The Zhitong Finance App learned that the Hong Kong Stock Exchange revealed on October 14 that Yingjie Technology R&D Holdings Co., Ltd. submitted a listing application to the main board of the Hong Kong Stock Exchange, with Ping An Capital of China (Hong Kong) as its sole sponsor.

The company is a nanofiber technology developer rooted in Hong Kong, China. It focuses on using nanofiber technology to improve product characteristics and quality, and has launched a product made from a proprietary nanofiber layer — “NASK”. The company relies on the unique properties of nanofibers to manufacture nanofibers with specific material characteristics by adding self-developed additive formulations to polymer precursor solutions and adjusting nanofiber sizes. Furthermore, the company's unique nanofibers use a special structure of “partially gelatinized coarser fibers intertwined with finer nanofibers”, resulting in minimal material consumption and excellent performance. The company has always focused on developing polymer precursor solutions for the manufacture of nanofibers with different characteristics. With technical knowledge in polymer precursor solution development and nanofiber weaving, the company was able to functionalize different materials using proprietary nanofiber layers for various purposes.

On the product side, the company successfully commercialized nanofiber technology applied to respirators, creating its first product — the “NAask” brand. This brand of respirator is a type of PPE and is widely used in medicine and healthcare to control infections by protecting the respiratory tract from airborne chemical hazards. Unlike traditional respirators that are less comfortable and difficult to breathe, the company's breathing apparatus has efficient filtration performance while remaining slim and breathable. At the same time, the company has successfully commercialized four respiratory products, namely N99 respirators, Pro NIOSH N95 respirators, Pro CE FFP2 respirators, and anti-pollution respirators. The company's respirators have proven to have advanced bactericidal efficacy and can kill bacteria (including Staphylococcus aureus and Pseudomonas aeruginosa) in as little as five minutes. Its Pro NIOSH N95 respirator has been approved by NIOSH, while the Pro CE FFP2 respirator has received CE certification and UKCA certification.

According to information, in 2016, the company's first respirator (that is, the N99 respirator) was launched on the market. Subsequently, the company launched Pro NIOSH N95 respirators, anti-pollution respirators, and Pro CE FFP2 respirators in 2017, 2019 and 2020, successfully expanding its product portfolio. The majority of the company's revenue comes from the sale of respirators using nanofiber technology. In 2019, 2020 and 2021 and the six months ending June 30, 2022, the company's revenue from the sale of ventilators accounted for about 63.2%, 99.5%, 99.6% and 99.7% of revenue, respectively. According to industry reports, in terms of revenue, the company ranked second among filter mask respirator brands in Hong Kong in 2021, accounting for 15.2% of the market share.

In terms of R&D, during the track record period, the company developed and designed its respirators and other nanofiber technology application products through its R&D team and cooperation with third-party R&D centers. For each nanofiber technology application product, the nanofiber layer is derived from a polymer precursor solution used for electrospinning. Choosing an ideal solvent or solvent system as a carrier for a specific polymer is the basis for optimizing electrospinning, which can have a significant impact on solution spindability and the morphology of electrospun nanofibers. The company's R&D process begins with strategic and technical pre-research to production and testing of prototypes. Once the polymer precursor solution formula for products using nanofiber technology is determined, the company will carry out product verification, production and quality control, and product sales and distribution.

On the financial side, in 2019, 2020 and 2021 and the six months ending June 30, 2021, the company's revenue was approximately HK$1.9 million, HK$111 million, HK$93.728 million and HK$46.015 million, respectively.
