At Astoj, durability is quantified through rigorous mechanical testing. Our latest tensile strength analysis focused on high-tenacity polyester filaments used in heavy-duty lifting slings and safety harnesses.
Using our computerized universal testing machine (UTM), we measured the “Break Force” and “Elongation at Break.” The results confirmed that our proprietary heat-setting process increases the molecular alignment of the polymer chains, resulting in a 15% higher load capacity compared to standard industrial grades.
Key Metrics Tracked:
- Elastic Modulus: Resistance to elastic deformation.
- Yield Point: The stress level at which permanent deformation begins.
- Ultimate Tensile Strength (UTS): The maximum stress the fabric withstands before failure.
