Li Ningyun damping principle

Viscoelastic body with rubber property is added into the formula of Li Ningyun damping technology, and the wrinkle of foam cavity wall that constitutes the basic frame of midsole is very beneficial to the rapid recovery of elasticity after the midsole is compressed, thus generating higher rebound energy, just like a spring. At the same time, the addition of benzene ring in the rubber molecular structure enhances the toughness of the foam cavity wall from the microscopic point of view, and greatly improves the resilience, durability and shock absorption of the "Li Ningyun" midsole material. In addition to excellent performance in cushioning, Li Ningyun series products are also soft and light. At present, Li Ningyun's unique modified EVA foaming formula technology has obtained the invention patent certification of China ZL20110306439.3.
