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 enhance adhesion

and heat resistance

• Low viscosity Vistamaxx polymers

enable high polymer loading

• Higher polymer level favors higher

efficacy additives

• Tackifying resin selection contributes

to final properties even at lower load

• Adhesion

• Heat resistance

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
