Polyethylene Terephthalate, or PET, is a premium crystalline polymer renowned for its outstanding optical clarity, exceptional impact resistance, and superior barrier properties. This environmentally-friendly material is versatile, finding extensive use in injection molding, sheet extrusion, injection-stretch-blow molding, and spinning among other applications.
Throughout the production of PET products, various challenges have been noted, such as product yellowing or whitening, mold sticking, poor toughness, flow marks, burrs, and scratches.
