my country's demand for polarizers continues to grow, and there is huge room for domestic substitution in the market

Polarizer is one of the important materials for liquid crystal displays. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple processes of compounding, stretching, and coating. Achieve high brightness and high contrast characteristics of liquid crystal display.
There are many types of polarizers, which can be divided into TN polarizers, STN polarizers, TFT polarizers and OLED polarizers according to different application fields; according to different functions, they can be divided into transmission polarizers, compensation polarizers, and reflective polarizers. Polarizers, semi-transmissive and semi-reflective polarizers, etc.; according to different polarizing materials, they can be divided into metal polarizing films, dye-based polarizing films, iodine-based polarizing films, polyethylene polarizing films, etc.
The upstream of the polarizer industry chain is the supply of raw materials and production equipment such as polyvinyl alcohol, pressure-sensitive adhesive, release film, and stretchers; the midstream is the production of various products; the downstream is widely used in sunglasses, anti-glare glasses, and liquid crystal displays. , optical lenses, nanomaterials, automotive window films and other fields.
According to the “China Polaroid Industry Market Survey Research Report 2023-2027” released by the Industrial Research Center, with the development of my country’s economy The level continues to improve, Internet technology continues to advance, coupled with the continuous growth of national disposable income, the continuous increase in the penetration rate of smartphones, computers, automobiles, etc., and the continuous expansion of the scale of display panels and other industries, driving the continuous expansion of the polarizer market. In 2019, my country’s polarizer market size was approximately 3.7 billion yuan. It is expected that the market size will exceed 7 billion yuan in 2023, with a compound annual growth rate of more than 17% from 2019 to 2023.
The production process of polarizer is complex and has certain technical barriers. The foreign polarizer industry started early and has a long development time. It has strong competitive advantages in production technology, industry scale, brand awareness, product quality and variety, and occupies most of the domestic market share. The domestic polarizer industry started late, has insufficient production capacity, is highly dependent on foreign products, and has large room for domestic substitution in the market. From the perspective of industry competition, Sumitomo Chemical ranks first with a share of more than 25% in the domestic polarizer market, Nitto Denko ranks second with a share of nearly 20%, Shanshan Co., Ltd. and LG Chem both share a share of 20%. About 10%, of which Sumitomo Chemical, Nitto Denko, and LG Chem are all foreign brands, accounting for more than 50%. Local companies still have considerable room for development.
Industry analysts said that from the perspective of downstream market demand, with the continuous development of our country’s economy and the continuous improvement of national living standards, consumer electronics , 3D glasses, etc., demand will continue to grow; epidemic prevention and control policies are opening up, the tourism economy is gradually recovering, and ice and snow sports, camping and other industries are developing rapidly, and the demand for goggles, sunglasses, etc. is growing, and polarizers have a broad consumer market. At present, the market share of domestic polarizer products is relatively small. Domestic manufacturers still need to increase capital investment and research and development efforts, continuously improve production technology and product quality, and enhance their core competitiveness.
