  1. 1. Investigation of new hot melt adhesives with plasticisers based on renewable resources : Investigating the use of sustainable plasticisers in hot melt adhesives

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Shadi Feyzabi; [2023]
    Keywords : Hot melt adhesives; renewable; mineral oil; vegetable oil; rheology; viscosity; loop tack; adhesive strength; Smältlim; förnybar; mineralolja; vegetabilisk olja; reologi; viskositet; loop tack; vidhäftningsstyrka;

    Abstract : Hot melt adhesives (HMA) are a class of adhesives that, unlike solvent-or waterborne counterparts, do not contain organic solvents or other carriers, and are produced and subsequently applied in a molten state. The main components of HMA are polymers, tackifying resins, and a plasticiser. READ MORE
