What Is The Hidden Difference Between Market Vinyl Silicone Oil & High-Purity Synthetic Grade?
  • What Is The Hidden Difference Between Market Vinyl Silicone Oil & High-Purity Synthetic Grade?


    Compare: Market Ordinary Vinyl Silicone Oil VS Our Synthetic Vinyl Silicone Oil

    ❌ Market Common Vinyl Silicone Oil

    ☐ Mostly repackaged & blended oil, NOT self-synthesized 

    ☐ Big batch-to-batch quality fluctuation 

    ☐ High cyclic oligomers & volatile content 

    ☐ Residual heavy metals / impurities → easily trigger platinum catalyst poisoning, curing failure 

    ☐ Fixed specs, difficult to customize vinyl content & viscosity 

    ☐ Final silicone parts easy to yellow, shrink and age fast



    ✅ Our Vinyl Terminated Silicone Oil (Core Selling Points)

    ☑ 100% original chemical synthesisMade from DMC raw materials in-house, not simple blending & repackaging.

    ☑ Stable batch consistencyPrecise control on molecular chain structure. Little performance difference between batches, support your continuous mass production.

    ☑ Low cyclic & low volatileLess small molecule precipitation. Suitable for high-end electronics, medical and food contact export applications.

    ☑ Ultra-low harmful impuritiesAvoid platinum catalyst poisoning completely. No curing failure risk, much higher production yield.

    ☑ Fully customizableViscosity, vinyl content and technical parameters can be tailored to match your formulation.

    ☑ Excellent final part performanceCured silicone has low shrinkage, long-term anti-yellowing, good heat resistance & aging resistance.



    Vinyl Silicone Oil – Market Ordinary Grade VS Our Original Synthetic Grade
    Comparison ItemMarket Ordinary GradeOur Original Synthetic Grade
    Production SourceBlended/re-packaged from multiple sources; opaque originFactory-synthesized; fully traceable source
    Vinyl ContentInconsistent, varies batch to batchPrecisely controlled, uniform and stable
    Appearance / TransparencyProne to yellowing and cloudinessHigh transparency, colorless and clear
    Low MW Components / VolatilesHigher content, easy to volatilizeLow low-molecular-weight content, fewer volatiles
    Batch ConsistencyObvious differences between batchesStrong batch-to-batch consistency
    Viscosity ControlWide range, label often inaccurateAccurate viscosity, matches specification
    Compatibility with Pt CatalystEasily poisons catalyst, incomplete cureGood compatibility, full curing
    Storage StabilityProne to degradation, shorter shelf lifeStable in storage, longer shelf life
    COA (Certificate of Analysis)Missing or incompleteFull COA provided
    Environmental ComplianceOften lackingRoHS / REACH compliant
    Application PerformanceMore defects, lower yieldStable performance, higher finished-good yield
