Amorphous Styrene Block Copolymer
Description
Petadd VM-S12(A) is a multi-arm block copolymer obtained by hydrogenation of branched styrene-butadiene-styrene block copolymer. It acts as both a VI improver and an oil viscosity thickener for high quality lubricants. It contains a non-staining, TNPP free antioxidant system.
Application
- Use a viscosity modifier and oil viscosity thickener for quality lubricants.
- Provides excellent shear and oxidative stability.
- The amorphous composition means the material displays superior cold properties and helps reduce the demand for PPDs.
Storage and Handling
Store and handle in accordance with good chemical handling and hygiene practices. Consult the SDS for specific information.
