Exceptional thermal stability up to 250 °C, maintaining viscosity and integrity under prolonged high-temperature exposure.
Outstanding oxidative resistance due to phenyl group incorporation, minimizing degradation in air-rich or catalytic environments.
Broad compatibility with organic solvents, resins, and elastomers—ideal for formulation integration without phase separation.
Low volatility and negligible vapor pressure at room temperature, supporting safe handling and reduced evaporative loss.
Tailored phenyl-to-methyl ratio providing balanced flexibility, refractive index (~1.53), and UV transparency for optical-grade uses.
High-performance release agents for silicone rubber and composite molding (e.g., aerospace RTM, automotive LCM).
Base fluid in thermally stable dielectric fluids for high-voltage transformers and electronic potting compounds.
Viscosity modifier and stress-relief additive in high-temp adhesives, sealants, and encapsulants.
Carrier medium for specialty pigments and UV-curable additives in premium coatings and inks.
Component in optical gels and lens bonding formulations requiring long-term clarity and refractive index matching.
