ExpertShape, memory shape polymer. Functional principle of shape memory polymers The principle is based on the change of shape of a material due to temperature. To do this, the polymer is “programmed” in a first step. It is molded into an “initial” shape, then mechanically deformed under heat (T > Tg) until the desired secondary shape is obtained. Then, while maintaining the force on the material, it is cooled, storing mechanical stresses. In the next step, the material is returned to its original shape on demand by heating. In this way, it changes from a glassy to a rubbery state, releasing the stresses stored during deformation.

PolymerExpert has innovated in the orthopedic field with the development of ExpertBone, a single-phase acrylic bone cement designed to enhance the surgical experience and patient outcomes. Unlike traditional acrylic cements, ExpertBone is pre-mixed in a cartridge, except for the activator, which is added just prior to injection. This approach eliminates the complex and potentially hazardous mixing steps typically encountered with conventional cements. The formulation creates consistent viscosity and optimal diffusion into bone tissue, reducing variability in surgery outcomes. Made primarily from polymethyl methacrylate (PMMA), ExpertBone integrates radio-opacifying fillers like barium sulfate or zirconium dioxide for improved visualization. Additionally, it mitigates the risks associated with handling toxic monomers by foreclosing manual mixing. This innovation signifies a major advancement in joint prosthesis surgeries, offering surgeons a more user-friendly and effective solution.

PolymerExpert has developed several families of hydrophilic coatings (PVP, PU, Polyethers,…) particularly intended for the medical sector. These coatings have the advantage of drastically modifying the surface tension of substrates and allowing better wettability or making surfaces slippery.

ExpertSun is a photochromic polymer developed by PolymerExpert that exhibits reversible color change in the presence of ultraviolet (UV) light. Utilizing advanced polymerizable naphthopyran derivatives, these polymers strike a balance between color intensity and the speed of coloring and fading, maintaining structural integrity even within the polymer matrix. This resistance to fatigue allows the polymers to be incorporated into a range of applications, from hydrophilic to hydrophobic polymers. In the field of ophthalmics, ExpertSun polymers are utilized in sunglasses and contact lenses, providing protection against UV-induced retinal damage. Notably, PolymerExpert integrates these polymers into intraocular lenses for cataract patients, optimizing visual comfort by adjusting to UV light intensity. The versatility of ExpertSun extends to quality control and safety systems, offering a customizable solution for projects seeking innovative polymer technology.
