Explanation

It is also called polyethylene carbazole. The raw material comes from coal tar, which is made by the reaction of carbazole and acetylene under the action of alkaline catalyst to produce vinyl carbazole, and then by lotion polymerization. Amorphous structure, yellowish or brown transparent glassy solid, relative density 1.20, glass transition temperature 65 ° C, heat deflection temperature 100150 ° C, high heat resistance, water resistance and chemical stability, good electrical performance, large brittleness, elongation>0.3%, water absorption<0.1%, refractive index 1.683-1.70, soluble in ethyl acetate, acetone, benzene, toluene, xylene, tetrahydrofuran, chlorinated hydrocarbon, concentrated sulfuric acid, concentrated nitric acid, insoluble in ethanol, ether Fatty hydrocarbons, mineral oils, castor oil, dilute acids, hydrochlorohydric acids, etc. It can replace mica and asbestos materials as modifier of adhesive. It has excellent high-frequency electrical performance and photoconductive performance, and is mainly used as high-frequency insulating materials, transport layer of copier drum, holographic photographic materials, electrical parts, and chemical anti-corrosion equipment parts used at 120 ° C.
