In modern industrial production and fine chemical manufacturing, polydimethylsiloxane (PDMS) has become an indispensable basic raw material due to its unique molecular structure and excellent physicochemical properties. Jiujiang Deep-Sea Technology's PDMS-350CS methyl silicone oil, as a typical medium-viscosity linear polymeric silicone, demonstrates core competitive advantages in multiple industries such as personal care, automotive detailing, industrial lubrication, and electronics, thanks to its excellent thermal stability, chemical inertness, and surface activity.
I. Core Chemical Characteristics and Technical Parameters
Jiujiang Deep Sea Technology's PDMS-350CS silicone oil has a Si-O-Si main chain with methyl groups attached to the side chains. This helical structure results in extremely weak intermolecular forces, with the methyl groups aligning outwards and rotating freely, thus endowing the product with a series of excellent physical properties.
Appearance: Completely transparent fluid, colorless, odorless, tasteless, and non-toxic.
Flash Point (Open Cup °C): Greater than 326 °C, providing extremely high fire safety and suitable for high-temperature operating environments.
Viscosity Temperature Coefficient: 0.60. This means the product has low sensitivity to temperature changes and maintains stable dynamic viscosity even under significant ambient temperature differences, ensuring consistent damping or lubrication effects.
Solubility Parameter: 7.4. Surface Energy: Possesses extremely low surface tension, excellent film-forming properties, and spreads easily on various substrate surfaces.
II. Wide range of application scenarios
Textile lubricant: As a smoothing agent for sewing threads, its thermal stability and low viscosity-temperature coefficient prevent thread breakage and static electricity during high-speed sewing.
Defoaming system: Due to its insolubility in water and most animal and vegetable oils, it achieves highly efficient defoaming in the petroleum, chemical, and paper industries with only a very low addition ratio.
Specialty coatings: Used for waterproofing and mildew prevention on glass and ceramic surfaces, and to improve the protective performance of insulating devices.
Elastomer lubricant: As an internal or external lubricant for plastic and rubber products, it improves processing fluidity.
