Campus Football Primary and Secondary School Students No. 5

• Safe, soft-elastic material: Made of food-grade flexible PVC (0.8mm thick), with a Shore A hardness of only 65A, it reduces impact force by 30% compared to traditional soccer balls. Certified to the national toy safety standard GB6675-2014, it ensures youth sports are free of ankle injuries.
• Triple-layer explosion-proof construction: A butyl rubber liner (pressure-maintaining for 10 days) + a high-density nylon yarn wrapping layer (200D/3-strand) + a cushioning foam interlayer. Tested to withstand 5,000 drops from 1.5 meters without breaking, the inflated diameter is 21.5 0.5cm (standard size 5 ball) and weighs 390-410g (8% lighter than an adult ball). Anti-slip and wear-resistant design: The outer surface features a diamond-shaped embossed treatment (coefficient of friction 0.58), improving ball control stability on wet surfaces by 25%. The seams are double-stitched with 8-strand nylon thread (2.5mm stitch length), with a wear resistance of 3,000 times (ASTM D3884 standard), making it suitable for training on playgrounds, parks, and other surfaces.
• Professional training configuration: The surface is clearly printed with the "Elementary and Middle School Training Ball" logo and size markings, and the orange dynamic stripes enhance visual tracking (increasing nighttime visibility by 40%). - It complies with the requirements of the campus football curriculum and has been tested and certified by the China Educational Equipment Research Institute.
• Fast Rebound System: Optimized liner pressure parameters (0.6-0.8 bar) combined with a high-elastic yarn wrapping layer increase shot rebound response by 15% and shorten the ball's stopping distance to 8-12cm, helping young players develop proper ball contact muscle memory and improving training efficiency by 20%.
