Plastic Desiccant Masterbatch - China

PE/PP plastic desiccant masterbatch is a functional material designed specifically for removing moisture from recycled plastic materials such as polyethylene (PE) and polypropylene (PP).

This desiccant masterbatch is especially suitable for applications where moisture causes defects like bubbles, lines, or poor surface finish in plastic products.

Recycled polyethylene (PE) and polypropylene (PP) often contain residual moisture.

This can lead to defects such as water bubbles, surface lines, and even processing failures during molding and extrusion.

Our plastic desiccant masterbatch, also known as drying agent masterbatch, is developed to solve these problems efficiently.

By adding a small amount of this moisture absorbent masterbatch directly to the raw plastic material, users can eliminate the need for traditional drying procedures.

This method simplifies the process and reduces energy consumption while improving product quality and environmental protection.

This advanced cao desiccant masterbatch, based on calcium oxide formulation, absorbs moisture effectively.

It acts as a powerful plastic dehydration additive, improving production stability across various plastic processing techniques.

Product Features

Effectively reduces bubbles, pores, and flow marks caused by moisture.

This moisture absorbent masterbatch can absorb water up to 20% of its own weight.

No need to change existing production equipment or process.

Environmentally friendly solution – developed as a lime desiccant masterbatch alternative.

Works as a combined dehumidifier masterbatch and drying masterbatch for better compatibility with various plastic types.

Application Field

Our plastic desiccant masterbatch is widely used in:

Film blowing

Injection molding

Sheet and pipe extrusion

Bubble film and aluminous plastic boards

Toolboxes and plastic barrels It is especially effective in reworked plastic materials, ensuring stable performance without additional drying equipment.

This drying agent masterbatch is particularly useful for manufacturers who require high efficiency and cost savings in recycling or low-moisture environments.
