Only a limited number of these substances have been widely studied. We systematically investigate plastic monomers, additives, and …
Processing. Some mineral fillers may be light and fluffy because of low bulk density, requiring special equipment and processing techniques to be added to and dispersed evenly in the polymer. Once encapsulated in the plastic, however, the compound pellets can easily be fed into an extruder or molding machine.
Anti-blocking additives reduce blocking at the surface of polymer films and other plastic articles to allow easier processing and handling. Traditional inorganic anti-blocking additives, such as silica or talc, work by reducing polymer to polymer contact and micro-roughening of the surface, but often affect the clarity of the polymer at higher ...
Additives are absolutely essential in the development of commercial polymeric materials. Accordingly, an exhaustive control of composition and evolution in these additives over time is necessary to validate their performance and safety during their shelf life and, consequently, their ultimate applications. Gas chromatography coupled with mass …

ID = 1.66) means that there is enough space in the process chamber to ensure a good dispersion and high throughput. The additive feed often poses a challenge in processing: if additives with a low melting point are added, they could already melt in the side stuffer. This would lead to a block-age in the side stuffer. The formulation consistency can
Extremely fine (submicron) powders are best conveyed with a flexible screw system because the amount of dust created by the process is minimal and requires little or no air filtration at the discharge point. Abrasive compounds containing reinforcement or conductive additives pose unique challenges. With flexible screw conveying, the inner screw ...
