20mm Polyester Webbing

Our 20cm Non-Elastic Polyester Webbing is engineered for strength and durability, making it the perfect solution for applications requiring a sturdy, non-stretch strap. Crafted from premium polyester fibers, this webbing offers excellent resistance to abrasion, UV exposure, and moisture, ensuring long-lasting performance even in harsh environments. The 20cm width provides ample surface area for secure fastening, while the non-elastic property guarantees consistent tension without deformation under load. Ideal for industrial use, safety Harnesses, outdoor gear, and more, this polyester webbing combines reliability with versatility to meet diverse application needs.

20mm polyester webbing is a flat, woven strap manufactured from polyethylene terephthalate (PET) fibers using high-density weaving techniques. Key characteristics and data include:

1. UV Resistance

• The benzene ring structure in polyester absorbs over 98% of UVA/UVB rays. Tests show no embrittlement or fading after 8 hours of exposure under UV Index 11 (equivalent to 3 years of outdoor use).

• Example: Profabrics’ 20mm traditional weave polyester webbing retains 92% of its tensile strength after 3 years of outdoor use.

2. Strength-to-Weight Ratio

• Achieves a breaking strength of 28kN (≈2,850 kgf) while weighing only 48.5 g/m. Advanced weaving (e.g., SLACKTIVITY’s halfMarathon series) reduces weight by 25% without compromising strength.

3. Weather and Chemical Resistance

• Operates in temperatures ranging from -40°C to 80°C with <0.4% water absorption (vs. 4–5% for nylon). After 30 days of seawater immersion, salt residue measures just 0.02 g/cm².

• Example: Sailrite’s gray polyester webbing passes 96-hour salt spray tests (ASTM B117), making it marine-grade.

4. Abrasion and Tear Resistance

• Withstands 100,000 Martindale cycles without fraying. Tent & Awning Clinic’s “Plain Weave” webbing sustains 200 kg tension for 72 hours in tent anchor tests.

II. Applications and Technical Adaptations

1. Outdoor Gear

• Backpacks and Climbing Straps: 20mm width balances load support and comfort. OSPREY’s shoulder straps deform only 3% under 50 kg loads.

• Tent and Awning Fixation: UV resistance extends seam lifespan to 8 years (vs. 3 years for nylon).

• Pet Accessories: Gameness’s 20mm dog leashes withstand 150 kg tension in stretch tests.

2. Industrial and Safety Uses

• Safety Harnesses: Exceeds EN 354’s 22kN minimum requirement by 20–30%.

• Medical Restraints: Victory Built’s antimicrobial-coated webbing inhibits 92% of Staphylococcus aureus.

3. Fashion and Home

• Apparel Trim: 20mm striped webbing (e.g., model 360009WB) achieves ISO 105-B02 colorfastness ratings of 4–5 after 50 washes.

• Furniture Reinforcement: Sailrite’s webbing resists 80 kg tension for 10 years in sofa edge tests.

III. Professional Maintenance and Longevity

1. Cleaning and Stain Removal

• Mechanical Stains: Use bio-enzymatic cleaners (pH 6.8–7.2) at 30°C for 20 minutes. Chlorine bleach degrades polyester by 15–20%.

• Oil Stains: Apply cornstarch to absorb grease, then brush off after 2 hours (residual oil <5%).

2. Softening Treatments (Optional)

• Heat Treatment: Immerse in 80°C water for 5 minutes to realign molecular chains, improving flexibility by 30%. Avoid temperatures >100°C (melting point).

• Vinegar Softening: Add 1 cup white vinegar to wash cycles to break down surface hardness (effects last 10–15 washes).

3. Storage and Damage Prevention

• Humidity Control: Store at 45–55% RH. At 70% RH, moisture absorption reaches 1.2% (mold growth threshold: 1.5%).

• UV Protection: Use opaque packaging for long-term storage. 100 hours of UV exposure reduces strength by 8–10%.

• Folding/Hanging: Avoid sharp bends (radius <5 cm). Use S-hooks to minimize stress concentration.

4. Inspection and Replacement

• Visual Checks: Inspect biannually for fraying, discoloration, or cracks >0.5 mm.

• Tensile Testing: Use a spring scale to verify no breakage at 15% elongation (industry standard: 20% allowance).
