Composite Molding Cured Felt (PAN-Based, Viscose-Based)
- Product Description
-
It exhibits excellent integrity and shape retention, strong self-supporting capability, and good thermal stability, with outstanding high‑temperature insulation performance, corrosion resistance, and high purity. It is easy to install and maintain, making it suitable for large‑size flat panels and complex‑shaped components. Its primary applications include high‑temperature heat‑treatment equipment such as single‑crystal silicon pulling furnaces, powder metallurgy industrial furnaces, vacuum sintering furnaces, and deposition furnaces. After undergoing a high‑purity refining process, it can meet semiconductor‑industry standards and is used in various crystal‑growth thermal processing systems.
