AQUEOUS POLYTETRAFLUOROETHYLENE DISPERSION COMPOSITION AND USE THEREOF

摘要

The present invention provides an aqueous polytetrafluoroethylene dispersion composition characterized in that the composition comprises 30 to 65 wt. % of polytetrafluoroethylene and a polyoxyethylene alkyl ether in an amount of 2 to 10 wt. % based on the polytetrafluoroethylene, the polyoxyethylene alkyl ether being represented by the formula RO(CH2CH2O)nH wherein R is a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms, and n is 5 to 18, having a cloud point of over 45 DEG C to not higher than 85 DEG C and containing 65 to 70 wt. % of ethylene oxide in the molecule.
