For Ruihuatai, 2021 was “Refine you to achieve success” Over the past year, Ruihuatai embarked on the “National Demonstration Project for the Industrialization of High‑Tech 1000‑mm‑Wide Continuous Biaxially Stretched Polyimide Film,” and over the past 17 years has forged ahead with determination, boldly shouldering the mission of an industry pioneer. The company has achieved breakthroughs in a comprehensive suite of preparation technologies spanning formulation, process engineering, and equipment, thereby breaking the technological blockade and market monopoly imposed by foreign manufacturers such as DuPont.

Over the course of the year, Ruihuatai achieved notable milestones, including listing on the STAR Market of the Shanghai Stock Exchange and building China’s first dedicated production line for optical-grade CPI.

Deeply cultivating the flexible display industry

Providing a one-stop PI material solution.

Shenzhen Ruihuatai Film Technology Co., Ltd. (hereinafter referred to as “Ruihuatai”) was listed on the STAR Market of the Shanghai Stock Exchange in 2021. It is one of the few domestic enterprises that master the complete set of core technologies—including formulations, processes, and equipment—for high-performance polyimide films and materials. The company has become one of the world’s leading suppliers with the most diverse range of high-performance polyimide (PI) film products, and at the same time… The largest domestic manufacturer specializing in high-performance polyimide films.

As the window of opportunity for the flexible display market opens, Ruihuatai is deeply engaged in the flexible display industry, offering a one-stop PI material solution.

Ruihuatai currently has nine production lines in operation, while the CPI‑specific line at its Shenzhen facility is still under construction.

Among these, Ruihuatai’s top priority for 2021 was to complete the construction of China’s first dedicated production line for optical-grade CPI. According to reports, the entire production process is carried out under cleanroom conditions—class 1,000 for certain stages and class 100 for others—and Ruihuatai aims to finish commissioning in the first quarter of 2022.

A wide variety of products

Key performance indicators are on par with those of foreign companies.

Ruihuatai offers a diverse portfolio of high-performance PI films, with product lines spanning thermal management, electronics, electrical engineering, and other sectors. In addition, the company provides aerospace‑grade PI products for small‑batch sales and CPI films for flexible displays available for sample‑level orders.

According to available data, Ruihuatai currently offers six types of materials for the optoelectronic display sector, each tailored for different applications and structural configurations. CVW products Applied in the cover plate field, CLP product Applied in the touchpad field, TC products and HC products Applied in the fields of transparent circuit boards and smart vehicles, PI/CPI slurry products One is used as the support layer for flexible OLED display TFTs, while the other is designed to accommodate under-display cameras.

In terms of product performance, Ruihuatai’s key performance indicators for its main products are on par with those of leading international companies. Depending on the application field, its products exhibit distinct characteristics, consistently meeting the stringent quality requirements of renowned downstream customers and earning widespread acclaim.

Currently, Ruihuatai The second-generation cover plate, utilizing high-modulus CPI film, has been awarded funding under Shenzhen’s Key Technological Breakthrough Program. R&D has been initiated. Meanwhile, the Jiaxing 1,600-ton high-performance PI film project has seen its next-generation production lines fully enter the manufacturing phase, with several lines expected to begin trial production in the second half of 2022.

Listing on the STAR Market of the Shanghai Stock Exchange

Construction of multiple production lines is progressing in parallel.

Over the course of this year, Ruihuatai’s activities remained focused on the PI film sector:

April 28, Ruihuatai Listed on the STAR Market of the Shanghai Stock Exchange , it plans to raise RMB 400 million for the Jiaxing High-Performance Polyimide Project. According to Ruihuatai, The project plans to establish a new production capacity of 1,600 tons of polyimide film. The main product lines will include thermal‑control PI film, electronic PI film, electrical PI film, and specialty functional PI film, among others. According to Ruihuatai’s announcement, the new construction projects under this initiative primarily include the procurement of equipment such as 1,200/1,600 mm BOPI film production lines and 1,200/1,600 resin synthesis systems.

On June 4, Ruihuatai announced that construction of the plant and associated infrastructure for its fundraising project—the “Jiaxing 1,600-ton High-Performance Polyimide Film Project”—is proceeding at full speed, and production lines have already begun to be customized. It is expected that, starting in the second half of 2022, several production lines will gradually enter the trial‑production phase.

On July 2, Ruihuatai issued an announcement stating that, Company C’s CPI production line is currently under construction and is expected to be ready for commissioning by the end of the year. Ruihuatai stated that the company’s CPI products are primarily used in flexible display screens, including CPI films for foldable screen cover panels. The company will work closely with downstream manufacturers to promote the adoption of domestically produced CPI films in flexible display electronic devices such as foldable smartphones.
On November 2, according to available data, Ruihuatai and Huawei publicly disclosed an invention patent. “A transparent polyimide for flexible optoelectronic applications and a method for its preparation” , Patent publication number: CN113583443A.
