Men's Heavy Duty PU Rubber Work Boots With Composite Toe Waterproof Insulated ASTM F2413-18 Acid & Oil Resistant Anti Slip On Ice

Sole material: PolyurethaneOuter material: Polyurethane (PU)Closure type: Pull-OnWater resistance level: WaterproofComposite Safety Toe: Load the compression force at a speed of 222.4 N/s to 11121 N after compression, meet ASTM F2413-18 standards.Anti-puncture: Puncture-proof midsole fabric in compliance with CSA-Z195, can not be pierced when the puncture force is loaded at 1200N.Cold protection: The combination of polyurethane (PU) with jacquard cloth, SBR, and a breathable waterproof membrane is highly effective for cold protection. Tested at -40°C for half an hour, the temperature drop is limited to within 10°C. PU's flexibility and crack resistance at low temperatures, like -40°C, make it advantageous in this combination.Waterproof Insulated Material: The PU material combined with the composite waterproof membrane on the inner material ensures that the dynamic waterproof twists and turns 50,000 times without leaking.Anti-slip On Ice: During four tests on an ice surface at -7°C, a force of 500N was applied to the outsole. The measured friction resistance of the outsole met or exceeded the standard of SATRA TM144, which requires a minimum friction resistance of 0.3, meets anti-slip standards on ice. outstanding for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
