Acid-resistant films (acid-resistant films) are mainly used in the glass etching process. There are only a small number of companies in my country.

Acid-resistant film, also known as acid-resistant film and acid-resistant protective film, refers to a thin film material with a special chemical structure. It has excellent acid resistance, weather resistance, corrosion resistance, and moisture and heat resistance. It can be used in various applications that require resistance to acid. Fields of environmental erosion include the chemical industry, glass manufacturing, panel manufacturing, electronic equipment manufacturing, food processing, etc.

Acid-proof film is a film made of high molecular polymer as the base material and coated with special adhesive. Among them, polymer materials commonly used in the production of acid-resistant membranes include polyester (PET), polytetrafluoroethylene (PTFE), polyimide (PI), fluorinated polymers, etc. These materials have excellent chemical stability With low permeability, it can effectively isolate acid corrosion. As a major country in the chemical industry, my country’s current output of polymer materials is continuing to increase under the background of continuous technological upgrading of local chemical companies, which is beneficial to the development of the acid-resistant membrane industry. Taking PTFE as an example, domestic PTFE production will exceed 90,000 tons in 2022.

According to the “2023-2028 Acid-Resistant Film (Acid-Resistant Film) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center shows that the acid-resistant film has excellent acid resistance and is mainly used in the glass etching process. Glass etching refers to the process of engraving text or patterns on the surface of glass. In this process, acid-resistant films are mainly used in ITO glass, touch panel OGS process, and COVER LENS glass cover chemically strengthened acid etching process protection scenes. .

Take the ITO glass market as an example. ITO conductive glass is a type of high-tech product that can be widely used in semiconductor device manufacturing scenarios such as display panels, photovoltaic cells, and transparent circuit boards. In 2022, my country’s ITO glass market shipments will exceed 600 million pieces, a year-on-year increase of over 15%. Under the current background of rapid development of the domestic ITO glass market, the demand for acid-resistant films is continuing to increase, and the industry has good development prospects.

At present, the main companies in my country’s acid-resistant film market include Shenzhen Mingchengtai Technology, Shenzhen Guocheng Technology, Shenzhen Yunzhi Electronics, Weisi New Materials Taizhou, Kaisheng Technology, Huizhou Chuangshi Industrial, Guanshi Xinhongke Adhesive Products, etc. . Acid-proof membranes have certain technical barriers, and the number of companies in this field in my country is still relatively small. In the future, as the market development prospects continue to highlight, its competitiveness is expected to gradually strengthen, and the industry has broad room for growth.

Industry analysts said that acid-proof film is a type of film that can be widely used in various applications that need to resist acidic environments. An important membrane material in the field of corrosion, especially in the field of glass etching. At present, acid-proof film has become one of the important materials required for the production of ITO glass. Currently, against the background of the continuous increase in domestic ITO glass production, its demand continues to increase, and the industry development prospects are good. However, the number of domestic companies entering the acid-proof film market is still relatively small, and the industry still has hugeroom for growthin the future. .
