Viscosity is the resistance to flow that the plastic faces when it is melted, ie if the plastic is too viscous it has difficulty draining through the nozzle of the injector or die of the extruder, as opposed to a plastic of low viscosity that will drain easily. 2, that the melt viscosity of the blend decreases with increasing shear rate at the various temperatures; this behavior confirms the last finding about the pseudo plastic … This means their apparent viscosity (η) 1 depends on the applied shear rate and increases rapidly with increasing molecular weight (number of repeat units). Polycarbonate or "PC" is a highly useful engineering thermoplastic. What is viscosity in a plastic? Low viscosity refers to substances that are thin, such as water, while high viscosity substances are thick. Waste polycarbonate will degrade at high temperatures to form solid, liquid and … In other words, the plastic likes to go fast; it has lower viscosity… It also has a high … I did a search for "table of viscosity values" and this was the second link: Viscosity Values Chart *Centipoise = centistokes x specific gravity where … In addition to measuring thickness, viscosity measures resistance to motion. Flow Properties of Polymers Time-independent Fluids. The raw material of polycarbonate … Polycarbonate Phenyl salicylate 2,2-dihydroxybenzophenone Thermal degradation. For process stability, the plastic likes the flat section of the curve, as shown in the center to right side of graph. Polymer solutions, dispersions, and melts are usually non-Newtonian liquids. … It could be noted form Fig. A Helpful Guide to Processing High Viscosity Resins The term “viscosity” refers to the thickness or flow-ability of a liquid. Makrolon® polycarbonate is extremely robust, lightweight with glass-like transparency and is impact resistant – even at low temperatures. Figure 2 shows the viscosity curves of PC/LDPE (50/50) blend at various temperature and shear rates. High-viscosity Epoxy Resins / Laminating Resins Many thicker and therefore highly viscous or medium viscous epoxy resins are reminiscent of honey … It has desirable physical properties such as transparency, high toughness, and very good heat resistance. Viscosity numbers range from one to millions of centipoise(cps), When it comes to polyurethanes and epoxies, keep in mind that temperature can have a major impact on a resin’s viscosity. An example of a high viscosity liquid is syrup. Thus, the viscosity … Polycarbonate – High Viscosity This specification covers the properties of a transparent or pigmented, injection molding grade, pellet form, polycarbonate.
