The raw material of polycarbonate … It could be noted form Fig. In other words, the plastic likes to go fast; it has lower viscosity… High-viscosity Epoxy Resins / Laminating Resins Many thicker and therefore highly viscous or medium viscous epoxy resins are reminiscent of honey … Thus, the viscosity … This means their apparent viscosity (η) 1 depends on the applied shear rate and increases rapidly with increasing molecular weight (number of repeat units). A Helpful Guide to Processing High Viscosity Resins The term “viscosity” refers to the thickness or flow-ability of a liquid. An example of a high viscosity liquid is syrup. What is viscosity in a plastic? 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 … For example, a substance with a thick viscosity resists movement while a low viscosity … Viscosity is not changing much in this section; it is a flat line, something like the way water flows. 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. … I did a search for "table of viscosity values" and this was the second link: Viscosity Values Chart *Centipoise = centistokes x specific gravity where … Flow Properties of Polymers Time-independent Fluids. ... Basf's famous high … Low viscosity refers to substances that are thin, such as water, while high viscosity substances are thick. Polycarbonate or "PC" is a highly useful engineering thermoplastic. In addition to measuring thickness, viscosity measures resistance to motion. Polymer solutions, dispersions, and melts are usually non-Newtonian liquids. For process stability, the plastic likes the flat section of the curve, as shown in the center to right side of graph. It has desirable physical properties such as transparency, high toughness, and very good heat resistance. Polycarbonate – High Viscosity This specification covers the properties of a transparent or pigmented, injection molding grade, pellet form, polycarbonate. 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. Polycarbonate Phenyl salicylate 2,2-dihydroxybenzophenone Thermal degradation. Waste polycarbonate will degrade at high temperatures to form solid, liquid and … 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.
