1. Tensile Strength

This heavy duty elastic band achieves a safe tensile strength of over 120% under standard testing conditions, with a breaking tensile strength of approximately 160%, maintaining structural integrity even in high-frequency tensile environments. Through multiple cyclic tensile tests, its tensile force decay rate is less than 10%, ensuring stable stress performance over long-term use, suitable for applications requiring consistent tensile force.

2. Rebound Stability

In 1000 consecutive tensile rebound tests, the elastic recovery rate remains above 92%, indicating that the material is not prone to permanent deformation after repeated stress. The rebound speed is controlled within a reasonable range, avoiding both excessively fast rebound causing operational discomfort and excessively slow rebound affecting efficiency, making the overall use process more stable and controllable.

3. Line Width Accuracy

The product line width is controlled within ±0.3mm of the nominal size error. Taking the 1/2-inch specification as an example, the actual width is consistently around 12.7mm. A stable line width helps to distribute stress evenly, reducing localized stress concentration and thus lowering the probability of edge curling or tearing, improving overall durability.

4. Fatigue Resistance

After 5000 tensile fatigue tests under laboratory conditions, the elastic band still retains more than 85% of its original elasticity, with no obvious fiber breakage or structural loosening. This data indicates that its internal fiber arrangement is dense, suitable for long-term repeated use, and can effectively reduce replacement frequency.

5. Roll Specifications

This heavy duty elastic band is configured with 100 Yards per roll as standard, reducing the number of roll changes during continuous cutting. The overall roll weight is controlled within a reasonable range, facilitating manual handling and equipment unloading, while ensuring uniform winding tension and avoiding loosening or skipped threads during use.

1. Garment Accessories

In garment production, this heavy-duty elastic band is commonly used in structural areas requiring stable contraction. Its stretch range matches the range of human movement, maintaining its original tightness after repeated wear and removal, reducing garment deformation due to elastic fatigue, and improving the overall durability of the garment.

2. Industrial Bundling

In light industrial bundling scenarios, this elastic band can be used to temporarily secure components or materials. Its controllable stretch performance makes single-bundle lengths easier to predict, reducing repeated adjustment time, while maintaining a stable stress state during transportation or handling.

3. Packaging Fixing

In the packaging field, this heavy-duty elastic band provides continuous tension without damaging the outer packaging. Its elastic cushioning helps absorb changes in external force within a certain range, reducing the risk of packaging loosening during stacking or movement.

4. Handcrafting

In handcrafting, this elastic band is widely used due to its consistent dimensions and smooth cutting. Users can precisely control the length according to their needs, reducing material waste while maintaining a neat appearance in the finished product.

5. Equipment Auxiliary

In the auxiliary structures of some equipment or tools, this elastic band can be used as a non-load-bearing elastic connector. Its stable rebound characteristics help maintain the alignment of components and prevent insufficient elasticity from affecting the overall coordination of the equipment.

Q: What is the main difference between this type of elastic band and ordinary elastic band?

A: Heavy-duty elastic bands have higher tensile strength, resilience, and fatigue resistance than ordinary elastic bands, making them more suitable for scenarios requiring repeated stretching and long-term use.

Q: Can it be used under tension for extended periods?

A: As long as the recommended stretching ratio is not exceeded, it can be used under tension for a relatively long time. Its elastic decay rate has been tested and controlled at a low level, making it less prone to rapid failure.

Q: Will the edges of the heavy-duty elastic band easily fray after cutting?

A: The internal fiber structure of this elastic band is dense, and the edges are stable after normal cutting, with little tendency for significant fraying. It is suitable for manual or batch cutting.

Q: Are there performance differences between different width specifications?

A: Different widths mainly affect the stress distribution per unit length. The core elasticity and fatigue resistance remain consistent. Choose the appropriate specification according to actual needs.

Q: What precautions should be taken when storing it?

A: It is recommended to store it flat or upright in a dry, room-temperature environment, avoiding prolonged pressure or direct sunlight to maintain the material's original elasticity.
