When dealing with chemical raw materials, safety is always the top priority. Although hexamethylcyclotrisiloxane (D3) has a wide range of applications, understanding its physicochemical properties is crucial. Identified by CAS number 541-05-9, it typically appears as a white crystalline powder with a melting point of approximately 64.5°C. Notably, D3 is flammable, with a flash point of only 35°C; this means it must be kept strictly away from ignition sources and high-temperature environments during storage and transportation. Furthermore, while insoluble in water, it is soluble in organic solvents such as benzene. Users must fully understand these characteristics to ensure absolute safety during production and handling while effectively leveraging the substance to create value.
