Many polymer systems inherently will yellow and/or darken with extended exposure to temperature. In this lesson we are going to do Polymer Processing part 1 where we will be introducing ways to make libraries a polymers that explore processing conditions. Druckansicht der Internetadresse: document.write(document.URL); Prof. Dr.-Ing. If a material is more resistant to flow and you must make it flow anyway, you have to provide more force and adjust other conditions, like temperature. Barrel and melt temperatures The first consideration in setting barrel temperatures is how much shot capacity will be used.
