IMPACT ABSORBING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an impact absorbing material which has excellent flexibility and excellent impact absorption even when its thickness is thin, and can follow a minute clearance.SOLUTION: An impact absorbing material is composed of a foam having an average cell diameter of 10 to 65μm and a density of 0.01 to 0.20 g/cm. The foam is formed of a resin composition comprising a mixture of a thermoplastic elastomer and a thermoplastic polymer other than the thermoplastic elastomer, and has an impact absorption defined by formula (1) of 40 to 90% and a thickness of 0.10 to 0.5 mm. One or both surfaces of the foam have an adhesive layer having a thickness of 2 to 100μm. Impact absorption (%)=(F0-F1)/F0×100 (1)
