ExpertBone - Single-Phase Acrylic Bone Cement

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.

ExpertSurf - Hydrophilic Coatings Polymers

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.

ExpertShape - Memory Shape Polymer

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 - Self-Repairing Polymer Technology

The consumer market is heavily reliant on polymeric materials, which are prone to damage such as impacts, scratches, and cracks that can degrade their appearance and functionality. Recent research initiatives have been driven by both manufacturers and consumers to develop solutions that extend product longevity and performance. One promising solution is the use of self-repairing polymers, which offer the ability to autonomously mend unsightly fractures or damages in specific parts. Two key technologies underpin this innovation: assisted healing and self-healing polymers. In the assisted healing process, encapsulated healing agents are released upon crack propagation, though they have a finite reparative capacity. Conversely, self-healing polymers possess an inherent ability to repair infinitely, facilitated by movements of polymer chains or the reversible formation of bonds. In thermoplastics, this healing is achieved through chain creep or molecular interdiffusion at temperatures above the glass transition, allowing the material to retain mechanical properties over time.
