Shin-Etsu G-501 Low-Noise Silicone Grease for Plastic Parts
G-501 is a silicone grease developed by Shin-Etsu for lubrication of plastic components and blower bearings where both lubrication and noise reduction are required. It has a white to pale-yellow appearance and provides good lubricity on plastics while being less likely to cause cracking of plastic materials. The product provides good lubrication performance on common engineering plastics such as PC, POM and ABS, making it suitable for plastic gears, sliding parts, rotating mechanisms and blower-bearing applications involving plastic components. Its service temperature range is -50°C to 150°C, supporting both low-temperature starting and elevated-temperature operation.
Product Details
Product Features
Good Plastic Lubrication: Provides excellent lubrication on engineering plastics such as PC, POM and ABS.
Low-Noise Performance: Suitable for blower bearings and plastic sliding components where reduced operating noise is required.
Reduced Risk of Plastic Cracking: Designed to be less likely to cause cracking of plastic materials compared with unsuitable lubricants.
Good Low-Temperature Performance: Maintains relatively low starting and running torque at -50°C for smoother operation in cold environments.
Wide Service Temperature Range: Suitable for use from -50°C to 150°C.
Low Volatility: Volatile content is only 0.1% after 24 hours at 150°C, helping reduce grease loss at elevated temperatures.
Controlled Low-Molecular-Weight Siloxanes: ΣD3-D10 content is ≤100 ppm for applications requiring controlled low-molecular-weight siloxane levels.
Product Applications
Blower Bearings: Suitable for lubrication and noise reduction in blower and fan bearings.
Plastic Gears: Suitable for gears made from PC, POM, ABS and similar plastics.
Plastic Sliding Parts: Suitable for guides, sliders, linkages and other plastic-to-plastic or plastic-to-metal sliding interfaces.
Home Appliances and Small Motors: Can be used in fans, motors and household appliances containing plastic mechanical components.
Precision Mechanisms: Suitable for mechanisms requiring low noise, low friction and good compatibility with plastic materials.
