Moisture Sensitivity

Moisture sensitivity refers to how materials react to exposure to humidity or water, affecting their stability, performance, and usability. This property is critical in industries like pharmaceuticals, food, and electronics, where excess moisture can lead to degradation, clumping, or reduced functionality.

On this page, explore the causes of moisture sensitivity, its effects, and strategies to mitigate risks, ensuring product quality and reliability.

    When Humidity Spikes Hit Your Powder Flow

    Average conditions rarely tell the full story. Short humidity spikes can change surface moisture, cohesion, and bulk behavior long before specifications move. Treat humidity spikes powder flow interactions as a design parameter, not background noise, and you prevent many “mysterious” flow and caking problems. Why a stable average [...]

    Powder Certificate of Analysis vs Reality: Why Incoming Tests Matter

    A powder certificate of analysis (CoA) confirms identity and basic properties, but not real handling behavior. Treat every powder certificate of analysis as a starting point and support it with lean incoming tests for flow, moisture, and fines before you decide whether a batch truly fits your process. Table [...]

  • Powder wettability in food and feed shown by food powder dispersing in water

    Inside Perspective of Powder Wettability in the Food and Feed Industries

    Powder wettability in food and feed determines how fast powders sink, hydrate, and disperse. By controlling surface fat, agglomeration, and surfactants, processors reduce clumping, energy use, and fines while improving product quality, pellet strength, and line efficiency.

  • Photorealistic laboratory setup illustrating dew point vs water activity in powder processing, showing a powder sample in a steel dish with a hygrometer measuring humidity and temperature.

    Dew Point vs Water Activity in Powder Processing

    For powders, dew point vs water activity defines control. Dew point governs the air. Water activity governs the material. Control both, or moisture wins. Stop Mixing Them Up Teams often blur these terms. Dew point vs water activity is not a nuance. Dew point describes air moisture. [...]

    PFAS vs PTFE in 2025: What’s Really Changing for Powder-Based Manufacturing

    PFAS PTFE powder manufacturing industries will face policy tightening across Europe. PTFE’s role as a binder and in plant materials sits in the spotlight. The next 12–24 months will shape supply, compliance costs, and the technical direction of powder-based manufacturing. Table of contents PFAS PTFE [...]
