Color Change Desiccant Packs Blue to pink Silica Gel Desiccant Bag

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Color-Indicating Moisture Absorption: The desiccant packs change color from blue to pink when fully saturated, providing a visual indicator for replacement.
  • High-Capacity Silica Gel Core: Made of 99.6% pure silica gel (SiO₂), these packets efficiently absorb moisture to protect electronics, documents, and food from humidity damage.

Key features

  • 1. Advanced Color-Change Material Technology

  • With cobalt chloride-activated silica gel, monitor moisture absorption through a visible color shift from blue to pink. This real-time indication ensures timely replacement, maintaining optimal dryness.

  • 2. RoHS-Certified Safety

  • With RoHS certification, ensure compliance with strict electronic component safety standards, making it ideal for protecting sensitive devices without exposing them to hazardous materials.

  • 3. High-Purity Silica Gel Absorption

  • With 99.6% pure silica gel, achieve up to 40% higher moisture absorption capacity than standard desiccants*, providing superior protection for electronics, documents, and food storage.

  • 4. Multi-Scenario Adaptability

  • With versatile application design, safeguard against moisture in diverse environments—from home storage of food to industrial equipment preservation, ensuring reliability across use cases.

  • 5. Visual Interactive Monitoring

  • With built-in moisture saturation indicators, eliminate guesswork by tracking effectiveness through color changes, unlike traditional desiccants that require manual inspection.

Supplier's note

  1. Technical Breakthroughs:

    • The color change indicator (blue to pink) enables real-time monitoring, reducing over-saturation risks.
    • 99.6% silica purity ensures 30%+ moisture absorption efficiency, outperforming standard desiccants.
    • RoHS compliance expands usability in electronics and medical devices, avoiding hazardous materials.
  2. Optimal Version Selection:

    • Base Model: Ideal for general use (e.g., food packaging, home storage) where cost-efficiency is key.
    • Advanced Model: Suitable for industrial applications (e.g., machinery protection) needing faster saturation alerts.
    • Pro Model: Best for critical environments (e.g., semiconductor manufacturing) requiring ultra-high purity and multi-certification compliance.

With the Pro version’s 42% adsorption capacity, you can protect high-value electronics from corrosion 20% more effectively than traditional silica gel. Pair this with its ISO 9001 certification to ensure quality control in global supply chains.
