Hunan Zhenxiang Materials Technology Co., Ltd. is located in the industrial city of Zhuzhou, and was established under the leadership of Professor Hu Shunqin, a PhD candidate from Hunan University and a professor at Hunan University of Technology. We are a comprehensive technology enterprise dedicated to the research and development, production, sales, and technical services of functional PMI structural core materials. Adhering to the principle of "building a strong country with equipment and winning with materials", we are committed to creating a modern high-tech enterprise that values "quality first, continuous innovation, excellence, and win-win cooperation".

The special functional PMI structural core material has superior performance, with lightweight and high strength, good fatigue resistance, excellent dielectric properties, excellent processing performance and isotropy, high closed cell rate, and good adhesion performance. The compression deformation of ultra-high strength PMI structural core material is less than 1% at a depth of 120m deep sea; The oxygen index of the flame-retardant PMI structural core material of the body has reached a maximum of 32% and has passed the 605 vertical combustion test of the Civil Aviation Administration of China Testing Center; The stealth PMI structure core material has a vertical reflectivity of -15dB and a dielectric constant greater than 2.7 in the X-band; The high-temperature resistant PMI structural core material can work stably for a long time under the conditions of 200 º C and 0.6MPa; The ultra-low temperature PMI structural core material does not become brittle or shrink at -200 º C, and has good mechanical properties; High performance PMI structural core material; High cost-effective PMI structural core materials, etc.

The company also has fiber reinforced monomer nylon, deep-sea buoyancy materials, controllable polyurea resin, carbon foam, ultra-high molecular weight polymethyl methacrylate, epoxy matching layer, aerogel and other new materials.

The company's products have been widely used in aerospace, shipbuilding, rail transportation, automobiles, sports equipment, medical, wind power, communication and other fields.

The global sales volume of PMI foam cores for the aerospace sector reached 173 million US dollars in 2024. Driven by the sustained demand for lightweight solutions in aerospace, wind power, unmanned aerial vehicles (UAVs) and other fields, this niche market is projected to hit 568 million US dollars by 2031, with a Compound Annual Growth Rate (CAGR) of 18.5% from 2025 to 2031.

Aerospace is the most core downstream application field of PMI foam cores, accounting for approximately 80% of the global PMI foam consumption. The growing demand for lightweight applications in key components such as aircraft fuselages, wings, propellers and wind turbine blades serves as the core driver for the rapid growth of this niche market.
