XINGHUI MATERIALS can provide matching rigid felts and flexible felts as insulating materials in various high-temperature vacuum heat treatment fields, including photovoltaics, semiconductors, and high-temperature metallurgy. Currently, our insulating product series holds a market share of over 25% in the high-temperature vacuum industry and over 60% in the photovoltaic polycrystalline thermal field.
Our special manufacturing process ensures that the insulating rigid and flexible felts have extremely uniform thickness and density distribution, guaranteeing consistent high insulation performance. They also feature high oxidation resistance, slow fiber powdering rate, and long service life.
Standard carbon fiber flat rigid felt is produced by mixing and pressing of Pan-based carbon fiber material and binder, followed by high temperature treatment at temperature up to max 2400℃. In the final production step the rigid felt is machined to the desired dimensions.
Rigid felt is a rigid insulation material with low thermal conductivity based on carbon fibers. It shows its best performance in temperatures beyond 800℃ in inert gas or vacuum furnaces.
