Key Characteristics of BL-250 Phenyl Silicone Fluid
BL-250 is a high-performance straight-chained Polyphenylmethylsiloxane, where part of the methyl groups are replaced by phenyl groups— a modification that enhances its overall performance compared to standard dimethyl silicone fluid. As a versatile phenyl silicone fluid, BL-250 delivers exceptional stability in extreme high and low temperature environments (-40 ~ 300°C), making it a top choice for industrial applications requiring reliable performance under harsh conditions.
Compared to traditional dimethyl silicone fluids, BL-250 Phenyl Silicone Fluid offers superior lubricity, mold release properties, and electrical insulation performance— critical for industrial machinery, electronics, and precision instruments. It features a small temperature-viscosity coefficient and low volatility (≤2.5% at 250°C for 4 hours), ensuring consistent performance even during long-term use at high temperatures. Additionally, it boasts a high compression rate and surface tension, along with excellent miscibility with other organic resins, expanding its versatility across various industries. Its unique UV-resistant properties also make it suitable for outdoor or light-exposed applications.
- Superior Heat Resistance: Maintains stable performance in temperatures ranging from -40°C to 300°C, with high thermal stability and oxidation resistance even at 250°C and above.
- High Flash Points: Flash point of ≥274°C across all viscosity grades ensures safe use in high-temperature industrial environments.
- Low Volatility: Volatility ≤2.5% at 250°C for 4 hours, reducing fluid loss and maintaining consistent performance over time.
- Excellent Compatibility: Good miscibility with other organic resins, making it easy to integrate into existing production processes.
- Strong Electrical Insulation: Ideal for electronic applications that require reliable insulation performance, such as capacitors and transformers.
- Multi-Viscosity Options: Available in 5 viscosity grades (75, 100, 150, 1000, 30000 mm²/s) to meet diverse industrial application needs.
