Why precise moisture control in plastics is crucial for your company’s success?

of Dr. Magdalena Laabs

Have you ever experienced unexpected production defects such as micro-pores, bubbles, or strength problems despite seemingly perfect processing parameters? Did you know that one of the most common and yet underestimated causes of these issues is moisture content in your raw materials?

Moisture – it may sound trivial, but it’s far from being a minor problem. Even trace amounts of water, invisible to the naked eye, can lead to severe financial losses and serious quality issues. So, what's the solution? The answer is simple: precise and reliable moisture measurement using the RBSDMS-IZS-442 Moisture Analyzer.

Which plastics can you test using the RBSDMS-IZS-442 Moisture Analyzer?

This versatile analyzer, based on the accurate Loss On Drying (LOD) method, enables you to test a wide variety of materials, including virgin polymers (granules), recycled plastics (regranulates, regrinds), and powdered materials. Among the materials you can measure are both commonly used structural plastics and specialized engineering materials and elastomers:

Polyolefins

  • Polyethylene (PE) – HDPE, LDPE, LLDPE, MDPE, UHMWPE

  • Polypropylene (PP) – homopolymers, block and random copolymers

Styrenic Plastics

  • Polystyrene (PS) – GPPS (General Purpose), HIPS (High Impact)

  • ABS (Acrylonitrile Butadiene Styrene copolymers)

  • SAN (Styrene Acrylonitrile)

  • ASA (Acrylonitrile Styrene Acrylate)

Engineering and Technical Plastics

  • Polyvinyl Chloride (PVC) – rigid and flexible

  • Polyethylene Terephthalate (PET and recycled rPET)

  • Polyamides (PA) – PA6, PA66, PA12

  • Polycarbonate (PC)

  • Polyoxymethylene (POM, Acetal)

  • Polymethyl Methacrylate (PMMA, Acrylic)

High-Temperature and Specialty Plastics

  • Polyetheretherketone (PEEK)

  • Polysulfone (PSU)

  • Polyvinylidene Fluoride (PVDF)

  • Polyphenylene Sulfide (PPS)

  • Polyetherimide (PEI)

Thermoplastic Elastomers (TPE)

  • Thermoplastic Polyurethane (TPU)

  • Thermoplastic Olefin Elastomers (TPO)

  • Thermoplastic Vulcanizates (TPV)

Natural and Synthetic Rubbers

  • Natural Rubber (NR)

  • Synthetic Rubbers (EPDM, NBR)

The RBSDMS-IZS-442 Moisture Analyzer effectively measures moisture content in virgin plastic granules, recycled materials, powders, and regrinds.

Why is moisture such a significant threat?

Imagine a scenario where you’re handling a significant order, and your finished products suddenly turn out defective. The reason may be trace amounts of moisture present in raw materials, causing pores, bubbles, and weakening the material structure during processing. Besides visible defects, moisture also affects mechanical properties – leading to brittleness, decreased strength, and aesthetic deterioration.

How is moisture measured using the LOD method?

The Loss On Drying (LOD) method is not only one of the most accurate but also straightforward ways to measure moisture. It involves precisely weighing a sample before and after drying under controlled temperatures (40–199°C). The RBSDMS-IZS-442 Moisture Analyzer automatically performs all calculations and displays the results clearly on its LCD screen, significantly reducing human error and ensuring result repeatability.

Are you drying your materials "just in case"?

Many companies unnecessarily consume vast amounts of energy by excessively drying materials without precise measurement. By using a moisture analyzer, you can optimize your drying process – drying only as much as actually needed. This simple step will significantly lower your production costs, while simultaneously helping the environment and supporting sustainability policies.

Not just for plastics industry!

The RBSDMS-IZS-442 Moisture Analyzer also finds applications across other industrial sectors, such as the food industry (milk powder, flour, dried fruits), chemical, pharmaceutical, agricultural (fertilizers, grains), and construction (cement mixtures, mortars).
