Polydimethyl Siloxane
Product Description
Distinguished by its superior attributes compared to methyl silicone oil, our product offers enhanced low-temperature resistance, superior electrical insulation, and a longer ethyl carbon chain, resulting in superior compatibility with organic solvents. Operating within a temperature range of -60°C to 150°C, it exhibits minimal temperature-viscosity coefficient, alongside outstanding lubricating and dielectric performance. Characterized by low volatility, low surface tension, non-toxicity, non-corrosiveness, and anti-aging properties, it can be blended to various viscosities to suit specific application requirements.
