Dimethyl silicone oil is a colorless, odorless, transparent liquid. Its chemical name is polydimethylsiloxane. Although its name sounds professional and unfamiliar, it has already permeated every aspect of modern industrial production and daily life, and can be regarded as an indispensable "multifunctional material". 
Its core charm stems from its unique molecular structure. Unlike traditional hydrocarbon-based lubricants, the main chain of dimethyl silicone oil is composed of alternating silicon and oxygen atoms, while the side chain is methyl. This structure endows it with a series of outstanding physical and chemical properties: excellent resistance to high and low temperatures (the working temperature range can reach -50℃ to above 200℃), excellent electrical insulation, outstanding hydrophobicity, and extremely low surface tension. 
For this reason, dimethyl silicone oil has proven to be highly effective in the industrial sector. In the fields of precision machinery and electronic electrical engineering, it is used as high-grade lubricating oil and damping fluid to protect equipment from running unstably in a wide temperature range. In chemical production, it is an efficient defoamer, capable of quickly eliminating various harmful foams. In mold manufacturing and demolding processes, it becomes an ideal demolding agent, ensuring that products can smoothly and completely be removed from the mold. 
It can be said that dimethyl silicone oil, with its stable, safe and efficient performance, quietly supports the smooth operation of numerous industrial processes. It is a low-key "lubrication star" behind modern manufacturing.
