Slide 7: EXCEREX - the new generation processing aid
EXCEREXTM- the new generation processing aid “EXCEREXTM” is a high performance olefin oligomer. It was commercialized for the first time in the world in 2004 by using metallocene catalyst technology. EXCEREXTM has many advantages as follows: Ø Productivity improvement Ø Low process temperature Ø Dec
Slide 8: Narrow Molecular Weight Distribution, Narrow Composition Distribution
Narrow Molecular Weight Distribution Narrow Composition Distribution Relation of composition distribution and M.W. distribution Sharper elution temperature range means narrower composition distribution EXCEREXTM Olefin wax (Mv 4000, D 930 kg/m-3) (Mv 4000, D 930 kg/m-3)
