SIP (Styrene Isoprene Polymer)

Lubrizol offers a range of Styrene Isoprene Polymer (SIP) viscosity modifiers for use in crankcase and industrial applications. Available in both liquid and solid forms, SIPs offer superior thickening efficiency and improved low temperature performance while minimizing deposits and soot-related thickening in engine oils. In industrial applications, SIPs are efficient thickeners with superior low temperature flowability and provide excellent fuel efficiency and water wash-out benefits (for grease applications). SIPs are available in a choice of shear stabilities to meet customer performance and marketing needs.
