• PET Foam Overview

  Polyethylene terephthalate (PET) is a polycondensation reaction product of ethylene glycol and terephthalic acid and has a relatively high melting point. As a thermoplastic engineering material, PET has good mechanical properties, electrical insulation, chemical resistance, creep resistance, fatigue resistance and other characteristics, and is widely used in clothing chemical fiber, packaging and transportation and other fields.

• Preliminary Study on the Production Technology of PET Foam

  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

• PET Drying-Free Reactive Extrusion Supercritical Carbon Dioxide Foaming Line

  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.
