SuperPflex® 100

SuperPflex® 100 by Specialty Minerals is a high gloss precipitated calcium carbonate. Acts as an engineered sub-micron functional filler. It is surface treated, fine particle size with unique crystal morphologies and very narrow particle size distribution. Imparts improved performance properties to rigid PVC applications. The ultrafine particle size and narrow particle size distribution permit exceptionally high filler loadings without compromising impact development or ductility.<br> <ul style="padding-left: 40px;"><li>Possesses increased resin extention, impact strength as well as consistent quality. Offers reduced volume formulation cost.</li> <li>Provides improved product quality and reduced scrap.</li> <li>SuperPflex® 100 is used in extruded weatherable profiles and substrates, injection molded housings, fittings, small diameter coduit as well as pipe.</li></ul>

Calofort® S

Calofort® S by Specialty Minerals is a precipitated calcium carbonate.<br> In rigid PVC, it is used to increase impact strength, particularly at low temperatures and give improved surface gloss and whiteness.</li> <li>In plasticised PVC, it gives excellent scuff resistance and improved surface properties.</li> <li>It is a white stearate-coated microcrystalline powder characterized by high surface area, controlled particle shape and high whiteness.</li> <li>It has a tendency to form soft agglomerates due to its small size.</li> <li>It is used in rubber due to its very good reinforcement properties and is particularly useful where hot tear strength is required.</li> <li>Calofort® S is also used in reinforcing filler in polyester molding compound and carrier for additives used in the plastic compound.</li></ul>
