종래의 자동차용이나 인테리어용 제품에 사용되는 진공성형용 자동차 인테리어 내장재는 구조적으로 보았을 때 표면스킨층을 형성하는 레이어(PVC, TPO)와 이면층을 형성하는 폼층으로 구성되어 있다.The interior automobile interior material for vacuum molding used in a conventional automobile interior or interior product is structurally composed of a layer (PVC, TPO) forming a surface skin layer and a foam layer forming a backside layer.

일반적으로 폼층에는 전자선 가교 폼이 사용되어지며 이때 쓰이는 재료는 열가소성 올레핀이나, 폴리프로필렌이 사용되고 있다. 상기와 같은 합성수지로 형성되는 폼은 자동차의 운전석 앞 부분을 차지하는 인스트루먼트 패널, 그리고 도어의 업퍼(UPPER)부위와 센터(CENTER) 부위에 주로 사용되어 진다. 합성수지 폼을 성형하기 위해 진공성형기에 장착하여 성형을 하게 되는데 이때 열이 가해지고 금형으로 압착, 냉각 공정을 통해서 성형품이 제작된다. In general, an electron beam crosslinked foam is used for the foam layer, and a thermoplastic olefin or polypropylene is used as the material. The foam formed of synthetic resin as described above is mainly used in the instrument panel occupying the front portion of the driver's seat of the automobile, and in the UPPER portion and the CENTER portion of the door. In order to form a synthetic resin foam, it is mounted on a vacuum molding machine, where heat is applied, and a molded product is manufactured through a compression and cooling process with a mold.
