Graphene heating management products - graphene heating film

Realized the development and mass production of graphene large-area heating film;

Using the graphene conductive ink formulation independently developed by PMA Group, the ultra-flexible graphene polymer composite conductive film is prepared through standardized process steps, and combined with PI-based flexible circuit board (FPC) technology for packaging to achieve high performance and high reliability;

It has the characteristics of fast heating rate, high heating uniformity, high electrothermal radiation conversion efficiency, softness and high reliability.

Technology R&D Laboratory

PMA Group has the only comprehensive laboratory of graphene heating film in East China, which is also the only comprehensive experiment in East China with full-process R&D capability and small batch production capacity of PI-based graphene flexible heating film and third-generation cloth-based heating film.

The experimental center can undertake the research and development, proofing and testing of graphene flexible heating films of various sizes and shapes, as well as comprehensive evaluation and exploration of graphene heating films in smart wearable apparel products, healthcare products, textile products, medical protective gear applications, smart outdoor products and other fields.
