The defoaming masterbatch is a new functional masterbatch with high technology content developed independently and used to remove water, bubbles and defects during the processing of plastic products. By addingthe defoaming mas- terbatch, the drying of raw materials and other processes can be omitted, the cost of plastic products can be reduced, the production efficiency can be improved, and the comprehen- sive mechanical properties and appearance quality of plastic products can be greatly enhanced.The defoaming master- batch, whichhas no toxicity, pollution or adverse effect on the performance of plastic products, is a hi-tech product inde- pendently developed and protected by the intellectual property rights.
