WebApr 1, 2024 · Visco foam belongs to viscoelastic foams, which result from the effects occurring in its internal structures. Being viscoelastic means being both sticky and elastic at the same time. However, in reality, there are no substances that are sticky and fully elastic at the same time. This means that visco foam loses elasticity with increasing viscosity.
