AMS is the parent company of the Trans-Chemco “TCI Foam Control” brand, Performance Process Inc. (PPI), and Nottingham Company. In 1991, Performance Process, Inc. (PPI) was founded in Mundelein, Illinois to produce fumed and precipitated treated silicas. Nine years later we installed a new state-of-the-art treated silica production unit at our Nottingham Company facility in Atlanta, Georgia, which more than doubled our capacity and reduced delivery time for our customers in the Southeast. In 2015, AMS purchased PPI, and in 2016 we expanded our silica production and consolidated facilities to our Burlington, WI plant. Applications Our fumed and precipitated silicas are used in a wide range of applications that include adhesives, agriculture, cable gels, coatings, cosmetics, defoamers, fire extinguishers, foods, greases, inks, paints, plastics, polyester resins, silicone rubber, silicone sealants, toners, and more. Benefits The benefits of fumed and precipitated silica are diverse. It is an ingredient that works as an adsorbent, and it provides anti-setting, anti-sagging, anti-setoff, anti-blocking, and reinforcement. It encourages the free flow of powders, improvements in mechanical and optical properties, pigment stabilization and dispersion, and print definition. In addition, improvements are achieved when it is used for processability, hydrophobicity control, thickening, thixotropy, rheology control, and suspension and stability behavior. Excellent Quality The foundation of every product we develop is its formulation, and ours lead the industry in accuracy, consistency and performance. In our cutting edge laboratory we have the equipment needed to ensure that procedures are followed meticulously while testing and regulating our formulations. Our attention to detail throughout the process results in substantial savings for our customers in both time and costs. Collaboration It is essential that we collaborate with our customers at every step in the formulation process, from initial discussion through development, installation, production, and performance evaluations. For us, working closely together is the reason for our success. Hydrophobic Silica—Fumed & Precipitated Adsorbent and Carrier Adsorb gaseous, liquid or solid materials and act as a carrier to allow conversion of liquid and pastes into powder, making them considerably easier to dose and handle. Applications Coatings & paints Pharmaceuticals & cosmetics Polyester resins & gel coats PVC based plastics Defoamers and Antifoams Food—direct and indirect applications Paints and coatings Inks Adhesives Paper Textiles Electrostatic Charge Effect Reduce the tendency of plastic powders to acquire a negative electrostatic charge, eliminating characteristics that are undesirable. Applications Batteries Coatings & paints PVC based plastics Free Flow and Storage Greatly increase the free flow and storage stability of powdered substances that have a tendency to cake. Applications Coatings & paints Defoamers & antifoams Pharmaceuticals & cosmetics Polyester resins & gel coats Printing inks PVC based plastics Fire extinguisher powder Table salt Tomato powder Tablet powder blends Plastic powders Toners High Temperature Insulation Outstanding thermal insulation properties due to the fact that amorphous silicon dioxide has a very low solid state conductivity Applications Cable gels Rubber & rubber compounding Thermal insulation Providing Improvements for Many Products Printer and Copier Toner Improve the flow characteristics and charge stability and enhance the resolution and print quality of toners. Applications Printing inks and toners Reinforcement of Elastomers Improve mechanical properties, such as tensile strength, elongation at break, and tear resistance, and help control the influence of temperature on mechanical properties. Applications Adhesives & sealants Rubber & rubber compounds Molding, sealing, & casting compounds Suspension, Dispersion and Grinding Prevent or delay sedimentation of solids in liquid systems, re-disperse settled sediments without problems, and break down solid particles and prevent them from recombining. Applications Coatings & paints Resins containing fillers Thickening and Thixotropy Particles restore original viscosity when in a state of rest, reversing thickening with a minimum amount of energy. Applications Adhesives & sealants Cable gels Greases Polyester resins & gel coats Resins containing fillers Storage and Stability Remains chemically stable when stored under dry conditions, protected from volatile substances, and used within two years.
