Abstract
Abstract Here is disclosed a glass fiber product for use in the reinforcement of fluororesin which is improved in the adhesiveness to fluororesin. Thus, a glass fiber product for use in the reinforcement of fluororesin pre-treated with perfluoroalkylsilane represented by the following formula: CF3-CH2-Ch2-SiX3 (X is a hydrolyzable group such as alkoxy groups having 1 to 4 carbon atoms) retains an excellent electrical insulation resistance.
