Abstract
Description
Technical Field

[0002] Drometrizole trisiloxane is an organosilicon compound, also known as cresol trisiloxane. Its chemical structure contains cresol and siloxane groups. Drometrizole trisiloxane is often used as a surface treatment agent, lubricant and lubricating additive. Taking advantage of the increased brittleness of materials under low temperature conditions, drometrizole trisiloxane is crushed under low temperature conditions to maintain the stability of its chemical properties and structure. Drometrizole trisiloxane may decompose or undergo other chemical reactions at high temperatures, resulting in a decrease in product quality or the production of undesirable products. Therefore, low-temperature crushing can reduce the generation of heat and reduce the impact on heat-sensitive materials, thereby ensuring the stability of the crushing process and product quality.
