Products classified under HTS 7019.14.00.00
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.
Geotextile Grade Mechanical Glass Mat
Mechanically needled glass fiber mats designed for soil stabilization and drainage in civil engineering geotextiles. HTS 7019.14.00.00 for mechanically bonded mats of glass fibers, valued for high tensile strength and filtration. UV-stabilized without chemical binders.
C-glass Mechanically Bonded Mat for Corrosion Resistance
C-glass (corrosion-resistant) fibers formed into mechanically bonded mats for chemical tanks and pipes in FRP. HTS 7019.14.00.00 includes all glass fiber types in mechanical mats, per fused silica/glass definition. Higher cost but superior to E-glass in harsh environments.
Wind Blade Infusion Mat Mechanical
Large-format mechanically stitched glass mats optimized for vacuum infusion in wind turbine blade manufacturing. HTS 7019.14.00.00 for mechanically bonded glass fiber mats, with biaxial or triaxial layups. Engineered for low resin uptake and high strength.
Marine Hull Repair Mechanical Glass Mat
Flexible mechanically bonded chopped strand mats for on-site FRP boat hull repairs and gelcoat layering. Classified in HTS 7019.14.00.00 as glass fiber mechanically bonded mats. Easy to cut and conform to curved surfaces.
HighLOFT Mechanical Glass Fiber Mat
High-loft needled mats with voluminous structure for thermal/acoustic insulation in HVAC systems. HTS 7019.14.00.00 covers these mechanically bonded glass fiber mats, bulkier than standard chopped strand. Excellent sound absorption properties.
Automotive Panel Reinforcement Mat
Mechanically bonded glass mats for reinforcing thermoplastic panels in car doors and dashboards via compression molding. Under HTS 7019.14.00.00 for glass fiber mats mechanically bonded. Lightweight with good molding flow.
S-Glass Mechanical Bond Mat for Aerospace
High-strength S-glass fibers in mechanically stitched mats for aircraft interior panels and radomes. HTS 7019.14.00.00 for premium glass fiber mechanically bonded mats. Superior modulus to E-glass.
Chopped Strand Mat 450g/m² Mechanical Bond
This 450 grams per square meter chopped strand mat uses mechanical needling to bond E-glass fibers, ideal for hand lay-up in fiberglass reinforced plastics. Classified in HTS 7019.14.00.00 for mechanically bonded mats of glass fibers, excluding yarn or woven products. Commonly used in automotive parts and corrosion-resistant panels.
Stitch-Bonded E-Glass Mat
Stitch-bonded mats secure layers of chopped glass fibers using mechanical stitching with polyester yarn, forming a flexible reinforcement sheet. Under HTS 7019.14.00.00 as mechanically bonded mats thereof, used in wind energy blades and boatbuilding. The stitching provides integrity without resins.
Lightweight 225g Chopped Glass Mat Mechanical
A 225 g/m² mechanically bonded mat of chopped E-glass strands, needled for thin, drapable reinforcement in surfboards and panels. HTS 7019.14.00.00 applies to these glass fiber mats mechanically bonded, excluding heavier industrial grades. Ideal for resin infusion processes.
Multiaxial Glass Fiber Mat Mechanically Bonded
Multiaxial mats layer glass fibers in multiple directions (0°, 45°, 90°), mechanically stitched for isotropic strength in aerospace composites. Falls under HTS 7019.14.00.00 for mechanically bonded glass fiber mats. Provides superior load distribution without weaving.
Roofing Reinforcement Mechanical Glass Mat
Heavy-duty mechanically bonded glass mats used as base sheets in asphalt shingle reinforcement and built-up roofing. Classified HTS 7019.14.00.00 as glass fiber mechanically bonded mats, providing tear resistance. Typically 100-200 g/m² for durability.
Battery Separator Glass Mat Mechanical Bond
Ultra-thin mechanically bonded glass fiber mats serving as separators in lead-acid batteries, allowing electrolyte flow. Under HTS 7019.14.00.00 for glass fiber mats mechanically bonded, critical for electrical insulation. High purity and absorptive properties.
