December 30, 2025 - Chain Plastic Network released a guide on silane dispersants, uncovering their core value in the plastic and rubber industries. Based on a unique chemical structure (Y-R-Si-X₃), silane dispersants achieve surface functionalization through the reaction between alkoxy groups and filler hydroxyl groups, while enhancing compatibility with polymer matrices via organic functional groups to form a protective layer that prevents particle agglomeration.
    These additives offer four key advantages: optimizing the dispersion and wettability of fillers and pigments, reducing surface defects and improving mechanical properties; lowering the viscosity of filled resins, expanding processing windows and increasing output; alleviating the curing inhibition of thermosetting resins to boost reaction efficiency; and enhancing the electrical properties of composite materials, which remain stable even after boiling water aging. In mineral filler treatment, silane dispersants are widely applicable to titanium dioxide, talc, wollastonite, etc., improving material hiding power, stiffness and dimensional stability respectively, and helping masterbatch production achieve high filling capacity and efficiency.
    As important modification additives in the rubber and plastic industry, silane dispersants are driving innovations in processing technologies and quality upgrades of related products with dual advantages in performance and cost.
