Valmiera is the leading manufacturer of High Silica fabric in the world.
High silica fabric is produced by leaching special E-Glass fabric with soft acid. Our fabric has 96% silica and also Aluminum Oxide (Al?O?) - 3.5 +/- 0.5% to enhance temperature resistance and make the fabric very soft (special properties). High Silica fabrics can be used over a long period without losing the properties and without melting & vaporising at temperatures of up to 1000ºC.
High Silica fabric is available with/without vermiculite coating, heat- treated and mass per unit area 180 to 1100 g/m2 .
