Switches, connectors and slip rings transmit current and signals in increasingly precise, durable electrical equipment. Frequent insertion, switching, rotation, temperature cycling, fretting and oxidation can increase contact resistance, interrupt signals, cause sticking and noise, and lead to leakage-current failures. Specialty electrical greases combine wear and noise reduction, insulation protection, stable conduction, corrosion resistance and temperature capability. SEIVIO grades address the distinct requirements of switches, connectors and slip rings.
Pushbuttons, toggle and rocker switches, terminal connectors, waterproof joints and board-to-board connectors face frictional wear, metal-contact oxidation, aging of rubber and plastic parts and changing insertion forces. Conventional greases can evaporate, form carbon deposits, damage plastics or provide inadequate insulation. SEIVIO synthetic-base-oil products with functional additives emphasize compatibility, stable performance and lasting protection.
Swilub C199 Electrical Mating-Part Grease uses a PFPE/HCFC mixed base and PTFE lubricating components for electrical insertion and removal. Its operating range is -50~110°C, with short-term resistance to 240°C, suiting appliances, communications equipment and vehicle connectors. Compatibility with silicone rubber and engineering plastics avoids swelling, hardening and cracking and supports lifetime lubrication. It reduces and equalizes insertion resistance in board-to-board connectors, harness terminals, vehicle plugs and communications interfaces, limits fretting-related contact failures and suppresses terminal oxidation and rust, improving conductivity and service life.
Rublue S523 Silicone Rubber Grease serves high-voltage cable joints, sensor terminals, ignition coils and waterproof connectors. Lubrication, insulation, waterproofing and oxidation protection help prevent electrical leakage and moisture-related short circuits through temperature changes.
Rublue K021 O-Ring Grease combines PFPE base oil and ultrafine PTFE thickener for connector seals. EPDM compatibility, with volume change below ±5%, protects seals. It reduces insertion and assembly force and prevents tearing while maintaining barriers against dust and moisture. Applications include industrial waterproof connectors and sealed precision-instrument joints.
Rublue P303 Plastic and Rubber Grease uses PFPE base oil and inert antiwear additives for plastic/plastic and rubber/metal pairs. It avoids corrosion, swelling and embrittlement while reducing switching noise and friction. It serves low-load, high-frequency appliance pushbuttons, small toggle switches and precision microswitches, addressing sticking, poor return and noise.
Slip rings transfer current and signals during rotation in aerospace, radar, intelligent equipment, automation and precision instruments. Continuous rotation can cause contact fretting, resistance fluctuations and corrosion, especially at temperature extremes or high speeds. Lubricants therefore need stable electrical behavior, temperature resistance and wear protection.
SEIVIO's low-temperature specialty grease supports operation down to -70°C while providing wear resistance and adhesion. It maintains a film on metal contacts and stable contact resistance across temperature changes, limiting signal interruptions and current fluctuations. Applications include aerospace equipment, scientific probes, outdoor radar and wireless communications under severe outdoor and industrial conditions.
Electlub P785 Silver Conductive Grease serves precision slip rings with very low resistance requirements. It operates at -50~180°C, with short-term resistance to 200°C. Volume resistivity is 0.01-0.03 Ω·cm and typical contact resistance is below 0.08 mΩ. Its stable, uniform film protects gold- and silver-plated contacts, suppresses fretting corrosion and arc damage, and limits signal interference and current fluctuation during rotation. Applications include precision inspection, advanced communications and military-grade precision slip rings.
Eleclub B270 High-Speed Conductive Grease serves integrated slip-ring and bearing units at high rotational speeds. It provides high-speed, shear and wear resistance, with a speed factor of 1.0×10, and supports high loads and speeds. Antistatic and discharge-protection properties help avoid voltage-discharge damage in high-speed automation equipment and intelligent-robot slip rings.
The range covers routine service, low and high temperatures, high speeds, precision conduction and waterproof sealing. Material compatibility, stable electrical behavior and lasting lubrication address wear, oxidation, leakage, unstable signals and sticking in consumer electronics, automation, vehicle electronics and aerospace research equipment.
