Electrical Contact Lubricants
High Performance Speciality Automotive Lubricants
BECHEM’s range of electrical contact greases are formulated with special low viscosity synthetic oil and organic polymer thickeners. These life lubricants protect contacting surfaces by ensuring high strength lubricating film that are compatible with engineering plastics and also possess excellent noise dampening properties.
Ability to regulate the flow of current while remaining inert to the surge, good anti-corrosion and anti-wear properties and high surface tension to avoid migration are some of the desired properties of good electrical contact greases. More importantly, it should be noiseless and provide a smooth operating experience to the user. The need is for a special lubricant that can withstand the flow of current and harsh operating conditions inside a switch with minimum presence for a very long time.
Applications where electrical contact greases are being used currently in the industry include ignition and micro switches, plug connectors, printed circuit boards, combination switch, mirror adjustment switches, wiper motors, starter and window regulator motors

Range of synthetic lubricants developed for electric contacting surfaces of varying currents that experience friction and temperature rise. Berulub FK Series are water resistant and protect contacting surface from friction and wear. The special range provides life lubrication for contacting surfaces as well as protection against dust impurities. With wide operating temperature range Berulub FK series can meet climatic challenges of extreme low/high temperatures and prevents spark formation on electric contact surfaces. Compatible with special metals, coated metals as well as polymeric materials such as PC, PMMA, ABS etc.
Applications: Recommended for electrical systems in vehicles and energy systems that experience resistive loads, inductive loads, switches and small gears. Also, suitable for all kinds of carbon-film potentiometers, relay switches, motor or generator commutators, variable condensers, high frequency sliding contacts. Possesses noise dampening ability. Please consult a BECHEM Application Engineer for selection of the suitable grade of ‘Berulit FK’ series for your application.

Reliability Through Speciality
Lubricant characteristics vital for the smooth functioning of critical automotive components include,
Wide service temperature range
Automotive vehicles need to operate effortlessly in sub zero environments as well hot sweltering conditions. Correspondingly, the lubricants used in various critical automotive components also need to perform in extreme temperatures
Material compatibility
At high temperatures, plastic composites tend to diffuse and lose their inherent characteristics by borrowing from or combining with ingredients of contacting surface or lubricating medium. Migration of the lubricant molecules inside the plastic composite result in the undesired affects of swelling and softening of plastic material
Electrical compatibility
Modern day automobiles contain host of electrical components such as motors, actuators and switches. These components also contain moving surfaces and need to be lubricated to avoid severe electric arc formation and jaded surfaces
Durability and corrosion protection
The lubricant has to form a protective film around the contacting surfaces and prevent corrosion and wear against the odds of water, dirt and varying loads.
Noise dampening ability
Undesirable squeaks and rattles caused by vibration in operational condition is a common problem faced by auto and component manufacturers in spite of good design. These squeaks can be muted by use of specialized automotive lubricants.
Life time lubrication
In many automotive applications intermittent lubrication is not possible, the lubricant will have to maintain its composition until lifetime of the component
Environmental compatibility
Lubricant should be devoid of heavy and toxic metals.
