The molecular system of RZLABs is composed of soft segments (flexible chains) and hard segments (functional groups), connected non-covalently via secondary bonds (such as hydrogen bonds, hydrazone bonds, and disulfide bonds). These secondary bonds will absorb more than 90% impact energy by separate and recover in milliseconds.
Under normal conditions, the system is dominated by viscoelasticity:
• The storage modulus (E') is low, ensuring the material is soft and skin-adherent.
• The loss factor (tan δ) is moderate, endowing it with a wide temperature range.
