Hongchang New Materials: Advancing Thermal-Field Insulation and Flow Battery Materials for a Low-Carbon Future

As Industry 4.0 continues to transform global manufacturing, and as China steadily advances its “Dual Carbon” goals, strategic emerging industries are entering a period of rapid growth. The demand for high-end manufacturing, advanced materials, photovoltaic technology, semiconductors, and energy storage solutions is stronger than ever.

Against this backdrop, Hongchang has positioned itself as a specialist in thermal-field insulation products and core materials for flow battery energy storage. With a focus on technology, industrial scale, and sustainable development, the company provides integrated solutions for customers worldwide.

A Company Built on Technology and Industrial Growth

Hongchang’s development began in 2008, when China’s carbon fiber industry was still in its early stages. At that time, the Carbon Business Division of Hunan Haixin New Materials Co., Ltd. was established, focusing on carbon fiber research and development.

In 2014, as the industry entered a phase of rapid expansion, Anhui Hongchang New Materials Co., Ltd. was founded. The company became one of China’s early manufacturers engaged in the research, development, and production of rayon-based carbon fiber felt. It also established China’s first continuous production line for carbon fiber graphite felt.

In 2022, the company completed its shareholding reform and officially became Anhui Hongchang New Materials Co., Ltd. Its production capacity ranked among the highest in China’s domestic industry. From 2021 to 2023, Hongchang achieved three consecutive years of doubled production capacity, sales, and profit. Its felt product sales also ranked first in its domestic market segment.

In 2024, the company submitted its listing application, marking a new stage of high-quality development.

More Than a Decade of Industry Expertise

After more than ten years of focused development, Hongchang has earned several major honors, including recognition as a National High-Tech Enterprise and a National “Specialized, Refined, Distinctive, and Innovative” Little Giant Enterprise.

The company has also passed six major system certifications and established two wholly owned subsidiaries: Anhui Hongyi New Materials Co., Ltd. and Inner Mongolia Hongchang New Materials Co., Ltd.

To strengthen its long-term competitiveness, Hongchang has developed a strategic structure described as “one body with two wings”: photovoltaics, semiconductors, and energy storage. This development model continues to support the company’s leading position in advanced materials.

Strong R&D Capabilities and Standard-Setting Expertise

Hongchang covers more than 600 mu of land and operates an industrial base of nearly 300,000 square meters. The company works with a research team led by Professor Huang Qizhong of Central South University, a well-known expert in carbon materials.

Supported by platforms such as a provincial postdoctoral research workstation and a provincial enterprise technology center, Hongchang has attracted and trained a large number of industry professionals.

To date, the company has obtained 13 authorized invention patents and 24 utility model patents. It has also participated in the formulation of nine national standards, led the development of two group standards, and contributed to three green design product evaluation standards.

Through continuous technical innovation, Hongchang is helping shape industry standards for advanced carbon-based materials.

Intelligent Manufacturing and Integrated Production Capacity

Today, Hongchang is building its core competitiveness around scientific research and advanced technology. The company has developed leading intelligent and digitalized production workshops in China.

Its production system includes:

• 10 needling production lines
• 30 pre-oxidation production lines
• 10 carbonization production lines
• 20 integrated carbonization and graphitization production lines
• 18 vacuum furnaces

This enables Hongchang to maintain complete production capabilities across needling, pre-oxidation, carbonization, graphitization, and finished product manufacturing.

The company’s annual production capacity can reach 8,000 tons of thermal-field insulation materials, along with 60,000 quartz crucibles and quartz guide tubes.

Advanced Materials for Photovoltaics, Semiconductors, and Energy Storage

Hongchang is committed to supporting the development of photovoltaics, semiconductors, and new energy storage industries.

Its independently developed carbon fiber products have helped reduce dependence on imported materials in high-tech carbon fiber applications. With advantages such as low ash content, high temperature resistance, and low thermal conductivity, these products provide advanced thermal insulation solutions for multiple industries.

The company has also introduced complete advanced production lines for quartz products. Its quartz crucibles, quartz guide tubes, and other quartz products offer high purity, high temperature resistance, and long service life.

In addition, Hongchang has developed carbon fiber felt products specifically for flow battery electrodes. These materials offer strong stability, corrosion resistance, and high electrical conductivity, making them suitable for energy storage applications.

A Diverse Portfolio of High-Tech Products

Hongchang manufactures a wide range of advanced materials, including:

• Rayon-based carbon fiber graphite felt
• PAN-based carbon fiber graphite felt
• Pre-oxidized fiber graphite felt
• High-purity graphite felt
• Quartz crucibles
• Quartz guide tubes
• Flow battery energy storage felt
• Rigid felt and composite felt products

These products are widely used in solar photovoltaics, semiconductors, powder metallurgy, thermal systems, vacuum sintering, aerospace, and new energy storage.

Through strategic cooperation with well-known enterprises across the industry, Hongchang has expanded its market presence both in China and overseas, supported by reliable product quality and strong cost performance.

Contributing to the Dual Carbon Strategy

As new opportunities emerge from industrial transformation and the global shift toward cleaner energy, Hongchang is committed to supporting China’s Dual Carbon strategy.

With advanced technology, growing production capacity, and continued investment in research and development, the company aims to remain a leader in thermal-field insulation materials and flow battery energy storage solutions.

Hongchang’s mission is clear: to advance technology, support industrial progress, and contribute to a more sustainable future.
