Title:

FLUOROPOLYMER AND ELECTRIC WIRE AND CABLE BOTH COATED WITH THE SAME

Document Type and Number:

WIPO Patent Application WO/2001/018076

Kind Code:

A1

Abstract:

A fluorocopolymer which comprises tetrafluoroethylene units and hexafluoropropylene units, optionally contains perfluoro(alkyl vinyl ether) units, and has a melt flow rate (MFR) at 372°C of 0.1 to 100 and in which the total amount (ppm) of alkali metals and alkaline earth metals contained therein is not larger than the value as calculated from the melt flow rate at 372°C (MFR) using the equation (1): 5.2 x e?0.125(MFR)¿ + 2 but exceeds the value as calculated using the equation (2): 0.35 x e?0.125(MFR)¿. An electrical wire or cable coated with the fluoropolymer retains the intact electrical properties of the electrical wire and does not suffer core wire corrosion, despite the presence of alkali and alkakine earth metals.
