NGM-Ether Type Shape Memory Polymer
NGM-Ether type shape memory polymers are plastics that have a shape memory effect, that is, they can apparently “remember” their previous outer shape despite a strong reshaping in the meantime. Shape memory polymers are the subject of intensive research. Their first commercial use is in medical technology, where metallic shape-memory materials already play a role, but can also have biological uses. A fascinating area where shape memory polymers impact is quite significant today is photonics. By being able to change their shape, shape memory polymers enable the production of functional and attractive photonic gratings. Recently, this technology has expanded for applications in orthopedic surgery. In addition, NGM-Ether type shape memory polymers are now used in various ophthalmic devices including punctum plugs, glaucoma shunts, and intraocular lenses. Other potential applications are self-repairing components, such as automobile fenders, in which indentations are repaired using temperature. After an undesirable deformation, such as a dent in the fender, these materials "remember" their original shape.
