Efficient defoaming masterbatch (also known as moisture removal masterbatch or absorbent masterbatch) is suitable for enterprises producing products using various types of PE and PP recycled plastics. The trace amount of moisture contained in raw materials has a very serious impact on the production of plastic products. Therefore, enterprises generally adopt the addition of drying equipment to dry plastics, which is a great waste of energy and manpower, and increases the cost of products. By using this master batch, it is only necessary to add it to the raw materials without making any adjustments to the production process of the product, and all problems caused by moisture such as bubbles, cloud lines, cracks, spots, etc. can be eliminated.
