In fields such as high-end lubricants, cosmetics, electronics, and aerospace, phenyl silicone oil is becoming the preferred material for more and more engineers due to its excellent thermal stability, superior refractive index adjustability, and low volatility characteristics. Today, Betely will introduce its range of phenyl silicone oil products in detail to assist you in precise selection and enhance product competitiveness.
About Betely
Betely specializes in the research, development, production, and sales of silicone rubber materials and organosilicon additives, committed to providing high-performance, high-stability organosilicon solutions to global customers. In the field of phenyl silicone oil, leveraging profound technical expertise and strict quality control, the company has developed a series of phenyl silicone oil products with outstanding performance and wide-ranging applications.
I. What is Phenyl Silicone Oil?
Phenyl silicone oil, also known as polyphenylsiloxane, is a type of specialty silicone oil modified by introducing phenyl groups into the siloxane main chain. Compared with conventional dimethyl silicone oil, phenyl silicone oil exhibits a higher refractive index, better heat resistance, and oxidation resistance, maintaining stable physical and chemical properties especially under extreme temperature conditions.
Betely's phenyl silicone oil products cover various specifications of viscosity, refractive index, and volatile content, widely used in cosmetic-grade fluids, industrial lubrication, high-temperature release agents, and other fields.
II. Betely Phenyl Silicone Oil Technical Parameters
The following are key indicators for some representative models:
Model | Appearance | Viscosity (25°C) | Volatile Content | Refractive Index | Flash Point | Odor |
CSGW-Y4501 | Colorless transparent | 120~150 mm²/s | ≤3.5% (250°C/4H) | 1.4920~1.5000 | ≥330°C | Odorless |
CSGW-Y4502 | Colorless transparent | 150~250 mm²/s | ≤5.0% (250°C/4H) | 1.4900~1.5000 | ≥310°C | Odorless |
CSGW-Y4504-2 | Colorless transparent | 360~440 mm²/s | ≤3.5% (250°C/4H) | ≥1.5000 | ≥330°C | Odorless |
CSGW-Y4510-1 | No impurities, no caking | 900~1100 mm²/s | ≤3.5% (250°C/4H) | 1.4880~1.4970 | ≥330°C | Odorless |
CSGW-Y4710-1 | Colorless transparent | 790~800 mm²/s | ≤5.0% (250°C/4H) | 1.4980~1.5050 | ≥310°C | Odorless |
The above products all meet the standards of no impurities and no caking, with a color index ≤20 Hazen, ensuring high purity and batch-to-batch stability.
III. Core Advantages and Application Scenarios
1. Excellent High and Low Temperature Resistance
Several Betely phenyl silicone oil products, such as CSGW-Y4501 and CSGW-Y4504-2, feature flash points ≥ 330°C and smoke points > 220°C, making them suitable for demanding conditions like high-temperature lubrication and heat oil carriers.
2. High Refractive Index and Transparency
The refractive index can reach up to 1.5350, suitable for optical coatings, transparent seals, and cosmetic formulations to enhance product gloss and spreadability.
3. Low Volatility, High Stability
Volatile content is controlled within 3.5% (250°C / 4H), ensuring consistent performance over long-term use. Suitable for applications with high cleanliness requirements such as electronic packaging and precision instrument lubrication.
4. Cosmetic-Grade Fluids
Models like CSGW-Y4731-2 (reference from context, though not in table) feature low viscosity, are odorless, and meet cosmetic-grade fluid requirements. They can serve as substitutes for phenyl trimethicone and are widely used in high-end personal care products such as skincare and color cosmetics.
