Bluesil 47V350 is a food-approved silicone fluid widely used as an antifoam and lubricant in food processing industries.It also has excellent stability, lubricity, and thermal resistance. It is widely used as a release agent, heat transfer medium, cosmetic ingredient, and coating additive, offering reliable performance across industrial and personal care applications.

• High-Temperature Resistance - Bluesil 47V350 maintains stable viscosity at 150°C and maintains lubrication properties even at 250°C for short periods. Its flash point is above 300°C, making it less susceptible to volatilization or combustion in high-temperature environments, ensuring safety and reliability.

  
  

• Viscosity Stability - With a viscosity of 350 mm²/s at 25°C, its viscosity varies minimally with temperature. Its viscosity index is significantly higher than that of conventional lubricants, ensuring consistent lubrication thickness in environments with alternating high and low temperatures. Professional testing shows that viscosity variation does not exceed ±10% within the temperature range of -40°C to +200°C.

  
  

• Thermal Conductivity - Bluesil 47V350 has a thermal conductivity of approximately 0.13 W/m·K, only one-quarter that of water, significantly lower than water. Its specific heat capacity is approximately one-third that of water, at ~1.5 kJ/kg·K. During use, it effectively reduces rapid heat transfer, providing insulation and temperature uniformity.

  
  

• Chemical Stability - This silicone oil is inert to most acids and bases at room temperature and has good compatibility with metals such as aluminum and stainless steel. Experiments have shown that its physical properties remain largely unchanged after 24 hours of contact with 10% NaOH or 10% H₂SO₄.

  
  

• Low Surface Tension - Bluesil 47V350 has a surface tension of approximately 21 mN/m (25°C), significantly lower than the 72 mN/m of water. This low surface tension provides excellent wetting and spreading properties, enabling it to quickly form a uniform film on solid surfaces.

• Mold Release - In the production of rubber, plastic, and other products, molds often require release agents to prevent product adhesion. Bluesil 47V350's low surface tension and chemical inertness enable it to form a stable release layer on mold surfaces. Field tests have shown that after application, it can withstand over 200 consecutive mold releases while maintaining its stability, reducing mold cleaning and downtime.

  
  

• Home Care - In home care products, Bluesil 47V350 is often used as a polish and protective agent. With a refractive index of 1.403, it imparts a high gloss and provides a water-repellent barrier. When used on furniture or stone, it creates a long-lasting shine and reduces stain penetration.

  
  

• Electrical and Electronics - In the production and operation of electrical and electronic equipment, Bluesil 47V350 is used as an insulating fluid and protective coating. Its high volume resistivity of 10⁴ Ω·cm effectively isolates against leakage and short circuit risks. In aging tests in a humid environment, treated circuit boards were shown to withstand continuous operation for over 1,000 hours at 85°C/85% humidity without failure.

  
  

• Personal Care - This silicone fluid is widely used as a conditioning agent and coating component in cosmetics and personal care products. Its low surface tension and excellent spreading properties enable skincare and haircare products to form a uniform film on the skin or hair. Experimental data shows that adding 1% Bluesil 47V350 to an emulsion improves coating uniformity by over 30%, resulting in an improved skin feel.

  
  

• Automotive - In the automotive industry, this product is used for high-temperature lubrication and protection of engines and components. Its flash point exceeds 300°C, ensuring stability in the high-temperature engine compartment environment. Compared to mineral lubricants, which require replacement every 100 hours at high temperatures, Bluesil 47V350 can extend its service life to over 300 hours under the same conditions, significantly reducing maintenance frequency and improving vehicle reliability.
