• High viscosity index: ensures that the lubricant remains effective at high temperatures by maintaining the thickness of the oil film.
• High flashpoint: considerably reduces the risks of fire in the event of a lubricant leak.
• Reduction in the quantities of the product lost through evaporation: meaning savings on the amount of money spent on lubricants.
• Low pour point and viscosity levels that remain low at low temperatures: ensuring excellent lubrication for cold starts.
• Guaranteed high levels of biodegradability and very low to zero toxicity in accordance with precise OECD criteria.
The benefits offered by biolubricants give them an edge over the conventional lubricants. The major salient features of the biobased lubricants are as follows:
• Excellent lubricity: The lubricity of the biobased lubricants is about 2 to 4 times their petroleum based corresponding lubricants. This reflects in the reduced mechanical losses and energy saving in the range from 5% to 15% of the equipment operation. • Higher viscosity index: The viscosity does not vary with temperature as much as the petroleum based lubricants. This makes bio-lubricants suitable for high temperature applications, typically 250°C or above.
• Lower volatility and high flash/ fire points: Biolubricants have a very good record in applications like grinding, where there is a known fire hazard. This also helps in oil mist reduction and hence the inhalation of the oil mist or vapours. The use is also safe due to higher flash points.
• Better skin compatibility and less dermatological problems.
• Biodegradability and non water polluting characteristic reduces the costs of disposal in addition to making them eco friendly.
