Silicone Fluid - A Versatile Material With Many Uses

Silicone fluid is a versatile material used in many industrial, military and consumer applications.silicone fluid Its unique properties and wide range of uses have spawned a multitude of different varieties, each designed for specific functions and environments. From the conventional PDMS oils to highly specialized amino-modified and fluoro-modified formulations, each silicone oil has its own unique characteristics and applications.

Unlike organic hydrocarbon fluids that have a carbon-to-carbon molecular structure, silicone fluids are based on a backbone of silicon-oxygen linkages similar to the Si-O links found in high-temperature inorganic materials like quartz and glass. This gives silicones a higher resistance to temperature extremes, oxidation, shear stresses and chemicals. The chemical structure of the silicone fluids also imparts them with a number of other desirable properties.

The low viscosity of pure silicone fluids (typically under 5 centistokes) enables them to be easily spread, making them an excellent base fluid for most formulating applications. The low surface tension of pure silicones and their volatile nature also contribute to their ability to evaporate quickly, leaving a thin protective film on surfaces. Silicones also have an unusually high compressibility and shear stability that makes them superior to most other lubricants.

Clearco offers a variety of silicone oils and fluids to meet various performance requirements. These include lubricants, dampeners and release agents. Silicones are characterized by their biocompatibility and non-toxicity, which make them an ideal ingredient for medical devices, prosthetics and cosmetics. They are also non-flammable and resistant to abrasion, corrosion and UV radiation. These properties, combined with their wide-ranging environmental stability and chemical resistance, have made them a favorite choice for dielectric, hydraulic, power transmission and heat transfer fluids. They are frequently incorporated into plastics and rubbers as processing additives, in coatings for leveling, flow and surface control, and into process streams as antifoaming agents.

In addition to its lubricating properties, silicones are also known for their excellent thermal stability, low shear strength and a wide operating temperature range. They also have low volatility and vapor pressure, making them environmentally safe for use in sensitive environments.

Different types of silicone fluids are available to address specific needs. Conventional PDMS fluids, for example, have a linear molecular structure and are often used as dielectric fluids. Their thermal stability enables them to withstand temperatures from below freezing up to over 200 degrees Celsius.

Electrical grade silicone fluids, such as Clearco STO-50 Silicone Transformer Oil, are formulated to meet specific dielectric and thermal conductivity specifications. They are often used in capacitors, specialty transformers and in systems where heat transfer properties are as important as dielectric behavior. Food grade silicones, such as Clearco PSF-350cSt, are NSF/USDA registered H1 lubricants for incidental contact with food. They are often used as lubricants and release agents for medical devices and in pharmaceuticals. They are also incorporated into luer taper, the standardized fitting system that makes leak-free connections between syringe tips and needles. This is particularly useful in Needle Exchange Programmes, a social policy based on harm reduction where injecting drug users can get clean syringes and injection equipment at little or no cost.
