WebAdvanced Plastiform, Inc is a leader in plastic manufacturing including heavy gauge thermoforming, twin sheet forming, vacuum forming & injection molding. WebJun 9, 2024 · A high P sat not only creates a high CO 2 concentration gradient inside and outside the foam but also significantly decreases the cell wall thickness, which leads to a high CO 2 diffusion rate out of the foam and results in more severe foam shrinkage. Therefore, foaming TPU at 13.78 MPa resulted in the highest shrinkage ratio.
