The project team will focus on the composite process of aramid fibers and inorganic nanoparticles. By employing molecular-level dispersion technology, the materials can maintain over 85% of their mechanical strength even at 240℃. Preliminary experimental data shows that the breakdown voltage of the modified insulating paper reaches 35 kV/mm, a 40% improvement over conventional products, and its corrosion resistance is significantly better than that of imported silicone rubber materials.
In February 2025, Beijing - Huahao New Materials Technology signed a strategic cooperation agreement with the Institute of Process Engineering, Chinese Academy of Sciences to jointly launch the "Development Project of New High-Temperature-Resistant Insulating Materials," aiming to overcome the technical challenge of traditional materials being prone to aging and cracking in environments above 220℃.

As equipment such as photovoltaic inverters and high-speed rail traction transformers extend their operation to high-temperature conditions, the market demand for high-temperature-resistant insulating materials is growing at an annual rate of over 20%. The head of Huahao's R&D center revealed, "The first batch of samples has completed 500-hour continuous thermal aging tests. Mass production is expected to commence in 2026, with initial production capacity prioritized for strategic customers such as BYD and CRRC Group."
This collaboration has also attracted capital attention. Multiple institutions predict that if Huahao successfully commercializes this technology, it is likely to capture a 15% share of China's insulating materials market within three years, driving the industry to transition from a "price competition" phase to a new stage driven by "technology."
