Desiccant Masterbatch

Mega Plast’s Desiccant Masterbatch is designed to solve one of the most common challenges in plastic production: excess moisture in raw materials. Whether you’re working with virgin resin or recycled plastic, moisture can cause serious problems such as bubbles, silver streaks, poor surface finish, and reduced mechanical strength.

Our Desiccant Masterbatch contains high levels of active Calcium Oxide and is compatible with various polymers such as PP and PE. With a recommended dosage of just 1–2%, it effectively removes moisture during processing — helping to improve product quality, reduce waste, and eliminate the need for pre-drying.

This product is especially useful for applications like blown film, injection molding, woven bags, and sheet extrusion, where moisture can significantly affect performance and appearance.

Backed by Mega Plast’s strict quality control and the integrated production strength of Nhat Huy Group, our Desiccant Masterbatch offers a simple, cost-effective solution for stable and efficient plastic manufacturing.

Why Manufacturers Need to Use Desiccant Masterbatch?

1. Removes Moisture in Plastic Materials

Plastic resins — especially PET, Nylon, ABS, PC, and even PE/PP if not stored properly — often absorb moisture from the air. Recycled plastic usually contains even more moisture.
When these materials are processed at high temperatures (in injection molding, extrusion, or blow molding), the moisture turns into steam, which causes surface and internal defects in the final product.

Desiccant Masterbatch helps remove this moisture directly during production, reducing the risk of defects and improving product quality.

2. Prevents Surface Defects Caused by Moisture

Using wet plastic can cause visible surface issues such as:

Voids or bubbles: Steam trapped inside the material during processing.
Silver streaks or splay marks: Silvery lines caused by moisture escaping from the resin.
Fish eyes: Small round marks on film surfaces.
Rough or uneven surfaces.

Desiccant Masterbatch absorbs the moisture inside the resin and helps prevent these problems, resulting in smoother and cleaner products.

3. Improves Mechanical Properties

Moisture can damage the strength of plastic, especially during high-heat processing. It may cause loss of tensile strength and impact resistance due to hydrolysis.
By removing water from the material, Desiccant Masterbatch helps keep the plastic’s physical properties strong and stable.

4. Increases Production Efficiency & Reduces Waste

Moisture-related defects often lead to higher rejection rates. Using Desiccant Masterbatch helps lower the number of faulty products, which means:

Less material waste
Shorter production times
Lower energy costs
More stable production runs

5. Reduces or Eliminates the Need for Drying

Traditionally, moist plastic needs to be dried for several hours before production, using extra machines and electricity.
With Desiccant Masterbatch, you can mix it directly into the resin and begin processing — no separate drying step required.
This is especially useful for factories that don’t have drying systems or want to save energy and time.

6. Helps Reduce Oxidation During Processing

In some grades, Desiccant Masterbatch includes additives that reduce oxidation caused by heat and moisture during processing.
This protects the plastic from yellowing, brittleness, and other signs of degradation — especially in high-temperature applications.

7. Works Well with Low Dosage (1–2%)

You only need a small amount — typically 1–2% — to achieve good results. This makes Desiccant Masterbatch a cost-effective solution for handling moisture without adding much to the overall production cost.

8. Makes Recycled Plastic Easier to Use

Recycled plastic typically contains more moisture than virgin material. Desiccant Masterbatch helps remove this moisture, making it easier to use recycled plastic in more types of products — while still meeting quality standards.
