Technology (UPN: 23)
|Making adhesives surfaces reversible|
|Organisation Region||European Union|
|Overview||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.|
If you have parts which are bonded and need to be repaired or replaced, or particularly for the disassembly of expensive parts/materials, allowing the reuse of the raw materials, then the proposed technology has a huge potential. The TEMs are placed on the surface in a primer/cleaner trapping the TEM in their dormant state, till the need to activate for debonding.
Key features of the proposed technology are the following:
The proposed technology has been demonstrated to work for the disassembly of parts/materials from different surfaces such as glass, aluminum, metals, composites, paper, golf heads etc…
Opportunities: e.g. Maintenance and dismantling operations (e.g. automotive industry for end of vehicle life dismantling, to remove car windscreens), and many other such as shoes, wall paper, floor tiles etc.
Glazing removal from vehicles, Boats maintenance and dismantling operations, Trains maintenance and dismantling operations, Aeroplanes maintenance and dismantling operations
No technology is in the market which covers most adhesives. The low cost of placing microspheres in at manufacturing is cents. The trigger energy need to activate the system is in most cases purchased by others. e.g. If the glazing bonded in a vehicle needs replacing then the energy need to trigger the system would be purchased by the repairer or garage. So low cost to the manufacture, but has the benefits to the vehicle customer, insurers, and at the end of life (ELV).
