    Nano Direct Process for Compounding of Nanocomposites

    SPE

    Numerous varieties of polymer nano-composites have been developed on the laboratory scale and characterized regarding their properties. These include, nanofiller based on exfoliated clay, nanosilver, carbon nanotubes (both single and multiple wall geometry), zinc oxide, silica, and graphene among others. Carbon nanotubes (CNT) are of particular interest as they play a pecial role when it comes to improving or creating electrical conductivity in a polymer matrix.

    Long Fiber Reinforced Thermoplastics - New feeding technologies

    Compounding World

    Long Fiber Reinforced Thermoplastics are a recent development in newer technologies where PP or thermoplastic material is directly compounded with long glass fibers (rovings) and then molded in one operation. Long Fiber Thermo-plastic technologies are the buzz of the auto industry in Europe and the US and are one of the most important trends in the plastics industry today. Glass fibers of ½” (12 mm) up to 2“ (50 mm) length give much higher stiffness, strength and toughness than the 1/8“ (3 mm) fibers that have been used for reinforcement for decades.

    Feed Enhancement Technology for low bulk density material into co-rotating twin-screw compounding extruders

    SPE 2011

    Effectively feeding low bulk density material into a co-rotating twin-screw extruder has always been a challenge. However with the introduction of even finer particle size fillers (sub-micron in some cases) as well as new generations of polymer reactor resins, the issue has become even more problematic. This paper will review a new Feed Enhancement Technology (FET) that provides significant improvement for the introduction of fine particle / low bulk density materials into the extruder.

    Continuous extrusion as a tailor-made process for the production of aquatic feed

    International Aquafeed Directory 2011

    With an extrusion test lab that meets the special requirements for the production of aquatic feed, Coperion, well known by their former name Werner & Pfleiderer, offers manufacturers of aquatic feed and aquatic feed adaptations optimum conditions for the development of recipes and the optimization of production processes. This extrusion test lab is at the Coperion site in Stuttgart. It is equipped with a ZSK MEGAvolume PLUS twin screw extruder and the appropriate plant periphery.

    API dispersal through hot melt extrusion

    Manufacturing Chemist

    It has been estimated that 40–60% of drugs in development have poor bioavailability due to low aqueous solubility. This percentage is likely to increase in the future with the increased use of combinatorial chemistry in drug discovery targeting lipophilic receptors. Poor bioavailability results in increased development times, decreased efficacy, increased inter- and intrapatient variability and side-effects, and higher dosages that reduce patient compliance and increase cost. Thus, the ability to improve drug solubility and hence bioavailability through formulation and process technology is critical to improving a drug product’s efficacy and safety and reducing its cost.
