<p>Hot melt adhesives which include at least 5 % of a thermoplastic elastomer block copolymer having a Vicat softening temperature of at least 60 °C and a melting point of at least 100 °C, have improved thermal resistance of properties and can be applied with conventional hot melt application equipment at temperatures of between about 149 °C and about 204 °C. The adhesives are particularly suited to use in above-the-belt locations in automobile interiors and in furniture bonding. Especially suitable thermoplastic elastomers are polyether-polyester and polyether-polyamide segmented polymers with melting points above 149 °C. Hot melt adhesives based on these thermoplastic elastomers can be formulated to provide a range of properties including pressure sensitive properties and contact adhesive properties.</p> |
