| **Recycling-specific influences such as slight color deviations, gloss differences, viscosity variations or a higher hardness spreading are possible with TPEs containing a recycled component. |
| All values published in this data sheet are rounded average values. |
| The shelf life of the TPE granules is 24 months from delivery if storage instructions are observed and the product is stored in the unopened original KRAIBURG TPE packaging. Store in dry conditions at room temperature (below 40 °C) away from heat sources and direct sunlight! Contact with nitrogen oxides must be avoided during storage! |

| Processing Guideline Injection Molding | |
|---|---|
| Cylinder Temperature | 180 - 200 - 220 °C, max. 250 °C (360 - 390 - 430 °F, max. 480 °F) |
| Hotrunner | Hot runner temperatures: 200 -250 °C (390 - 480 °F). The runner should be empty after a maximum of 2 - 3 shots. |
| Injection Pressure | 200 - 1000 bar (2900 - 14504 psi) (depending on the size and weight of the part). |
| Injection Rate | In general, the fill time should not be more than 1–2 seconds. |
| Hold Pressure | We recommend to derive the optimum hold pressure from determining the solidification point, starting with 40 % - 60 % of the required injection pressure. |
| Back Pressure | 20 - 100 bar; if color batches are used, higher back pressure is necessary. |
| Screw Retraction | If an open nozzle is used processing with screw retraction is advisable. |
| Mold Temperature | 25 - 40 °C (77 - 104 °F) |
| Predrying | Pre drying of the material is not necessary; if surface moisture forms as a result of changes in temperature, the material should be dried for 2 - 4 hours at 60 - 80 °C (140 - 175 °F). |
| Needle Valve | With materials < 50 Shore A the use of a needle valve is advisable. |
| Screw Geometry | Standard 3-zone polyolefine screw. |
| Residence Time | The residence time is to be set as short as possible with a maximum of 10 minutes. |
| Cleaning Recommendation | For cleaning and purging of the machine it is appropriate to use polypropylene or polyethylene. Machine must be PVC-free. |
