    According to the different density, PET foam can be divided into low-density PET foam products and high-density PET foam products. Generally, foam with a density below 100kg/m³ can be considered low-density foam. The current minimum density can be around 60kg/m³, and the density of high-density foam

    In the foaming process, especially under the high shear rate of the extrusion process, as the bubbles grow, the surface tension and melt strength of the PET are insufficient, and the bubble walls become thinner, which easily leads to the rupture of the cells. Therefore, improving the melt strength to prevent cell rupture is a prerequisite for PET foam molding.

    Advantages of PET Foam MaterialPET foam has good dimensional stability, good sound insulation, and heat insulation properties. Its short-term maximum working temperature can reach 200 ℃, and it can be used for a long time at a high temperature of 120 ℃, which is much higher than polyethylene (PE), p
