This course is designed for professionals working with washed and dried PET flakes. Whether your material comes from in-house recycling or external suppliers, mastering viscosity, moisture, and thermal stability is key to a successful extrusion process. This course focuses on avoiding common quality losses and maximizing production performance.
Who is this course for?
🟢 For owners and managers of PET recycling and regranulation lines seeking stable and profitable production.
🟢 For extrusion technologists and machine operators working with film, bottle, or fiber-grade PET.
🟢 For those responsible for quality control, technical adjustments, and reducing material loss in PET processing.
🟢 For professionals aiming to understand and stabilize IV (Intrinsic Viscosity), moisture, and mechanical properties of recycled polymers.
Course Objective
The goal of this course is to provide technical know-how for effective PET flake regranulation. You will learn how to monitor and stabilize viscosity, avoid moisture-related defects, and optimize process settings based on the type of PET (A-PET, G-PET, R-PET, etc.). The course also covers decontamination requirements for bottle-grade materials.
Why should you join?
🟢 Learn how to stabilize PET viscosity (IV) and avoid quality loss.
🟢 Understand moisture control and drying procedures for different PET types.
🟢 Discover how to configure machines to reduce thermal degradation.
🟢 Learn how to test and control parameters like MFI, density, and residual moisture.
🟢 Improve product consistency and reduce complaints or batch rejections.
What will you learn?
🟢 How to assess the quality of PET flakes before extrusion
Understand how moisture, contamination, and PET type affect regranulate properties.
🟢 Practical control of IV and process parameters:
• Measurement and interpretation of viscosity
• Impact of residence time, pressure, and screw speed
• Acceptable moisture levels for different PET types
🟢 Optimization of the regranulation process:
• Configuration of drying and degassing systems
• Avoiding viscosity drops and material degradation
• Using additives to enhance granulate performance
🟢 Ensuring food-grade quality in bottle-to-bottle applications:
• Legal and technical requirements for decontamination
• When regranulate is acceptable for preform production
• Common reasons for rejection of PET granulates
🟢 Quality control and real-time monitoring:
• Testing MFI, IV, density, and moisture
• How to stabilize viscosity across batches
• Reducing variation and improving long-term performance
