From Material Engineering To Product Innovation
Graphene technology only creates real value when it moves beyond laboratory concepts and becomes reliable, scalable, and repeatable in real products. At XIHE, we build the complete technology pathway — from graphene material engineering and precision manufacturing to graphene electrothermal films, far-infrared performance validation, and product integration.

The performance of graphene-based heating systems begins with precise material engineering. XIHE develops graphene conductive ink formulations with controlled dispersion, conductivity, adhesion, and processing characteristics.
Unlike simple graphene additives or powder-based solutions, XIHE focuses on engineering stable conductive networks that can be integrated into scalable manufacturing processes.
Our material engineering capabilities span graphene dispersion optimization, conductive network design, ink formulation control, printing process compatibility, and electrical performance optimization.

GrantedAdvanced materials require advanced manufacturing. XIHE bridges the gap between graphene material development and industrial production through precision printing, coating, curing, and quality control processes.
Our manufacturing approach focuses on consistent electrical performance, uniform graphene layer distribution, stable thermal output, and scalable production capability.
From laboratory formulation to industrial manufacturing, every process step is designed to ensure repeatability and reliability.
XIHE graphene electrothermal film transforms electrical energy into controlled thermal output and far-infrared radiation through an engineered graphene functional layer.
Designed for flexible integration, the film platform enables manufacturers to develop thinner, lighter, and more adaptable heating solutions.
The graphene layer becomes a controllable energy conversion interface — not a rigid heating element, but a material platform that adapts to product geometry.
Protective Layer
Provides durability and environmental protection.
Graphene Functional Layer
Creates a uniform conductive network for efficient energy conversion.
Electrode Layer
Ensures stable electrical connection and power distribution.
Flexible Substrate
Provides mechanical flexibility for diverse product applications.

Scalable Integration
Compatible with multiple product development scenarios.
In an industry where graphene performance is often discussed through theoretical possibilities, XIHE believes that technology value must be demonstrated through standardized measurement and product-level validation.
Our graphene far-infrared technology is evaluated through recognized testing methods, connecting material performance with real engineering outcomes.
Material-level performance demonstrates possibility. Product-level validation demonstrates reliability. XIHE focuses on the transition from material capability to engineering validation to real product performance.

Developed with scientific and engineering expertise from Jiageng Innovation Laboratory and Xiamen University.
Standard-Based Validation
Performance is supported by third-party testing documentation and a portfolio of granted patents.
Industrial Integration
Integrated capabilities across material formulation, conductive ink, precision printing, coating, curing and roll-to-roll manufacturing.
The XIHE Graphene Technology Platform integrates graphene material formulation, conductive ink development, precision printing and coating, flexible electrothermal film engineering, far-infrared performance validation, and industrial-scale product integration. It is designed to help partners transform graphene-based innovations into commercially viable products.
Graphene conductive ink is used to create electrically conductive patterns and functional layers through printing or coating processes. XIHE develops conductive ink formulations for applications that require flexible electrical and thermal functionality, such as wearable heaters, wellness devices, and smart textile systems.
XIHE graphene film has a measured normal spectral emissivity of ≥0.88 under the test conditions documented in report (2022)WT-HW-00529 conducted by the National Infrared & Industrial Electric-Heating Product Quality Inspection Center / Wuhan Product Quality Supervision & Inspection Institute.
Specific performance in a finished product depends on construction, electrode design, operating conditions, and integration method.
XIHE evaluates graphene heating films through electrical characterization, thermal distribution testing, long-term power-on resistance-drift monitoring, and third-party standard-based testing. Internal benchmark protocols are used for procurement reference and batch consistency evaluation.
XIHE references Chinese industry standards including JG/T 286-2010 for low-temperature electric radiant heating films and GB/T 7287-2008 for infrared radiation heater test methods. XIHE also participates as a contributing drafting organization in the development of the YB/T industry standard for graphene flexible electrothermal film (2024-0923T-YB).
Joule heating efficiency describes how much input electrical energy is converted into thermal energy by electrical resistance. Because almost all electrical energy in a resistive element becomes heat, this value can approach 100% in principle. Electrical-to-radiative thermal conversion efficiency is different: it measures what share of the generated thermal energy is emitted from the film surface as infrared radiation rather than lost through convection or conduction. The 68% value is a radiometric measurement under YB/T 6493-2026, not a statement that 32% of electrical energy is wasted.
XIHE graphene technology can be integrated into smart wearables, heated apparel, automotive thermal comfort systems, wellness and lifestyle products, far-infrared recovery devices, functional textiles, and customized product development programs.
XIHE provides graphene-based far-infrared technology solutions, helping product companies transform advanced materials into reliable commercial products.
