E-Glass Mechanically Bonded Mat
E-Glass mechanically bonded mats consist of chopped glass fibers bonded together without chemical resins, used primarily as reinforcement in composite materials. They fall under HTS 7019.14.00.00 as mats of glass fibers that are mechanically bonded, distinguishing them from chemically bonded or woven fabrics. These mats are lightweight and provide strength in applications like boat hulls and wind turbine blades.
Needle-Punched Glass Fiber Mat
Needle-punched mats are produced by mechanically interlocking chopped glass fibers through repeated needle punching, creating a stable non-woven structure. HTS 7019.14.00.00 covers these mechanically bonded mats of glass fibers, used in roofing felts and geotextiles. They differ from stitch-bonded or resin-bound variants.
