Dispersant and Non-dispersant Comb Polymers - Building Blocks in Your Portfolio for Driveline Fuel Economy

摘要

(1) Reducing fleet average CO_2 emissions is our joint global challenge. (2) Comb polymers provide the essential tools for fuel economy. (3) ATF application: 1. Combs enable formulating balanced (high VI) ATF. 2. 1.2% NEDC fuel economy at 300{EUR} savi ngs in the value chain. 3. Even 0.5% fuel economy in demanding JC08 cycle. 4. Comb-based transmissions fluids introduced at global OEMs. 5. Dispersant comb provides high μ wet clutch performance. (4) MTF & axle application: 1. Combs boost 75W-xx gear oil viscometrics. 2. 0.5% FZG efficiency advantage using (experimental) comb polymer. 3. Dispersant comb shows improved dispersancy and pitting life-time.
