Longhua Technology, with its core focus on design and manufacturing technologies in the polymer composite materials sector, adheres to the concept of "one core, diversified development." It has built a product matrix covering resin-based structural-functional integrated composite materials, functional rubber materials, structural-functional integrated foam materials, and special modified resins, serving multiple key fields such as military security, rail transportation, and environmental energy. In the future, the group will continue to improve its technology system and create a diversified and collaborative polymer composite materials industrial ecosystem.
Zhaoheng Technology: Breakthrough in PMI Foam Technology - Wave Absorbing Materials
Hunan Zhaoheng Materials Technology Co., Ltd., as a "technology service provider of functional-structural integrated materials based on high-performance PMI foam," produces PMI foam series products that are essential supporting materials for various aircraft, drones, and other flying vehicles (fusels, wings, propellers, etc.) made of carbon fiber composite materials. These products are also widely used in maglev trains, ships, vehicles, radar communications, audio equipment, medical equipment, sports and leisure equipment, and many other fields. In July 2025, Zhaoheng Technology's project, "Research and Industrialization of Polymethacrylimide Absorbing Foam (EPMI) Based on Carbon-Based Absorbers," passed the scientific and technological achievement evaluation and was rated as "internationally advanced." This breakthrough marks a leap from "following" to "keeping pace" in the field of microwave absorbing functional materials in my country, providing key technological support for defense, communications, and other fields.
Siyunuo New Materials: PVC Structural Foam - Quality and Service Guaranteed
Luoyang Siyunuo New Materials Technology Co., Ltd. possesses PVC structural foam with completely independent intellectual property rights and passed DNV certification in one go in 2017. The product features high closed-cell rate, low resin absorption, and excellent mechanical properties, temperature resistance, and chemical corrosion resistance. It can be composited with reinforcing materials such as glass fiber, carbon fiber, and aramid fiber through a "sandwich structure" (core material + upper and lower skins), supporting mainstream processes such as vacuum infusion, hand lay-up, and autoclave processing. It is widely used in wind turbine blades, marine engineering, drones, special vehicles, and other fields. The company has built a nearly 100-acre production base in the Mengjin Chemical Industrial Park of Luoyang, equipped with over 30,000 square meters of production workshops and warehouses, and possesses more than 150 sets of advanced processing equipment. It meets customers' personalized and differentiated customization needs and is a major supplier to large state-owned enterprises and listed companies such as Sinoma Blades, Chongqing Heavy Machinery Group, and Mingyang Smart Energy.
