Abstract

본 발명은 밀도가 낮고 기포 크기가 작은 열가소성 발포 시트를 형성하기 위한 동시 열성형방법을 제공하는 것이다. 이 시트는 크기의 조절 및 시트로부터 열성형된 생성물의 작용성을 개선시킨 게이지가 더욱 얇은 폴리스티렌 기포의 다중 웨브로 형성된다. 동시 열성형된 생성물은 연성 및 표면 특성이 개질된다.The present invention provides a simultaneous thermoforming method for forming a thermoplastic foam sheet having a low density and a small bubble size. The sheet is formed of multiple webs of thinner polystyrene bubbles with gauges that improve the control of size and the functionality of the thermoformed product from the sheet. Co- thermoformed products have modified ductility and surface properties.
