Ceramic Fiber Blanket
SDTECH Ceramic Fiber Blanket is a refractory insulation material for extreme high-temperature applications, manufactured using an advanced spinning process. Its long fiber length and high tensile strength give it excellent shape retention, while remaining lightweight and highly durable. The operating temperature range is 950°C (1,700°F) to 1,450°C (2,500°F).
