UltraLube multi-purpose lithium grease are biobased lubricants that are manufactured from renewable vegetable-base stocks which have a naturally higher viscosity index. This means that bio-based oil is likely to "thin down" at high temperatures providing reduced overall operating temperatures and a higher degree of lubrication-safety, especially in high speed applications. These UltraLube products are premium quality biobased products formulated from renewable, biodegradable USA-grown vegetable oils. These lubricants are designed to replace and mix with conventional petroleum products to help you and your customers use safer lubricants.
