Hydrogenated resins and metallocene
polyolefins (mPO) drive market growth
• HMA demand growing at 4%
• Conventional HMA steady growth
• Wide market appeal
• Proven fit for use
• Premium packaging and nonwovens
rely on hydrogenated (H2) resin
• H2 resin and mPO drive growth
through value
• Improved stability
• Low color and odor
• Reduced usage

Preferred tackifiers for HMA having Vistamaxx™
performance polymer for packaging
• Moderate softening point and aromaticity
enhance adhesion when combined with
Vistamaxx polymers
• Liquid and polar tackifiers have limited
compatibility with Vistamaxx polymers
• Composition of preferred tackifiers for
Vistamaxx polymers
• Improves adhesion
• Improves heat resistance
