Research for Instrument panel Processing technique of TPO micro cellular foam application |
| 초록 |
Thermoplastic foams are materials that comprise a cellular core structure created by the expansion of a blowing agent, which is usually a volatile gas or liquid. This internal core structure enables the foamed plastics to be economically used in insulating, packaging, and structural industries. Thermoplastic olefins(TPO) are currently evaluated as a potential replacement of PVC/ABS blends in automotive interior such as Instrument Panel(IP) skins. Some of the advantages of TPO over PVC/ABS skins are improved UV and heat aging, reduced fogging due to absence of plasticizer exudation, and recyclability. The nucleation and volume expansion behaviors of ethylene-octene copolymer were investigated at various MFR of polypropylene types while fixing the nitrogen content to be 0.5 wt.%. The effects of changing polypropylene type on the cell density, final expansion ratio, and processing window are discussed. |
