PET (Polyethylene Terephthalate) is a remarkable and high-performance crystalline polymer material. It stands out due to its exceptional optical clarity, superior impact resistance, and robust high barrier properties. Additionally, PET is known for its excellent environmental performance. This versatile material finds extensive applications in various manufacturing processes such as injection molding, sheet extrusion, injection-stretch-blow molding, and spinning, making it a top choice in the industry.
Throughout the production journey of PET products, some challenges have been identified, which may affect product quality. Common issues include unwanted product yellowing or whitening, troublesome mold sticking, reduced toughness, unsightly flow marks, and imperfections such as burrs and scratches. Addressing these challenges is crucial for maintaining the high-quality standards expected from PET materials.
