In the cutting-edge manufacturing fields such as semiconductors, optical fibers, and avionics, the purity grades of organic silicon materials often serve as the key variables determining the yield and performance of products. The trace amounts of cyclic compounds (D3-D10) and small molecular volatiles remaining in ordinary industrial-grade silicone oil may escape under high temperature or vacuum conditions, causing coating bubbles, wafer surface contamination, or optical component fogging. Our company's product series of low-volatile silicone oil LS, with strict control of volatile content and extremely low residual cyclic compounds, provides a reliable raw material choice for applications demanding high purity.


1. Product Series Specifications and Core Indicators


The low-volatile silicone oil LS series includes three categories: methyl silicone oil, vinyl silicone oil, and hydrogen-containing silicone oil, corresponding to the models IOTA-M-X, IOTA-Vi-X, and IOTA-H-X. Users can flexibly select based on downstream process requirements.


The volatile content of the product series methyl silicone oil and vinyl silicone oil is controlled below 0.2% at 150 degrees Celsius for three hours, and the residual mixed cyclic compounds (D3-D10) content is less than 300 ppm. The methyl silicone oil and vinyl silicone oil offer various viscosity specifications ranging from 100 to 10,000 square millimeters per second, while the viscosity range of hydrogen-containing silicone oil is from 20 to 300 square millimeters per second, with a volatile content not exceeding 0.5%.


2. Core Performance Advantages and Application Value


The core value of the product series low-volatile silicone oil LS lies in its high purity. The residual D3 to D10 cyclic compounds and small molecular chains in ordinary silicone oil are prone to volatilize and escape under heating or vacuum conditions, resulting in pinholes, bubbles, or foggy defects in the coating. This series significantly reduces the content of these volatile impurities through special purification processes, ensuring the cleanliness of downstream processing from the source.


In semiconductor manufacturing, the coating and coating process on the surface of silicon wafers have extremely high requirements for material purity. Any trace volatiles escaping may affect lithography accuracy or the density of the film layer. In the production of optical fibers, the volatile content of the coating silicone oil directly affects the transmission loss and mechanical strength of the optical fibers. In the aviation electronics field, high-reliability insulating coatings and sealing materials also require low-volatile silicone oil as a basic component.


3. Main Application Domains


The product series low-volatile silicone oil LS can play a key role in the following high-end application fields, specifically:


1. Semiconductor and silicon wafer manufacturing. The product is suitable for coating and coating processes on the surface of silicon wafers. The low-volatile property helps ensure the cleanliness of the processing environment and reduces yield losses caused by volatile substance contamination.


2. Optical fiber production and coating protection. In the fiber drawing and coating processes, the low-volatile silicone oil used as the basic raw material or additive for the fiber coating can reduce bubble defects during coating curing, ensuring the transmission performance and long-term reliability of the optical fibers.


3. Aviation electronics and high-end electrical insulation. The product is suitable for insulating coatings and sealing protection of precision components in aviation electronics equipment. The low volatility and low cyclic compound content help ensure the long-term stability of the equipment in extreme temperature and vacuum environments.


4. Silicone rubber products with low volatility requirements. This product can be used as a basic raw material or modified component in formulations for liquid silicone rubber, organic silicone pressure-sensitive adhesives, etc., meeting the strict requirements for volatile content in medical, electronic, and food contact grade silicone rubber products.


4. Quality Assurance and Industry Chain Value


The product series low-volatile silicone oil LS implements strict process control over key indicators such as volatile content and residual cyclic compounds during production, ensuring consistency and reliability between batches. As the high-end manufacturing fields such as semiconductors, optical communications, and aerospace continue to develop towards higher precision and greater reliability, the demand for high-purity and low-volatile organic silicon base raw materials is steadily increasing. The product low-volatile silicone oil LS series, with its series coverage of methyl, vinyl, and hydrogen product lines, diversified viscosity specification options, and strict purity control standards, is becoming an important basic raw material option in the fields of high-end coatings, packaging, and insulation materials. It provides strong support for the domestic independent supply of high-purity organic silicon materials.
