Solving the problem of “foaming and bursting” in plastic processing – Analysis of the value of defoaming masterbatch

Many plastic product factories, especially those using recycled materials or wet raw materials, often encounter such problems during the production process:

Bubbles, holes or dragging of film products

Foaming, whitening and cracking on the surface of injection molded products

Unable to produce in batches stably, affecting delivery time

Most of these problems are caused by excessive moisture content in raw materials. The traditional method is through drying, but this not only increases energy consumption, but also increases the burden on equipment and labor. At this time, a simpler and more effective solution has emerged-defoaming masterbatch.

What is defoaming masterbatch?

Defoaming masterbatch is a functional masterbatch used to absorb or eliminate moisture during plastic processing. It contains special hygroscopic ingredients (such as active inorganic water absorbents). By mixing it in plastics, it can quickly absorb free moisture in the raw materials, thereby preventing defects in the product due to water vapor.

Why is defoaming masterbatch recommended?

1. Reduce energy consumption, no need for additional drying equipment
   After using defoaming masterbatch, users can save a lot of electricity and labor costs by eliminating the traditional high-temperature drying step, especially in areas with rising electricity prices or strict environmental protection requirements.
2. Simple operation, direct mixing and use
   The masterbatch is granular and can be directly mixed with the main material without changing any production process. It has strong adaptability, flexibility and convenience.
3. Strong moisture absorption and significant defoaming
   Our defoaming masterbatch can absorb free water and adsorbed water in the raw materials in a short time, which is suitable for scenes with high humidity or using recycled materials.
4. Wide range of applications
   It is widely used in the fields of film blowing, injection molding, extrusion, wire drawing, pipe production of PE, PP, LDPE, HDPE and other materials, especially suitable for the field of recycled plastics.

Our advantages:

Multiple models available (fast type, high content type, anti-reabsorption type)

The amount of addition can be adjusted according to the moisture content of the raw materials, generally 1%-5%

Continuous supply, support for customized formulas

Provide free sample testing and technical guidance

In the context of unstable raw material quality and increasingly stringent environmental protection requirements, defoaming masterbatch is not only an emergency tool, but also a tool to improve production line efficiency in the long term.
