Products classified under HTS 7019.64.90.30
Silica Filament Plain Weave Fabric for Aerospace Insulation
This is a closed woven, plain weave fabric made from silica filaments with over 93% silica content, coated for enhanced durability and heat resistance. It falls under HTS 7019.64.90.30 as a mechanically bonded, colored, laminated silica filament fabric used primarily for thermal insulation in aircraft engines and space vehicles. The high silica purity provides exceptional performance in extreme high-temperature environments.
High-Purity Silica Fabric for Industrial Furnace Curtains
A specialized plain weave fabric from >93% silica filaments, mechanically bonded and laminated with colored heat-resistant coating for furnace applications. Classified in HTS 7019.64.90.30 due to its closed weave structure, high silica purity, and protective lamination for extreme thermal exposure. Commonly used as protective curtains in high-temperature industrial furnaces.
Colored Laminated Silica Cloth for Kiln Seals
This coated, plain weave silica filament fabric (>93% silica) is mechanically bonded and colored for use in high-temperature kiln door seals and expansion joints. It qualifies for HTS 7019.64.90.30 as a closed woven, laminated fabric designed for thermal barrier applications in ceramics and glass manufacturing. The lamination provides flexibility and sealing properties under extreme heat.
Silica Filament Thermal Barrier Fabric for Rocket Motor Insulation
