Fiberglass pultruded profiles have excellent electrical properties: Composite material is excellent in electrical insulating materials for products, mica filler prepared its electrical performance is more excellent, can be used for the manufacture of arc resistance, voltage resistance, induction of superior special parts. The composite materials have excellent electrical properties, the FRP product does not exist the electro chemical corrosion and stray current corrosion, and it can be widely used in the manufacture of insulating parts, motors and electrical instrument in order to improve the reliability of electrical equipment, and prolong its service life. In addition, through the good products in high frequency under the action of microwave dielectric properties and has been used in the manufacture of a variety of radar cover, such as high-frequency insulation products.
The fiberglass products with pultrusion process have excellent corrosion resistance: Resin and composite material is different from ordinary steel, it is not conductive, does not dissolve in the electrolyte solution ion, so it has good chemical stability of the atmosphere, water and acid, alkali, salt and other media, especially in the non-oxidative acid and widely the values of pH have good stability within the scope of the medium. Therefore, the current widely used in the manufacture of corrosion products, for some of the media can not cope with the stainless steel (such as hydrochloric acid, chlorine, carbon dioxide, dilute sulfuric acid, sodium hypochlorite and sulfur dioxide) corrosion, played a good role.
