Fiber
Impregnated fibers The impregnation of fibers (textile, glass, carbon) is a challenge for many industrial sectors, from coatings to water treatment, including hydrogen storage and various composite applications. The choice and formulation of resins and other impregnation matrices, like the process, are important industrial issues both...
Compact – Tablet
Compact / Tablet The development of formulas suitable both for the compaction and the subsequent application of the compact, whether it concerns its dissolution, as in pharmaceuticals or hygiene, or other uses (brush filler in cosmetics ,...) is a major industrial challenge for many sectors. The current trend to favor so-called...
microcapsule
Microcapsule / Microsphere Microcapsules and microspheres present various interests for industries, encapsulation often being intended to solubilize, protect, transport assets or molecules of particular interest. Often made up of hydrocolloids (alginate, xanthan, etc.), microcapsules, their formulation, their manufacture and their application raise different questions of physical behavior. The sensitivity of microcapsules and microspheres Different processes...
Complex fluid
Complex fluid Complex fluid is often called liquids containing macromolecules or colloidal or more complex structures (low-concentrate polymer solutions, biological liquids, micellar water, micro-algae solutions, etc.). Unlike conventional liquids, these fluids, due to the presence of macromolecules, organelles or others, generally exhibit singular behaviors influencing...
Resin
Resin Resins are one of the most common industrial substances, used as the main constituent of parts shaped by various thermomechanical processes (extrusion, molding, injection, etc.), as an interface or filler product or as a matrix for composites. . Whether thermoplastic or thermosetting, synthetic or biosourced, recyclable or not, the formulation, industrialization and application of...
Semi-solid and solid foam
Semi-solid & solid foam Semi-solid (or semi-rigid) and solid foams are a commonly sought-after state in many industrial sectors, from the food industry to construction and the automotive industry. Food-grade foams are good examples of semi-solid foams; bread, sponges or synthetic foams (polyurethane, polypropylene,...) good examples of solid foams....
Cire
Waxes & waxy products Although they have been used for a long time for many applications (candles, lip balms, depilatory waxes, care products, lubricants, ski wax,... -see the wikipedia article), waxes and their use in complex formulas always constitute industrial challenges. Indeed, the waxes having the particularity of passing from a solid phase...
Powder
Powders Ingredients for manufacturers of consumer products (cosmetics, agri-food, pharmaceuticals, etc.), finished products for the extractive and primary processing industries, powders constitute one of the main physical states of industrial materials. Although widely used in all sectors, the behavior of powders still poses many operational difficulties, from R&D to application,...
Gel & Gelling agent
Gels & Gelling agents Gelled products are common in many industries (agri-food, cosmetics, pharmaceuticals, but also in specialty industrial sectors such as lubricants and greases). Gelling agents, such as xanthan, alginate, guar, pectin, carob, are sometimes also used as simple thickeners or viscosifiers. Control the sensitivity of gels La...
Pasty
Pasty The term "pasty" evasively qualifies the state of materials and products with more or less "soft" textures and behaviors that are generally difficult to flow. In terms of physical behavior, "pastes" generally have non-Newtonian properties (see our Viscosity, Rheology and Confusion article), semi-solid type mechanical strength and properties...
Liquid foam
Liquid foams Liquid foam is a state of industrial materials in cosmetics or hygiene products, but also sometimes a more or less undesirable state appearing in mixing tanks, dosing machines or other injectors. Today, the basic trend of solid cosmetics is fueling a need to better control the formation of liquid foams....
SKIN
Skin Many dermo-cosmetic or pharmaceutical products are applied on or in the skin, with various aims. Whether for the formulation of products, the design of application devices or the understanding of interactions, physical properties at the macroscopic scale (mechanical, rheological, tribological, etc.) play a role that is sometimes crucial and often underestimated. valued. Master the...
Movie
Flexible films The manufacture and application of films, particularly plastic ones, is an important industrial technical challenge, motivated in particular by the search for options that are more respectful of the environment. The sensitivity of the films to the conditions of implementation In addition to the questions of formulation, the various processes of forming or application of the films (extrusion-blow molding, coating, co-rolling, welding, etc.) raise...
