PCTG is a highly transparent copolyester material that is widely utilized in consumer products due to its superior physical properties and the absence of bisphenol A, particularly in cosmetic packaging and plastic drink cups. Its excellent flame-retardant characteristics make it a safer choice. In the e-cigarette industry, PCTG is primarily used for manufacturing oil tanks, heating bases, and casings. Its transparency not only enhances the aesthetic appeal of the products but also allows users to easily monitor the e-liquid levels, thereby improving the overall user experience. \n\nAlthough PCTG has found applications in high-end e-cigarette products, many manufacturers still prefer alternatives like PP or PC due to cost considerations. Special attention must be paid to drying and mold temperature when processing PCTG. The raw material should be dried in a vacuum dryer for 4 to 6 hours prior to injection molding, and the mold temperature should be maintained between 15 to 40\u00b0C to avoid compromising the material's performance. The recommended injection temperature is between 240 to 260\u00b0C to ensure the mechanical properties and clarity of PCTG are preserved.<\/em><\/p>\n

First, PCTG raw materials need to be thoroughly dried in a vacuum dryer for 4 to 6 hours before injection molding, and the recommended drying temperature is set according to the supplier's recommendations.<\/span>Inadequate drying can cause the molecular weight of the polymer to drop and the additives to crack, affecting the color and physical properties of the molded part.<\/span><\/p>\n

During the injection molding process of PCTG, it is recommended to use the direct gate glue feeding method and avoid using hot runner, because long-term high temperature will cause serious degradation of the material. An ordinary screw-type injection molding machine can meet production needs. The processing temperature of the material is usually recommended to be between 240-260\u00b0C, which helps to maintain the mechanical properties and transparency of PCTG.<\/span><\/p>\n
