PETG (Polyethylene Terephthalate Glycol) is a highly versatile copolyester. Achieving the perfect finish in thermoforming or extrusion starts with moisture management. The critical PETG drying temp and time balance is essential to prevent degradation (hydrolysis). Typically, drying is performed at 65°C-70°C for 4-6 hours, ensuring moisture levels stay below 0.04%.
LIANDA MACHINERY, as a leader since 1998, leverages proprietary IRD (Infrared Rotary Dryer) technology to reduce this energy-intensive process to just 20 minutes, delivering superior quality for global manufacturers.
China's manufacturing ecosystem provides an unrivaled advantage in scale, R&D agility, and cost-efficiency. Lianda Machinery represents this shift—integrating German patent-based drying technologies with localized, high-speed engineering to serve 80 countries worldwide.
Q: What is the ideal drying temperature for PETG?
A: Standard desiccant systems require 65-70°C. With our advanced IRD systems, we optimize thermal radiation for faster, more uniform drying.
Q: How does moisture affect PETG transparency?
A: Excess moisture causes "bubbles" and haze. Proper drying ensures the molecular integrity of the polymer, maintaining high optical clarity.
