Molykote® 5 Silicone Compound is a high-performance insulating grease formulated with a blend of dimethyl and phenylmethyl silicone fluids and inert fillers. It provides excellent dielectric strength, thermal stability, and moisture resistance, making it ideal for sealing and protecting electrical connectors, insulators, and O-rings in demanding environments. The compound maintains its consistency across a wide temperature range and resists oxidation, water washout, and environmental degradation. Commonly used in power distribution systems, marine equipment, and industrial controls, it ensures long-term reliability of electrical insulation and mechanical sealing in both indoor and outdoor applications.

• Non-Conductive Property - Molykote® 5 exhibits superior electrical insulation with a dielectric strength exceeding 20 kV/mm. It effectively prevents current leakage, short circuits, and tracking under high-voltage conditions. The compound retains its non-conductive performance across temperatures from -40°C to 200°C, ensuring safety and reliability in both low and high voltage electrical systems where dielectric stability is critical.

  
  

• Water Repellency - The silicone-based matrix forms a hydrophobic surface film that repels water and moisture ingress. Laboratory immersion tests show less than 0.1% water absorption after 72 hours of exposure. This high water resistance prevents corrosion at electrical contact points and maintains sealing integrity in outdoor or submerged installations.

  
  

• Thermal Stability - Molykote® 5 provides consistent rheological and dielectric performance at elevated temperatures. With a specific heat of 1.541 J/g°C and thermal conductivity of 0.238 W/m·K at 30°C, the compound resists breakdown under sustained heat. It maintains its lubricating and sealing properties during continuous operation in environments reaching up to 200°C, reducing maintenance frequency and extending component life.

  
  

• Long-Lasting Durability - The material’s resistance to oxidation and chemical degradation ensures long-term service without hardening or evaporation. Aging simulations under 150°C for 1,000 hours show no significant change in consistency or dielectric strength. This durability allows Molykote® 5 to maintain stable insulation and sealing function for years in static or dynamic assemblies.

  
  

• Easy Application - The semi-flowable texture allows the compound to be easily applied by hand, brush, or automated dispensing. It spreads uniformly over complex geometries and thin gaps, forming an even protective layer without sagging or separation. This ensures complete coverage on irregular components and reduces application time during production or maintenance.

  
  

• Environmentally Responsible - Molykote® 5 contains no intentionally added PTFE or per- and polyfluoroalkyl substances (PFAS), meeting current environmental and safety standards. The formulation minimizes volatile emissions and complies with modern industrial sustainability requirements, offering a safer solution for power, marine, and automotive applications while reducing ecological impact.

• Power Distribution - Molykote® 5 is widely used in high-voltage switches, connectors, and O-ring seals in power distribution systems. It prevents arcing and surface tracking while providing reliable insulation under variable load conditions. Test data show a 30% reduction in contact resistance degradation after long-term exposure, enhancing operational stability and reducing outage risk.

  
  

• Marine Equipment - The compound protects exposed electrical and mechanical components in marine environments where humidity, salt spray, and temperature fluctuations are frequent. Its strong water repellency ensures insulation resistance retention above 10¹³ Ω·cm after salt fog exposure, supporting uninterrupted function of navigation and propulsion systems.

  
  

• Automotive Systems - In vehicle electrical assemblies such as ignition systems, battery connectors, and sensor seals, Molykote® 5 ensures dielectric stability under vibration and high heat. It maintains mechanical integrity under 200°C engine compartment conditions and prevents corrosion-related electrical faults, enhancing long-term reliability and reducing service intervals.

  
  

• Industrial Controls - The compound serves as an insulating and sealing medium for control panels, circuit breakers, and automation devices in manufacturing facilities. It protects terminals from condensation, dust, and oil vapor contamination, ensuring precise signal transmission and preventing system downtime. Field performance tests show a 25% improvement in insulation retention under cyclic humidity exposure.
