Industries such as 5G communications, new-energy vehicles, and aerospace are undergoing rapid technological iteration, driving electronic devices toward higher speeds, miniaturization, and higher-density integration. Electromagnetic Interference (EMI) This has also become a core pain point that constrains the stability and safety of devices. Industry data indicates that by 2035, the global electromagnetic compatibility shielding market will exceed US$18.3 billion, with significant demand from consumer electronics, automotive electronics, aerospace, and military sectors. Electronics has emerged as a core growth driver, with surging demand for high-performance electromagnetic shielding materials.

On this invisible battlefield of electromagnetic protection, conductive silicone rubber and conductive ink are the core protective materials that perfectly align with modern electronic designs emphasizing thinness and flexibility. Betely leverages… From in-house R&D of conductive powders to mass production of finished products Leveraging core capabilities across the entire industry chain and integrating two major product‑technology pathways, we provide customers in various sectors with end-to-end, customized comprehensive solutions for electromagnetic shielding materials.
Two core product formats precisely address and shield against all‑scenario requirements.
To meet the electromagnetic shielding and structural‑compatibility requirements of diverse industries and equipment, Betely has developed two distinct core products, providing comprehensive solutions to a wide range of electromagnetic compatibility challenges.
I. Conductive Silicone Rubber: An Integrated Solution for Sealing, Protection, and Electromagnetic Shielding

Betely conductive silicone rubber is formulated with high‑quality silicone elastomer as the base, modified with high‑performance conductive fillers, and innovatively combines the elastic sealing properties of rubber with highly efficient electrical shielding capabilities.
The product can be processed into various forms—extruded strips, molded sheets, custom‑molded components, and modified compounded rubber—according to customer requirements, providing a one‑stop solution for a wide range of electronic devices. Electromagnetic compatibility protection + environmental sealing protection A dual challenge, designed to adapt to complex operating conditions across multiple scenarios.
II. Conductive Ink: Ultra-thin, Lightweight Electrical The child’s invisible protective film

In response to the protective needs of lightweight, flexible, and precision electronic devices, Betely has launched Copper foil conductive black ink, This product employs a proprietary two-component reactive curing technology, achieving an ultra-thin dry film thickness of just 4–5 microns while delivering an exceptionally low surface resistivity of ≤40 mΩ. It provides highly efficient and stable electromagnetic shielding, all while offering a refined, uniform black decorative finish that balances functionality with aesthetic appeal.
In terms of durability and compatibility, this conductive ink delivers exceptional performance: it withstands at least 500 alcohol‑wipe cycles and reliably endures a rigorous environmental test—60°C and 90% RH—for 72 hours, maintaining stable, unimpaired performance. It is fully compatible with high‑speed coating lines in modern electronics manufacturing, meeting the demands of large‑scale production.
End-to-end in-house R&D and control, strengthening the product’s core competitiveness.
Unlike most companies in the industry that focus on a single link in the value chain, Beteli’s core strength lies in seamlessly integrating Conductive powder—surface coating—formulation development—mass-production process—full‑product validation A fully closed-loop technological chain that controls product quality and performance at the source, ensuring technological self-reliance, process controllability, and traceable quality.
1. Self-developed, controllable conductive silver powder
Powder is the core substrate of conductive materials. Betely has achieved independent R&D and large-scale production of conductive silver powder, enabling precise control over particle size distribution and micro‑morphology. As one of the few companies in the industry with end-to-end R&D capabilities spanning silver nitrate feedstock processing, silver powder synthesis, and slurry modification, the company had accumulated a total of 121 invention patents as of June 2026. Precisely controllable powder morphology enables the efficient formation of a uniform and stable conductive network, thereby ensuring the material’s shielding performance at the source.
2. Precision Surface Coating Process
Leveraging a mature, precision silver-plating process, it can form a uniform, dense, and strongly adherent coating on the surfaces of various substrates, including copper powder, glass microspheres, and aluminum powder. This high‑quality coating technology significantly enhances the oxidation resistance and salt‑spray resistance of conductive fillers, effectively extending the service life of conductive silicone rubber products and ensuring long‑term, stable equipment operation.
3. Refined Formula Development
In the field of silicone materials, Betely has built up extensive technical expertise, deeply investing in the R&D of high‑end silicone rubber formulations—ranging from medical‑grade to flame‑retardant and thermally conductive grades. For electromagnetic shielding applications, the team precisely matches conductive fillers with a silicone rubber matrix, iteratively fine‑tuning and optimizing the formulation to strike an optimal balance across multiple performance metrics, including electrical conductivity, elasticity and toughness, structural strength, and compression set, ensuring the product meets the demands of diverse and complex use cases.
4. Quantitative Production Control
In the mass-production phase, Betely implements standardized, quantified control across the entire production process—including mixing, vulcanization, and molding—rigorously managing the parameters of each step to ensure consistency across different batches. Consistent product performance and traceable quality. Leveraging mature, large-scale production capacity for specialty silicone rubber, we can efficiently meet customers’ needs for high-volume, regular supply.
5. Full-Cycle Experimental Validation
The company is equipped with state-of-the-art, fully integrated laboratories that enable end-to-end validation across the entire product lifecycle—ranging from raw material sampling and in-process inspections to comprehensive performance testing of finished goods. These capabilities encompass key metrics such as volume resistivity, electromagnetic shielding effectiveness, mechanical properties, and environmental aging tests, ensuring rigorous quality control throughout the entire process—from R&D and pilot production to mass manufacturing.
