PUCONS Polymethylphenylsiloxane High-Temp Thermal Fluid 25-500 cSt

Product Properties

Product Introduction

Polymethylphenylphenylsiloxane (25–500 cSt) is a methyl-phenyl co-modified silicone polymer combining the flexibility of polydimethylsiloxane (PDMS) with the thermal resistance and optical properties of phenylsiloxanes. Its unique molecular structure (phenyl substituents on the Si-O backbone) significantly enhances oxidation resistance and high-temperature stability while maintaining low-temperature flexibility. Solvent-free and meeting electronic-grade purity standards, it is suitable for precision industrial applications.

Enhanced Properties

Enhanced Thermal & Optical Performance​
The phenyl groups elevate the ​glass transition temperature (Tg)​​ to approximately ​**–80°C​ (vs. –127°C for PDMS), significantly broadening the operational temperature range (–50°C to 250°C). Concurrently, the refractive index increases to ​1.46–1.48**​ (vs. 1.40 for PDMS), making it ideal for optical applications requiring transparency and light management.

​Superior Viscoelastic Behavior​
Low-molecular-weight variants (e.g., 25–100 cSt) exhibit ​thermorheological simplicity: viscosity-temperature dependence follows a single activation energy, enabling predictable performance in coatings and lubricants

Higher viscosities (200–500 cSt) demonstrate ​reduced chain entanglement, resulting in lower shear-thinning and enhanced flow stability under stress

Application Scenarios

1. High-Temperature Lubricants​
   Automotive and aerospace systems requiring stability >200°C
2. ​Optical Encapsulants​
   LED and display components demanding high refractive index and UV resistance
3. ​Polymer Modification​
   Additive for enhancing thermal stability of plastics (e.g., PMMA, PC)
4. ​Cosmetics & Personal Care​
   High-end foundations and sunscreens leveraging its non-greasy texture and SPF-boosting properties
