Moisture in Plastics - Understand and Solve Problems
(Course No.: LAB-P3-2003)
Part 3 of a 3-course training program on moisture in plastics
This course is the third part of the complete Rolbatch Academy training program dedicated to moisture in plastics.
Part 1 introduces the fundamentals of moisture and basic concepts needed to understand the topic.
Part 2 teaches the practical operation of the moisture analyzer and how to perform LOD (Loss On Drying) measurements correctly.
Part 3 (this course) shows how moisture affects processing, product quality, process stability and defect formation. You will also learn diagnostics, root-cause analysis and corrective as well as preventive actions.
Together, all three courses form a complete, professional learning system, allowing you to work without guessing, without costly mistakes and without unnecessary waste.
Understand and eliminate moisture-related problems
Moisture is one of the most underestimated parameters affecting process stability, surface quality and mechanical performance of plastic products.
Even minor amounts of moisture can lead to:
- bubbles,
- micro-porosity,
- streaks,
- surface dullness,
- brittleness,
- reduced mechanical strength,
- unstable flow or pressure pulsation.
The influence of moisture becomes even more complex when working with modified materials containing pigments, carbon black, TiO₂, mineral fillers, antistatics, UV stabilizers or flame retardants. These additives change the way the material absorbs or releases moisture, which directly affects product quality and process behavior.
This is why this course is so important: it teaches you how to recognize, diagnose and eliminate moisture-related issues that cost manufacturing companies the most.
What will you learn in this course?
🟠 how moisture affects melt rheology, flow behavior and pressure stability
🟠 how to identify typical moisture-related defects such as bubbles, streaks, micro-porosity, dull surfaces, brittleness
🟠 how additives (carbon black, pigments, TiO₂, chalk, talc, UV stabilizers, antistatics, flame retardants) change moisture behavior in plastics
🟠 how to combine moisture test results with MFI and density to distinguish moisture effects from degradation
🟠 how to diagnose problems from symptom to root cause
🟠 how to implement corrective and preventive actions that truly stabilize production
🟠 how to build an internal moisture control system to reduce the number of complaints
This knowledge allows you to improve production quality immediately.
Who is this course for?
This course is dedicated to professionals who must understand how moisture affects product quality and process behavior:
🟠 process engineers
🟠 extrusion and molding operators
🟠 production managers and shift leaders
🟠 laboratory and quality control teams
🟠 specialists analyzing process issues
🟠 companies working with virgin polymers, recyclates, compounds and color concentrates
If your company experiences defects, unpredictable issues, differences between batches or recurring complaints, this course is essential.
Why companies choose this course
Because they want to:
🟠 understand where bubbles, streaks or porosity come from
🟠 distinguish moisture-related defects from degradation or contamination issues
🟠 make informed decisions: continue production, stop the line, dry the material, adjust parameters or reject a batch
🟠 work with a consistent, standardized diagnostic method
🟠 significantly reduce scrap and complaint costs
🟠 stabilize the process and improve repeatability
The knowledge gained here pays for itself faster than the cost of one defective batch.
Course Format - How You Will Learn
This course includes:
- PDF materials and e-books with examples, illustrations and process diagrams
- audio recordings you can listen to outside the office or production floor
- quizzes to help reinforce key learning points
The course is designed to guide you step by step from identifying process deviations during production to making the correct technical decision.
