|23||Making adhesives surfaces reversible
Thermo-expandable microspheres (TEMs), which consist of an outer shell of copolymer thermoplastic resin encapsulating a liquid hydrocarbon, when the heat trigger is applied at command the microspheres expand to over 100 times their volume, acting as a pressure activator to cleanly break the bond at the interface, and the cohesive structure. A key part of the patented technology is the functionalization of the TEMs surfaces, e.i. a conducting material is applied onto the polymeric shells of the microspheres. This additional layer enables quicker ways to get the heat to the TEM surface without damaging the material itself.
The proposed technology consists of self-adhesive compostable materials from renewable resources. All materials are coated with EN13432 certified permanent adhesive.
