Calcium Fluoride

Thickness [2.5D thick flat plate product series]: 1~90 mm Width [2.5D thick flat plate product series]: 100~1300 mm Honeycomb cell edge length [Honeycomb structure series]: Customizable

3D woven preforms are anisotropic and readily support near-net-shape weaving of complex structures with high design flexibility. Warp and weft contents are tailored to directional mechanical requirements. Fabric rigidity can be adjusted for subsequent manufacturing and service conditions of different composites. These 3D preforms can be customized to customer requirements.

Thickness [Three-dimensional woven plate series]: 1~40 mm Width [Three-dimensional woven plate series]: 10~200 mm Length [Three-dimensional woven plate series]: 5 m

3D integral braiding produces variable or irregular cross sections. Changing carrier-array shape, yarn fineness on each carrier, and carrier motion directly forms 3D preforms to a part's shape and dimensions, preserving overall structural performance. The 3D products are formed integrally in one operation, with a nonlayered structure, greater interlayer strength, and improved overall mechanical properties.

Thickness [Needling and stitching series]: 1~200 mm Bulk density [Needling and stitching series]: 0.1~0.9 g/cm³

Automatic stitching integrally forms different laminated fabrics and preforms.

Areal density [Needled web series]: 50~400 g/㎡ Width [Needled web series]: 1000 mm Length [Needled web series]: ≤60 m

Quartz chopped fibers are opened, carded, and needle-punched.

Total metal impurity content [F-HIR material overview (not separated by grade)]: ＜10 Hydroxyl Content [F-HIR material overview (not separated by grade)]: ＜1 Temperature rise [F-HIR material overview (not separated by grade); 10000W, 150S]: ＜5

F-HIR is a highly preferred material for high-power lasers, DUV optical systems, lighting, measurement equipment, and KrF/ArF photomask substrates.
