耐火纤维具有一般纤维的特性，如柔软、有弹性、有一定的抗拉强度，可以进一步把它加工成各种纸、线、绳、带、毯和毡等制品；又具有一般纤维所没有的耐高温、耐腐蚀性能。作为耐火隔热材料，已被广泛应用于冶金、化工、机械、建材、造船、航空、航天等工业部门。
Refractory fiber has the characteristics of general fiber, such as softness, elasticity and certain tensile strength. It can be further processed into various products such as paper, thread, rope, belt, blanket and felt, and has the high temperature and corrosion resistance that general fiber does not have. As refractory and heat insulation materials, it has been widely used in metallurgy, chemical industry, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
