Silicone grease is a semi-solid lubricant made from silicone oil as a base oil, with thickeners, functional fillers, and special additives. Its main component, polydimethylsiloxane (PDMS), imparts excellent thermal stability, chemical inertness, and electrical insulation to silicone grease.
Silicone grease typically has the following characteristics:
High and Low Temperature Resistance: Remains stable in temperatures ranging from -50°C to 200°C (or even higher).
Waterproof and Sealing: Effectively prevents the intrusion of moisture, dust, and other contaminants.
Electrical Insulation: Suitable for insulating and protecting electronic components.
Chemical Inertness: Compatible with a variety of materials, including metals, plastics, and rubber, and is not susceptible to chemical reactions.
Key Application Areas
Electronics and Electrical Industry:
Silicone grease is widely used for insulation and lubrication of electronic connectors, switches, relays, and other components. Its high dielectric strength and arc resistance prevent short circuits and oxidation, extending device life. Silicone grease also plays a crucial role in sealing LED heat dissipation interfaces, circuit board protection, and high-frequency connectors.
Automotive Industry:
Automotive sensors, brake systems, spark plug seals, and electric vehicle battery packs must withstand high temperatures, vibration, and chemical corrosion. Silicone grease provides long-term, stable lubrication and sealing, enhancing safety and reliability.
Medical Devices:
Since silicone grease is non-toxic, odorless, and complies with biocompatibility standards (such as ISO 10993), it is used for lubrication and sealing of medical devices such as syringe plungers, respiratory valves, and surgical instruments.
Industrial Manufacturing:
Valves, pumps, seals, and rubber components operating in high-temperature and high-pressure environments often use silicone grease to reduce friction and wear. Silicone grease is also used to maintain laboratory instruments, optical equipment, and plastic gears.
Silicone grease produced in China boasts exceptional performance. Based on polydimethylsiloxane (PDMS), it possesses excellent thermal stability, chemical inertness, and electrical insulation properties. Suitable for use in extreme high and low temperature environments, it offers multiple functions, including waterproof sealing, dustproofing, and electrical protection. Its applications span key sectors such as electronics, automotive, medical devices, and industrial manufacturing, effectively extending equipment life and improving safety and reliability, making it an ideal lubricant and sealing material across various industries.
