As a wholly-owned subsidiary of EMT, Henan Huajia New Material Technology Co., Ltd. was established in 2009. The company specializes in the research, development, and manufacturing of metallized films for capacitors ranging from 2.5μm to 12μm. With 13 specialized production lines in operation, the company boasts an annual production capacity of 4,200 tons and possesses comprehensive capabilities spanning from R&D to large-scale manufacturing.
1.Focusing on Seven Key Application Areas
Since its establishment, the company has focused on the R&D and production of metallized films for capacitors in the new energy industry, and is committed to providing customers with customized products and services. Its product applications cover new energy vehicles, centralized and distributed photovoltaics, wind power generation, flexible DC power transmission and transformation, rail transit, pulse-type products, and high-end safety-standard products.
Four Major Product Series
1.1Heavy-edged zinc metallized aluminum film
The product features excellent conductivity, good self-healing performance, strong resistance to atmospheric corrosion, and a long storage life. It is used in capacitors for automotive, photovoltaic, wind power, pulse, and power applications.
1.2Zinc-aluminum metallized film
The product exhibits minimal capacitance decay during long-term use and features a plating layer that is easy to spray gold on. It is mainly used in capacitors for X2, lighting, power, power electronics, home appliances ,and so on.
The product has excellent conductivity, good self-healing performance, strong resistance to atmospheric corrosion, is convenient to store, and has a long shelf life. It is mainly used in capacitors for electronics, lighting, pulse applications, power, power electronics, and household appliances.
1.4Safety Film
Safety film is available in two types: full-width and half-width. It offers the advantages of flame retardancy and explosion protection, high dielectric strength, excellent safety, stable electrical performance, and reduced explosion-proof costs. It is used in capacitors for new energy vehicles, power systems, power electronics, refrigerators, and air conditioners.
