About Us

Shenzhen Johan Material Technology Co., Ltd, founded in 2011, is an innovative material company which focuses on EMI/EMC solution by Shielding & grounding Gasket and customized high-performance tape. 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.
