ABSTRACT:
An air bag is made of thermoplastic urethane resin. The resin has a hardness (Shore scale A) of 88 to 92 measured by JIS K-7311; a tensile strength of 400 kg/cm.sup.2 or more measured by JIS K-7311; a breaking elongation of 400% or more measured by JIS K-7311; a 100% modulus of 70 kg/cm.sup.2 or more measured by JIS K-7311; a 300% modulus of 150 kg/cm.sup.2 or more measured by JIS k-7311; a tearing strength of 75 kg/cm or more measured by JIS K-7311; a pour point of 180.degree. C. to 188.degree. C. measured by Flow Tester; and a melting viscosity of 2.5.times.10.sup.5 Ps/190.degree. C. to 45.times.10.sup.5 Ps/190.degree. C. measured by Flow Tester.
