Towards the modern automotive industry: Adhesive innovations with styrenic thermoplastic elastomers in automobile manufacturing, hot melt adhesives have numerous purposes, such as applications in the trunk, roof linings, seat assembly, filter manufacturing, emblems, trim and assembly bonding. The trunks of modern cars, especially trucks with large storage space, are complex. Individual elements, such as the trunk floor, rear seat backs, rear covers, etc., have been produced for several years with dispersion based adhesive systems, with a growing trend of polyurethane reactive (PUR) systems. It is worth noting that to ensure the safety of the manufacturer/environment/end user, the adhesives must have low emission properties. The use of adhesives for textile materials, foam elements and lightweight components, and combinations of these materials, allows structurally simple solutions. However, adhesives and bonded elements must meet the requirements resulting from the demanding temperature changes in the trunk area.
