Shenzhen PH functional materials Co., Ltd. was established in 2011. It is a high-tech company who firstly researched and manufactured EMI absorber sheets in China mainland . With the help of advanced material test and research platform of Sichuan University, PH has researched and manufactured A variety of magnetic materials such as EMI absorbing sheets, sintering ferrite sheets, anti-metal magnetic sheets, sendust lamellar powder , soft magnetic ferrite powder,rubber magnet and Thermal conductivity gel. These materials hold the characteristics of absorbing electromagnetic wave, increasing magnetic flux, anti metal interference and isolating magnetic field. Widely used in WPC(wireless charging), RFID, NFC, EMC ,EMI and other fields.
PH has perfect production and testing equipment , professional talent team and a number of independent patent technology. With obvious leading position in the industry, it was selected as the only government funded enterprises in EMI absorber industry by Shenzhen Municipal Science and Technology Innovation Council in 2015. We have passed ISO9001 quality management system certification. Both stable quality and rapid delivery can be supplied. Welcome to inquire!
