83 (36). A comprehensive listing of industrial and military specifications is avaHable (37). [Pg.370]

Hexachloroethane has been suggested as a degasifter in the manufacture of aluminum and magnesium metals. Hexachloroethane has been used as a chain-transfer agent in the radiochemical emulsion preparation of propylene tetrafluoroethylene copolymer (152). It has also been used as a chlorinating agent in the production of methyl chloride from methane (153). [Pg.16]
