Hydrocarbon tackifiers for propylene based elastomers

  1. 1. 1 April 29, 2014 2014 Adhesive and Sealant Conference Orlando, FL Ranjan Tripathy Senior Research Chemist Hydrocarbon tackifiers for propylene-based elastomers
  2. 2. 2 ExxonMobil Chemical is committed to adhesives industry leadership • Investing in the world’s largest hydrogenated hydrocarbon resin unit to supply customers needs for Escorez™ tackifying resins • Innovating with new products like Vistamaxx™ performance polymers made with proprietary metallocene catalysts • Leveraging our expertise in polymers and tackifying resins to optimize product synergies 2 Propylene Crystallinity Ethylene Crystallinity PE MolecularWeight Vistalon EPDM rubber Exact Plastomers PP Vistamaxx performance polymers Lower Crystallinity/Density Vistamaxx polymers In Adhesives Achieve™ Exceed™ Enable™ mPE VistamaxxTM polymers enable unique approach for formulating HMAs
  3. 3. 3 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 0 400 800 1,200 1,600 2,000 1996 2000 2004 2008 2012 2016 2020 kt Hot Melt Industry Growth (Adhesive Volumes) Conventional C5/C9 or RE + HEVA, APAO Premium H2 resin + mPO, SBC, HEVA HMA Growth ‘13-’20: 4% 2% Source: ExxonMobil estimates and publicly available data
