Product Description

Defoaming masterbatch (also known as dehumidifying masterbatch and absorbent masterbatch) is suitable for the production enterprises of PE and PP damp raw materials and recycled plastic products. The raw materials contain trace moisture or moisture, which has a very serious impact on the production of plastic products. Therefore, enterprises generally use drying equipment to dry plastic, which is a great waste of energy and human resources, and increases the life of products. The cost of production, and the use of this defoaming masterbatch, only need to be added to the raw material to mix evenly, without any adjustment of the production process of the product, can eliminate all the problems caused by water bubbles, moire, cracks, spots and so on.
  

When the defoaming masterbatch is stirred with the moisture-affected plastic material directly, the product can be processed and produced. For example, the proportion of defoaming masterbatch added is 1%-2% for blown film production. If used in sheet and injection moulding production, the addition ratio is 2%-5%. If used in pipe production, add 2%-5%. Specific addition proportion should be added at the discretion of users according to the moisture condition of plastics.
