PP/PE Carrier Dessicant Masterbatch/Defoaming Masterbatch

The amount of masterbatch to be added depends on several factors, such as the moisture content of the polymer, the severity of foam formation in the process, and the specific requirements of the end - product. Generally, a dosage of 1% - 5% by weight of the polymer is recommended. However, it is advisable to conduct small - scale trials to determine the optimal dosage for your specific production process.

Yes, the masterbatch is designed to be compatible with a wide range of PP and PE grades. Whether it is high - density polyethylene (HDPE), low - density polyethylene (LDPE), or different types of polypropylene, the masterbatch can effectively perform its desiccant and defoaming functions. However, minor adjustments in the dosage may be required depending on the specific grade and properties of the polymer.

When stored under recommended conditions (cool, dry, well - ventilated area between 5C - 35C), the shelf - life of the masterbatch is approximately 12 months. It is important to check the masterbatch periodically for any signs of caking, discoloration, or changes in its physical properties. If stored properly, the masterbatch will maintain its performance within this time frame.
