Latest Patents

Tsunaki Kitahara holds a patent for a foamed sheet that features a thickness ranging from 30 to 500 μm. This foamed sheet includes a foam with a density between 0.2 to 0.7 g/cm³ and an average cell diameter of 10 to 150 μm. Notably, the foam exhibits a peak top of loss tangent (tan δ) occurring within a temperature range of -30°C to 30°C. The loss tangent is defined as the ratio of a loss modulus to a storage modulus, determined at an angular frequency of 1 rad/s during dynamic viscoelastic measurement of the foam. The foam is designed to have a maximum loss tangent of 0.2 or more within the specified temperature range.
