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 .

• non-heat-treated materials 12% (+/-1%)
• heat-treated fabrics (ta), depending on the treatment regime, from 1% to 3%.

• insulation and protection applications, such as sealing, packaging, protective screens.
• drop cloth for welding and fire curtains.
• reinforcement for acid resistant composites.
• filtration of molten metal and furnace exhaust, etc.
• exhaust systems for automobiles.
