Licocene® for Adhesives in Carpets in the Automotive Industry


textiles such as carpets are increasingly used in the automotive industry in combination with adhesives previously synthetic latex based adhesives were used for this purpose however this material mix completely rules out later recycling of the textile components because latex and plastic can no longer be separated one remedy would be to use an adhesive based on the same plastics as the textiles so far however these hot melt adhesives have proved unsatisfactory as regards the decisive properties of flowability melting point and hardness the reason for this is the conventional manufacturing process these hot melt adhesives are based on simple molecules with double bonds known as olefins the aim is to flip over these double bonds such that the individual building blocks attach to each other and form long molecule chains known as polymers the industrial processes generally used for this purpose employ a catalyst molecule with a metal atom at its center where olefins are linked together the resulting polymer chains however have a random arrangement of molecules their teeth points sometimes in one and sometimes in the other direction the desired adhesive properties cannot be precisely obtained for like Essene basic polymers for hot melt adhesives Clariant has developed an innovative metallocene catalyst with a special structure that can precisely control the polymerization it forces the monomers to pass the catalyst in a very specific direction this allows the property profile of the adhesive to be adjusted very accurately to meet the respective requirements the latex adhesive is no longer necessary and recycling is no longer a problem you
