1. Silica absorbs moisture in the air during storage and stabilizes its structure, that is, moisture absorption
2. White carbon black compound is easy to form hydrogen bonds and self-agglomerate when mixing, resulting in high Mooney viscosity and difficult mixing process.
3. The hydrophilicity of silica and hydrophobic macromolecules are mutually exclusive, which affects the dispersion of silica in rubber
4. Active hydrogen ions can easily adsorb amine materials such as zinc oxide and accelerators, leading to delayed vulcanization and reduced rubber performance.
