The storage stability of mixed silicone products, when sold as commodities, is of great significance. If this period is exceeded, structural phenomena will occur, resulting in a deterioration of processing performance. The main cause of the structuring is the hydroxyl groups on the surface of the silica in the rubber compound.
Therefore, studying the structure and dosage of structure control agents is an important part of improving the storage period of mixed rubber. Meanwhile, strengthening the internal mixing process, extending the vacuum internal mixing time, and enhancing the re-mixing effect are all the main measures to improve storage stability
