  • Publication number: 20230029135
    Abstract: The inventors have discovered hot melt adhesive compositions that can be formulated to have a high percentage of environmentally conscious components and still provide performance over a broad temperature range. The invention features a hot melt adhesive composition including from 5% by weight to 50% by weight of a styrene block copolymer, from 15% by weight to 75% by weight of a bio-based tackifying agent, and from 5% by weight to 40% by weight of an aliphatic plasticizer having a cyclo-aliphatic content of no greater than 1% by weight as tested by 1H-NMR Spectroscopy, wherein said hot melt adhesive composition has an environmentally conscious component content of at least 50% by weight.
