以聚丙烯腈基炭毡为原材料,经特殊高温工艺石漠化处理,具有质轻,炭含量高、耐烧蚀、抗腐蚀、纯度高,高温挥发小、导热系数小、高温下性能稳定,是高温真空炉(85,90,95单晶炉)的首选保温材料。
Graphite felt is made from PAN-based carbon vinyl with special high temperature graphitization process treatments. The product has light weight, high carbon content, ablatives resistance, anticorrosion, high purity, low thermal conductivity, stable performance and light volatilization in high temperature, so the product is preferred to be the insulator of high temperature vacuum furnace.
