Silica cloth

TOMBO™ No. 8250

Silica Textile

This is a silica cloth developed for severe conditions in high temperature ranges for which glass cloth is not compatible. Due to the high purity of the SiO2 fiber, there is little deterioration in the silica cloth even when used at high temperatures, making it particularly suitable for applications requiring heat resistance, acid resistance, and electrical insulation.
