Desiccant masterbatch (anti moisture masterbatch) is a functional masterbatch primarily used to solve moisture-related issues and improve the quality of plastic plastics. These masterbatches address the problems during the processing due to the presence of moisture in hygroscopic polymers and pigments. In this article, we understand what desiccant masterbatch is and how it works, shedding light on its significance in controlling moisture levels in plastic products.
What is Desiccant Masterbatch?
A desiccant masterbatch (anti moisture masterbatch) specially designed to absorb moisture in plastic resins. This is because the moisture present in the plastic can result in defects such as fish eyes, bubbles, discolouration and brittleness. This is typically seen in applications such as packaging materials, where high clarity and aesthetic appeal are crucial. The desiccant masterbatch eliminates humidity and enhances the extrusion and injection molding process for a smoother finish, reducing defects and rejections. Want to manage moisture content and achieve consistent product quality efficiently? Perfect Colourants & Plastic Pvt.Ltd has been at the forefront of innovative masterbatch solutions. We are a trusted Desiccant Masterbatch manufacturer in India among clients for helping them maintain product integrity and achieve high-quality finishing.
How Desiccant Masterbatch Work?
The science behind desiccant masterbatch is that it chemically binds moisture during the processing, preventing the moisture molecules from interacting with plastic. These masterbatches are pivotal for the extrusion and molding process, where higher temperatures can cause the water in the material to form air bubbles. The desiccant MBs bind the water, enhancing the mold flow and stabilizing the plastic material.
Types of Desiccant Masterbatches
Different types of desiccant masterbatches are formulated for specific applications and countering different moisture control needs in plastic processing.
Silica gel-based Desiccant: These types of desiccant masterbatches are suitable for application that needs high-absorption of moisture without compromising on plastic’s clarity and colour.
Zeolite-based Desiccant: These desiccants exhibit excellent hygroscopic properties that effectively absorb moisture, particularly in recycled plastic materials.
Calcium Oxide-based Desiccant: These desiccants are ideal for high-humidity conditions and for plastic polymer moisture control.
How to Choose the Right Desiccant Masterbatch?
The most suitable desiccant masterbatch depends on your specific requirements, plastic types, moisture levels and processing method.
Compatibility: Choose a desiccant MB compatible with the plastic polymer processing.
Moisture Absorption Requirements: Applications with higher moisture content need a higher absorption capacity desiccant.
Processing Technique: Some MBs are more suitable for higher temperatures, making them ideal for extrusion and injection molding processing.
