Polyethylene-Based Grey Desiccant Masterbatch for Moisture Removal
in Injection Moulding
Stable Supply with Customizable Grades and Over 14 Years of
Manufacturing Expertise
Product Overview
We offer a comprehensive range of desiccant masterbatch products
designed to address moisture-related challenges in plastic
processing. Our product line includes multiple grades tailored to
specific application requirements:
- PE-200: Standard grade for general-purpose moisture control
- PE-300: Enhanced dispersion for thin-wall injection molding
- PE-400: High-flow formulation for complex structural parts
- PE-500: Premium grade with extended moisture protection period
- Black Desiccant Masterbatch**: UV-stabilized version for outdoor
applications
All grades are available in two particle size distributions to
accommodate different processing equipment and dispersion
requirements.

Applications
This desiccant masterbatch effectively eliminates moisture in
recycled materials including polyethylene, polypropylene, mineral
fillers, and various functional additives. Its proven performance
makes it particularly valuable in:
- Agricultural Films: Greenhouse covers, mulch films, and silage
protection sheets
- Injection Molded Components**: Automotive interiors, consumer
products, and industrial parts
- Blown Film Applications: Packaging films, carry bags, and
protective wraps
- Extrusion Products: Pipes, profiles, and technical sheets
Recommended Usage
Standard incorporation rate: 1–5% by weight. The optimal ratio
should be determined based on:
- Initial moisture content of the recycled material
- Specific processing method and parameters
- Required final product properties
Adjustments can be made to address particularly challenging
moisture conditions or specialized performance requirements.
