Vermiculite bagged goods

Vermiculite is a lightweight, porous mineral granulate that fills cavities, cushions, and binds liquids.


Ideal for sensitive products, electronics, glass/ceramics, samples, and the safe temporary storage of rechargeable batteries/batteries. Non-conductive, non-flammable (>1000 °C), reusable.

    Häufig gestellte Fragen (FAQ)

    Which grain size is right?

    Mittel–grob ist der Allrounder: gute Polsterung, einfache Dosierung, wenig Staub. Fein bindet schneller, kann aber staubiger sein. Für sehr sauberes Handling gibt es Vermiculite-Kissen (portioniert, staubarm).

    Is vermiculite electrically conductive or flammable?

    Nein. Vermiculite ist nicht leitend und nicht brennbar. Referenzwerte: Sintertemperatur 1260 °C, Schmelzpunkt 1315 °C.

    How does vermiculite perform thermally?

    Es bietet eine spürbare Pufferwirkung gegen Temperaturspitzen. Die Wärmeleitfähigkeit liegt bei ca. 0,07 W/mK (DIN 4108).

    How heavy is the material — does it affect shipping weight?

    Die Schüttdichte liegt bei ca. 80–125 g/L (DIN 1060). Vermiculite ist sehr leicht im Verhältnis zum Packvolumen und daher effizient für Hohlraumfüllung.

    Can I reuse vermiculite, and how should I dispose of it?

    Ja, trocken und sauber gebliebenes Material kann wiederverwendet werden. Kontaktierte/verschmutzte Mengen entsprechend den lokalen Vorgaben entsorgen.

    Is vermiculite “neutral” and compatible with materials?

    Der pH-Wert liegt bei ca. 7,5 (nahe neutral). Das mineralische, poröse Granulat ist mit vielen Oberflächen kompatibel. Bei sensiblen Anwendungen empfehlen wir einen kurzen Vorab-Test.

    Do you offer samples or advice on the right grain size?

    Ja. Wir bieten kostenlose Muster und eine kurze Fachberatung, um Körnung und Menge auf deinen Prozess abzustimmen. Größe/Körnung einfach anfragen.
