Processing advice Durethan (Injection molding) | | | | The following information applies when the product is processed by injection molding. If other processing methods, such as extrusion, are used, then the parameters can differ considerably from the figures given here. |
Drying Care must be taken to ensure that the pellets are processed in a sufficiently dry state.
| Permitted residual moisture content | 0.12% | | | Drying temperature | 176 °F (80 °C) | | | Drying time | Dry air dryer
2 to 20 hours (depending on starting moisture content) | Fresh air dryer
not suitable |
General injection molding conditions The figures given are the upper and lower limits for the whole range of grades. The melt temperature for the easy-flow grades will generally be selected from the lower end of the range and the melt temperature for standard grades from the upper end of the range.
Actual processing conditions will depend on machine size, mold design, material residence time, shot size, etc.
