Although plastic defoaming Masterbatch are of high quality and low price, they should pay attention to the occurrence of these doubts in use, and prevent them in time to prevent unnecessary troubles.
1. Prevent the plastic defoaming masterbatch from absorbing moisture before use.
2. It is better to use immediately once open it.
3. When using plastic defoaming masterbatch, do not heat and dry it together with damp plastic to prevent poor quality during processing.
4. Before using the plastic defoaming masterbatch, check whether the packaging is intact, and heat seal the unused masterbatch as soon as possible.

FAQs
What is Defoaming Masterbatch?Defoaming Masterbatch (also known as Antifoaming Masterbatch or Desiccant Masterbatch) is a specialized functional additive used to effectively eliminate residual moisture and prevent defects such as bubbles, silver streaks, and pockmarks, thereby enhancing the product's appearance and physical properties.Defoaming masterbatch is widely used in plastic processing involving damp raw materials or recycled resins—including film blowing (garbage bags, agricultural films), extrusion (pipes, sheets), injection molding,.
