Description
high base number synthetic calcium sulfonate is one of the series of petroleum additives developed by us through technical cooperation with Sinopec Research Institute of Petroleum Processing. It’s mainly made from heavy alkyl benzene sulfonate by means of neutralization and high-base reaction. As a major metal detergent, this product has excellent acid neutralization capacity, good anti-rust property and high-temperature detergency, so it is widely used for different engine oil.
- Excellent high-temperature detergency and acid neutralization capacity
- Excellent water separation property and anti-foam performance
- Low turbidity and good compatibility with various kinds of base oils
- Good compatible with other additives
