High-purity rubber-based carbon fiber felt
product Description
Impurity content is one of the key concerns in the thermal field environment of the third-generation semiconductor crystal growth furnace. In order to effectively ensure the normal growth and development of SIC crystals, the production of high-purity rubber-based carbon fiber insulation felts not only takes into account thermal insulation properties, but also can stably control the internal ash content below 20PPM, and the annual output can reach 100T/A.
