High Performance Speciality Lubricants

BECHEM’s automotive range have proved to be reliable performance enhancers for the diverse and critical requirements of the automotive industry.

Lubricant characteristics vital for the smooth functioning of critical automotive components include,

  • Durability and corrosion protection
  • Noise dampening ability
  • Life time lubrication
  • Environmental compatibility
  • Wide service temperature range
  • Material compatibility
  • Electrical compatibility

These critical requirements can be met only with high performance specialty lubricants. BECHEM works along with renowned auto and component manufacturers across the globe in developing intelligent specialty lubricants that suit their applications seamlessly whilst also ensuring short product development durations.

Use of advanced plastics and leather trims in vehicle interiors increase the likelihood of extended contact between plastics, metal and leather linings. Undesirable noise is a possible outcome.

BECHEM’s range of electric 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.

BECHEM’s range of greases for automotive chassis and brake systems possess good stability, superior load bearing capabilities and ability to withstand extreme temperatures.

BECHEM’s range of Anti-Friction coatings are developed with combination of high quality solid lubricants, organic/inorganic binding agents, solvents and high performance additives. These performance coatings from BECHEM have provided excellent results to customers.


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.


Greases are made by mixing a solid material, called a thickener, with a base oil and property enhancing additives; but it’s the oil that forms the lubrication film. For better understanding, grease thickener can be thought of as a sponge saturated with oil. Moving parts squeeze the oil out of the sponge like thickener for forming the lubrication film. Typically, the base oil constitutes the largest proportion of grease weight at about 80-90%, followed by thickener at 10 to 20% and additives under 10%.

Dropping point of a lubricating grease is an indicator of the heat resistance of the grease. and is the temperature at which the grease is no more a thickened lubricating medium. The dropping point indicates the upper temperature limit at which a grease retains its structure, not the maximum temperature at which a grease may be used.

Few greases have the ability to regain their original structure after cooling down from the dropping point.

The most important feature of a grease is its consistency. A grease that is too stiff may not get pumped into areas requiring lubrication. While a grease that is too fluid may leak out. Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil. A grease consistency is its resistance to deformation by an applied force.

The measure of consistency is called penetration. Penetration depends on whether the consistency has been altered by working. Standard test procedures established by American Society for Testing and Materials International (ASTM) and accepted by industry are ASTM D 217 and D 1403, measure penetration of unworked and worked greases.

The NLGI has established consistency numbers ranging from 000 to 6, corresponding to specified ranges of penetration distance of the standard cone into the test grease. Table below lists the NLGI grease classifications along with a description of the consistency of each classification.

Viscosity: It is a measure of resistance to flow of a lubricating oil.

Viscosity index: It is defined as rate of change of viscosity with respect to temperature.


  • It is the most important property which determines the performance of lubricating oils under the influence of temperature
  • A lubricating oil should have sufficient viscosity to retain a lubricating film on the surface
  • On machine part moving at slow speeds under high pressures, a high viscous oil should be used as it better resists being squeezed out from between the rubbing parts.  Light oils can be used for lower pressures and high speeds.
  • It is not possible to maintain a liquid oil film between two moving or sliding surfaces if the viscosity is too low and hence excessive wear will occur.

The pour point of an oil is the minimum temperature at which the oil turns into semi solid and almost losses its flow characteristic. At low temperatures, the viscosity of the oil will be very high, causing the oil to resist flow. This is important in equipment that operates in a cold environment or handles cold fluids.
