High Silica Yarns



High silica yarns are made of continuous filaments that contains 94% ~ 98% SiO2. Its service temperature can withstand up to 1400°C ( 2552°F ) for a short time, and continuously work at 1000°C ( 1832°F ) environment. Due to sintering and pre-shrinking treatment, our high silica yarns perform excellent thermal insulation at refractory grade while limiting its shrinkage or loss on ignition at maximum.

High Silica Yarns

High silica yarns are generally used for brading sleevings or other forms of textile weaving, sewing thread, lamp-wicks, atomizer of electronic cigarettes, winding or wrapping heating wire or other heating components, high temperature gaskets, etc...
