During a Q3 2025 site inspection of a 50,000-pair shipment, the EVA foam clogs exhibited Shore A hardness of 55 ±2 (ASTM D2240), tensile strength of 2.8 MPa (ASTM D412), and a density of 0.15 g/cm³. The cross-sectional porosity was uniform at 25 cells/cm², confirming consistent air trapping for cushioning. Abrasion loss was <0.1 g/cm² per ISO 4649. No delamination or flash defects were observed in a random 200-pair sample.The product meets ISO 9001:2015 quality management standards and has passed ASTM F2413-18 for slip resistance (coefficient of friction >0.5 on wet tile). The manufacturing process is certified under ISO 14001:2015 for environmental management. Technical data sheets cite a compression set of <15% per ASTM D395 and a tear strength of 12 N/mm per ASTM D624. Compliance with REACH and RoHS is documented.
Q: What is the minimum order quantity (MOQ) for custom colors? A: MOQ is 1,000 pairs per color, with a lead time of 20 days for first orders and 12 days for repeat. Q: Can the material be adjusted for lower hardness (e.g., Shore A 45)? A: Yes, via formulation modification; minimum batch of 5,000 pairs and additional 5-day R&D lead time. Q: Are ASTM test reports provided per shipment? A: Yes, a certificate of compliance with batch-specific test data is included for each container.
