Applications of Magnesium Chloride Desiccant

Reliable High-Humidity Moisture Protection for Industrial Packaging, Storage, and Shipping

Rundun New Materials delivers high-performance industrial desiccant solutions designed for demanding logistics, export, and storage environments worldwide.

Why Choose Rundun New Materials Magnesium Chloride Desiccant?

Magnesium chloride desiccant is a high-performance moisture absorber widely used in industrial packaging, transportation, and storage applications where humidity control is critical. Due to its strong hygroscopic and deliquescent properties, magnesium chloride rapidly absorbs moisture from the air and converts it into a stable solid block, making it especially effective in high-humidity and long-duration exposure environments.

Compared with traditional desiccants such as silica gel or clay, magnesium chloride desiccant offers significantly higher moisture absorption capacity, allowing industrial users to achieve reliable protection with fewer units and lower overall cost. It is commonly selected for export packaging, container shipping, warehouse storage, and industrial equipment protection.

Technical Highlights:

  • Up to 300% moisture absorption capacity(weight at 50°C, 90% RH, SGS tested)
  • Turns absorbed moisture into a solid block with no leakage, ensuring safe and mess-free use in enclosed spaces.
  • Complies with REACH, RoHS, SGS, and MSDS certifications for export and industrial use.
  • Constructed with durable Tyvek® Paper / Dulai Paper packaging to prevent dust and enhance moisture protection.

How It Works

Rundun New Materials magnesium chloride desiccant is formulated with anhydrous MgCl2 plus starch-based polymer. When exposed to ambient moisture:

  • The MgCl2 triggers a chemical hygroscopic reaction that absorbs water vapor from air.
  • Moisture is permanently locked into a solid mass, eliminating risk of liquid drip or reverse diffusion.

This makes it highly effective in environments with wide humidity ranges (10%-100% RH, -20°C to 90°C) - ideal for protective packaging, storage, and extended transit conditions.

Primary Industrial Application Scenarios

Packaging Moisture Protection

Rundun New Materials magnesium chloride desiccant is widely used inside industrial and export packaging to protect moisture-sensitive products.

Typical Applications:

  • Electronics and electrical components
  • Auto parts and precision metal components
  • Hardware, tools, and mechanical assemblies

Moisture Risks Addressed:

  • Corrosion and oxidation
  • Mold and mildew formation
  • Degradation of sensitive materials

Desiccant units are placed directly inside cartons, sealed packaging, or export crates to ensure consistent humidity control throughout the supply chain.

Transportation and Logistics Protection

During long-distance shipping, especially sea freight, cargo is exposed to extreme temperature changes and high humidity. Magnesium chloride desiccant is commonly used to protect goods from moisture damage caused by container rain and condensation.

Common Use Scenarios:

  • Sea freight containers
  • Long overland transport
  • High-humidity regional transit

Rundun New Materials strips and sachets help prevent container rain, condensation, and corrosion, making them ideal for marine and intermodal logistics.

Warehouse and Storage Humidity Control

Uncontrolled humidity in warehouses can cause long-term damage to stored goods. Rundun New Materials magnesium chloride desiccant helps create a stable, dry micro-environment in enclosed spaces.

Rundun New Materials desiccants help maintain dry environments for:

  • Spare parts inventory
  • Finished goods storage
  • Sensitive industrial equipment

By reducing excess moisture, magnesium chloride desiccant extends product shelf life and reduces maintenance and replacement costs.

Industrial Equipment and Machinery Protection

Rundun New Materials magnesium chloride desiccants are widely used inside enclosed equipment spaces to protect sensitive industrial systems from internal condensation.

Typical Equipment

  • Electrical control cabinets
  • Switchgear and power distribution boxes
  • CNC machines and industrial systems

Effective moisture control improves operational reliability and reduces downtime.

Magnesium Chloride vs Other Desiccants

Compared with silica gel and clay desiccants, Rundun New Materials magnesium chloride desiccants provide:

  • High-humidity performance: Up to 300% absorption (MgCl2-based) vs lower rates of silica gel.
  • Leak prevention: Solid block formation provides safer use than gel - leakage-prone types.
  • Wide temperature range: Performs in -20°C to 90°C environments.
  • Greater efficiency for long-term shipping and storage

These characteristics make Rundun New Materials magnesium chloride desiccant especially suitable for industrial packaging, container shipping, and high-humidity applications, where moisture damage leads to significant quality issues or loss.

How to Choose the Right Magnesium Chloride Desiccant

To select the optimal Rundun New Materials magnesium chloride desiccant, consider:

  • Size and volume of the enclosed space
  • Expected humidity level and exposure duration
  • Transportation conditions and route
  • Required absorption capacity and packaging format

Professional selection ensures optimal moisture protection and cost efficiency.
