Recently, JSFY Microvent Material Technology Corporatio issued an announcement stating that JSFY has invested in the construction of ePTFE functional membrane and hydrogen fuel cell engineering technology research institute, and the 1.5 million square meter hydrogen proton exchange membrane industrialization project has been officially put into production.

The newly built production base has:


ePTFE Functional Membrane and Hydrogen Fuel Cell Engineering Technology Research Institute, with a production capacity of 3 million square meters of hydrogen proton exchange membranes, and a total project investment of 800 million yuan.


The company is the third company in China to realize the commercial production of proton exchange membrane/Perfluorosulfonic Acid Ion-Exchange PFSA Membrane Supplier for Fuel Cell.


About JSFY Microvent Material Technology Corporation


JSFY Microvent Material Technology Corporation is mainly engaged in the research and development, production and sales of microporous materials such as expanded polytetrafluoroethylene membranes (ePTFE membranes) and their modified derivatives, seals and water-retaining membranes.

The ePTFE membrane is a microporous film formed by stretching PTFE after expansion treatment. There are hundreds of millions of micropores per square centimeter of the film. Each micropore has a diameter of about 0.1-1.0 μm, and the size is 1/20000 that of water droplets and 700 times that of air molecules.

Therefore, while preventing the passage of liquid water and dust, the membrane can also ensure the passage of air and water vapor, thereby achieving the function of waterproof and breathable. Products with ePTFE membrane as the core material are ePTFE micro-permeable products. Including breathable plugs, breathable membranes, water pressure-resistant sound-permeable membranes, pressure relief valves, packaging protective gaskets, sound-absorbing and sound insulation products, and gas management products.

Breathable plugs and breathable membrane products are mainly used in automobile lights, wiper motors, ECUs and other parts. Mainly used in automotive, consumer electronics and packaging industries. For example, water pressure-resistant sound-permeable membranes are mainly used in consumer electronics, so that electronic products can reach IP67, IP68 waterproof and dustproof grades; pressure relief valve products are mainly used in new energy power battery packs When the battery pack encounters an impact and other special circumstances that cause the internal pressure of the battery pack to increase rapidly, the pressure relief valve structure will open or be directly damaged, so that the internal pressure of the battery pack will be released quickly and prevent the battery pack from violently expanding or even exploding.

JSFY was the first to undertake the seal order from JSXY Automotive Lighting Technology Corporation [Volkswagen`s China Tie-one supplier of automotive lights] and water-retaining membrane orders from other OEMs to enter the automotive field. In 2011, it successfully developed ePTFE breathable membrane, becoming one of the few manufacturers in China that mastered high-end ePTFE membrane production technology.

In 2013, it successfully entered the supplier system of many industry leaders such as Huayu Vision, Valeo, Magneti Marelli, and Hella Automotive Lighting. In 2017, ePTFE membrane and SiO2 aerogel were compounded into a new type of composite material with high thermal insulation performance, which can be used in many fields such as new energy power batteries, military industry, aerospace and so on. In 2018, the company entered into the field of gas management products such as desiccants and mist absorbents through mergers and acquisitions, and developed CMD products in combination with ePTFE.

At present, the ePTFE microvent material business is the company`s largest business, accounting for about 30%; there are also related to sound absorption (independent processing and production of basic sound-absorbing cotton and ePTFE membrane composite sound-absorbing cotton), gas management products (gas management products are mainly divided into It is two kinds of desiccant and mist absorbent. It can be used in car lights to realize the management of gas humidity in enclosed small and micro spaces), CMD (the company developed CMD products by combining ePTFE membranes with related technologies of desiccants, CMD can systematically solve the condensation problem in small and confined spaces, replacing traditional anti-fog coatings) and mechanical equipment are collectively referred to as the company's core technology products.

The main downstream is composed of automobiles and consumer electronics. The automotive sector can account for more than 85% of the company's total revenue. The core technology products are mainly used in automotive lighting systems.

JSFY's product competitors are mainly Nitto Denko and Gore of the United States, and the company accounts for about a quarter of the Chinese market. The company's ePTFE micro-permeable products are mainly used in the automotive field for breathable plugs and breathable membranes. The main supplier of breathable plugs in China is Nitto Denko, and the main supplier of breathable membranes is Gore.

The company's breathable plugs and breathable membrane products have grown out of nothing, and have gradually replaced Nitto Denko and Gore in the United States. At the same time, the company also took the lead in drafting the industry standard "Waterproof and ventilating components for the protection of automotive electrical and electronic equipment (QC/T979-2014). The company has already occupied a certain market position in the market where the vent plug and the vent membrane are located. Gas management products have gradually replaced the Japanese OZO company`s market share, and the company`s current market share is 8%; CMD`s competitor is Gore, and the company`s CMD products are more cost-effective.

In addition to the automotive market, through continuous R&D investment, the company has formed MEMS acoustic membranes, 30-50 meters high water pressure-resistant acoustic membranes and other products in the consumer electronics field, and formed CMD pressure relief valves and SiO2 aerogel composites in the new energy field. Products such as materials have solved the core pain points of the industry, and these products will help the company's rapid business growth in these two areas.

The first is that the waterproof function of consumer electronics has catalyzed the demand for high water pressure resistant sound-permeable membranes. The company's high water pressure resistant products have entered the supply chain of Xiaomi and Huawei, and passed the test and certification of vivo smart wearable devices.

In the field of new energy vehicles, due to battery safety considerations, the Ministry of Industry and Information Technology has organized and formulated the mandatory national standards of "Safety Requirements for Power Batteries for Electric Vehicles." Provide an alarm signal to reserve a safe escape time for the occupants. The standard will be implemented on January 1, 2021.
