Seat Belt Nylon Webbing

Overview

Seat Belt Nylon Webbing (SKU: NW-SB-003) is a high-tenacity woven strap engineered for critical restraint applications that demand exceptional strength, controlled elongation, and long-term durability. Manufactured from premium high-tenacity nylon 6,6 multifilament yarns using precision shuttle and needle-loom weaving, the webbing delivers a dense, uniform weave structure with consistent load-bearing performance across its full width. Its balanced combination of energy absorption and dimensional stability makes it suitable for occupant restraint systems and other safety-critical harnessing where predictable mechanical behavior under load is essential.

Key Features & Specifications

• Material and construction: 100% high-tenacity nylon 6,6 multifilament yarn, twill/2x2 satin weave with reinforced selvage edges for fray resistance and smooth retractor feed.
• Tensile / breaking strength: minimum break strength of 8,000 lbs (approximately 35.6 kN) for the 48mm automotive grade; 25mm units rated at approximately 6,000 lbs (26.7 kN). Values scale with width and yarn denier.
• Width and thickness: standard widths of 25mm, 38mm, 46mm, 48mm, and 50mm (approximately 1 to 2 inches); nominal thickness 1.1mm to 1.3mm depending on weave density and specification.
• Weight and elongation: typical areal weight of 55 to 62 g/m for the 48mm grade; controlled elongation of 8% to 12% at 11.1 kN, providing calibrated energy absorption during dynamic loading.
• Abrasion and UV resistance: retains greater than 85% of original tensile strength after 5,000 abrasion cycles; UV-stabilized formulation retains greater than 80% strength after 500 hours of accelerated weathering (QUV) exposure.
• Temperature and chemical tolerance: stable operating range of -40°C to +90°C; resistant to mildew, common solvents, and moderate chemical exposure, with low moisture regain to maintain consistent load performance.

Applications

• Automotive occupant restraint systems: primary seat belt webbing for passenger vehicles, light trucks, and commercial fleets, where controlled elongation manages crash energy while meeting OEM specification tolerances for width, thickness, and break strength.
• Motorsport and racing harnesses: 2-point, 4-point, 5-point, and 6-point competition harness assemblies requiring high break strength, low stretch variance, and consistent color matching for branded team equipment.
• Transportation and cargo safety: shoulder and lap restraints for buses, coaches, agricultural machinery, forklifts, and off-highway vehicles operating in demanding duty cycles and temperature ranges.
• Child restraint and mobility systems: webbing for child safety seats, wheelchair tie-down and occupant restraints (WTORS), and medical transport harnesses where retractor compatibility and edge smoothness are critical.
• Aviation, marine, and industrial restraint: aircraft seat belts, marine safety harnesses, and industrial fall-arrest or positioning components where certified, traceable, high-strength webbing is required.

Customization & Wholesale

WebbingMaker supplies Seat Belt Nylon Webbing on a bulk wholesale and OEM basis with flexible customization to match buyer specifications.

• Minimum order quantity: 500m per color and specification for standard stock widths; 1,000m to 3,000m MOQ for fully custom weaves, dope-dyed colors, or non-standard widths.
• Custom widths: any width from 20mm to 75mm can be produced to order; standard tooling covers 25mm, 38mm, 46mm, 48mm, and 50mm for faster turnaround.
• Color and dyeing: piece-dyed and dope-dyed (solution-dyed) options for superior UV and wash fastness; custom color matching to Pantone or physical swatch, with typical color tolerance within Grade 4 on the gray scale.
• Printing and marking: continuous logo printing, batch/lot marking, meter markings, and heat-transfer or woven-in identification available for brand traceability and regulatory labeling.
• OEM and private label: full OEM production to customer drawings and specifications, including tailored break-strength, elongation curves, weave patterns, and packaging under the buyer's brand.
• Packaging: standard put-ups of 100m or 200m per roll on cardboard or plastic cores, shrink-wrapped and carton-packed; custom spooling, reel lengths, and export cartons available on request.
• Lead time: 7 to 15 days for stock widths and colors; 20 to 35 days for custom specifications and large-volume OEM orders, subject to quantity and finishing requirements.
• Export capabilities: experienced in global bulk shipping via sea and air freight, FOB, CIF, and DDP terms supported, with full export documentation, HS coding, and certificates of origin provided.
