We obtained the national-level specialized and innovative small giant certification in 2022. We mainly serve consumer electronics, communication networks, and new energy vehicles.Our company specializes in the R&D of electromagnetic compatibility (EMC) materials, with core products including innovative conductive foam wraps, 3D conformal shielding and heat dissipation films for PCBs, and thermoelectric composite functional film materials. Its conductive foam utilizes adhesive bonding/ultrasonic welding/SMT assembly technologies to achieve import substitution and is applied in consumer electronics grounding scenarios. In May 2025, the company was granted a utility model patent (CN222846656U) for "A Heat-Activated Low-Tack Waterproof Foam Tape," resolving residual copper foil issues in SCF applications.
Johan employees are honest in their conduct and diligent in their work. They work hard and silently contribute to their families and the company. We firmly believe that every employee who takes responsibility for their family will surely produce responsible and good products.
For the past ten years, the Johan brand has been dedicated to electromagnetic shielding functional materials, taking "unceasing service and technology" as its mission, and has become a leader in the innovative materials brand industry.
As an organic whole, Johan Company respects and cares for every member. The same team, the same goal.
Since 2011, Shenzhen Johan has been deeply involved in the fields of EMI/EMC solutions and specialty tapes, and has become an innovative materials leader from China to the world.
