PET Aluminum Oxide Film

As a professional high quality PET Aluminum Oxide Film manufacturers, you can rest assured to buy PET Aluminum Oxide Film from Yongyuan and we will offer you the best after-sale service and timely delivery. Polyethylene terephthalate (PET), with the chemical formula (C10H8O4)n, is synthesized by transesterification of dimethyl terephthalate and ethylene glycol or by esterification of terephthalic acid and ethylene glycol. Bishydroxyethyl phthalate, and then polycondensation reaction in the system. It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It is a common resin in daily life and can be divided into APET, RPET and PETG.

It has excellent physical and mechanical properties in a wide temperature range, and the service temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance is poor, and its creep resistance is poor. Denaturation, fatigue resistance, friction resistance, dimensional stability are all very good.

PET Aluminum Oxide Film is a characteristic of aluminum, which is a dense layer of aluminum oxide covering the surface of aluminum, which can prevent further oxidation of aluminum. Aluminum is a relatively active metal with a standard potential of -1.66V. It can naturally form an oxide film with a thickness of about 0.01 to 0.1 microns in the air. This oxide film is amorphous, thin and porous, and has poor corrosion resistance. Alumina membrane is an inorganic membrane, a membrane with high temperature resistance, good thermal stability, high strength and stable chemical properties, which belongs to a membrane separation technology.
