In order to replace PVC with TPO as I/P skin layer of invisible PAB, the elongation behavior, vacuum thermoforming, thermal, light resistance and low temperature PAB deployment of TPO were investigated. With the elongation properties; 50cN ↑ melt strength, 300mm/s ↑ breaking speed, 200s ↑ breaking time, TPO was vacuum-formed well like PVC. The thermal and light resistances of TPO were superior to PVC. In terms of low temperature airbag test, PVC was fractured with the brittle behavior during the deployment. TPO, however, showed the ductile fracture. And also when TPO was used for PAB cover, the elongation ratio of TPO was also important criterion for the normal break without any interference to I/P part, outside of PAB. The 300∼500% elongation ratio was most preferable.
