In the competitive realm of plastic processing, understanding "How long to dry PETG" is more than a technical specification—it is a critical success factor. PETG (Polyethylene Terephthalate Glycol) is highly hygroscopic. If moisture is not strictly controlled to below 50ppm, hydrolysis occurs during extrusion, resulting in brittle parts and reduced optical clarity. At Lianda Machinery, we leverage decades of engineering expertise to redefine drying standards.
Traditional desiccant dryers often require 4-6 hours to achieve necessary moisture levels. Our Infrared Rotary Drying (IRD) technology revolutionizes this by combining heating and crystallizing in one step. Drying time for PETG is reduced to as little as 20 minutes, offering a 45-50% energy saving compared to legacy systems.
Lianda Machinery adheres to ISO9001 and CE certifications, ensuring our solutions meet the rigorous demands of global markets from Europe to the Americas. Our commitment to sustainable innovation is backed by our German patent-based drying technology, specifically engineered to handle complex materials like PETG, PEI, and PPSU with precision.
PETG is hygroscopic; moisture absorption leads to chain scission during melting, resulting in hazy, brittle, and low-quality end products.
Typically 65°C-70°C for PETG. Our IRD systems optimize this via precise thermal control to prevent clumping.
Using conventional dryers: 4-6 hours. Using Lianda Infrared Crystallization Dryer: 20 minutes.
