Grand-Hope New Materials — The Pioneer in Domestic Substitution of Rigid Felt.
Short-fiber rigid felt insulation material is a high-performance thermal insulation material primarily made from short carbon fibers (including trimmings) through processes such as dry forming and vacuum filtration. It offers core advantages including high-temperature resistance (up to 2000°C+), low thermal conductivity, strong thermal field stability, low dust generation, and long service life. It is a key thermal field consumable in high-end, high-temperature applications such as semiconductors (silicon carbide substrate crystal growth), new energy photovoltaics (high-temperature furnaces), and powder metallurgy. This field was long monopolized by European and American manufacturers, with a domestic localization rate of less than 20%.
Grand-Hope New Materials is a core frontrunner in domestic substitution within this field:
First, it has achieved breakthroughs through cross-domain technological integration. By collaborating with European carbon fiber R&D teams and domestic research institutions, it has mastered a full set of core technologies, holds 25 patents (including international invention patents), and its core products—silicon carbide rigid felt and second-generation thermal field materials—match top international standards in performance while costing 15%-20% less.
Second, it was a market pioneer in achieving industrialization validation. It is one of the few domestic companies to have passed certification and achieved batch supply for leading domestic silicon carbide substrate customers, breaking the dominance of European and American players.
Third, production capacity and capital backing solidify its leading position. Its subsidiary in Henan serves as the production base, with a planned Phase II investment of 150 million RMB to achieve an annual output of 500 tons. Supported by two rounds of financing from investors like Yida Capital and Yonghua Investment, it continuously provides key material support for the autonomy and controllability of the semiconductor and photovoltaic industry chains, establishing itself as a benchmark enterprise in the domestic substitution of short-fiber rigid felt insulation materials.
