TBN400 Calcium Sulfonate - Premium Detergents in Engine Oil
Ultra-High Performance Detergents in Engine Oil & Grease Applications
It is a super-alkaline calcium sulfonate detergent. It is produced using long-chain (C20~24) linear alkylbenzene sulfonic acid. It has excellent high-temperature detergency, excellent acid neutralization performance and anti-rust performance. It also has good hydrolysis safety and good anti-gel ability. It is widely used in the preparation of worm turbocharged diesel engine oil, marine cylinder oil, crankcase lubricating oil and high-grade grease.
Product Introduction
This super-alkaline calcium sulfonate represents the most advanced detergents in engine oil technology (TBN 400). Produced with long-chain linear alkylbenzene sulfonic acid, it delivers exceptional high-temperature detergency, acid neutralization, and rust protection for both engine oils and high-performance greases.
Advantages of Our Detergents in Engine Oil
