| 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 Extrusion | |
|---|---|
| Cylinder Temperature | 160 - 180 - 200 °C, max. 250 °C (320 - 360 - 390 °F; max. 480 °F) |
| Screw Geometry | Standard three-zone screw (e.g. polyolefin screw). The screw must be able to provide sufficient shearing. |
| L/D Ratio | At least 25 |
| Compression Ratio | At least 3.5 : 1 |
| Screens / Breaker Plate | A breaker plate and a screen pack are generally recommended in the extruder configuration in order to increase pressure. |
| Die Land | <= 3 mm ( <= 0,12 in.) |
| Extruder Head | Ca. 200 °C (390 °F) |
| Die Temperature | Ca. 200 - 230 °C (390 - 450 °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). To avoid porosity in the profile a pre drying is recommended for wall thickness > 3mm. |
| Calibration | Generally not necessary; support elements may be required when extruding THERMOLAST® compounds with high hardness or when coextruding with standard thermoplastics. |
| Cleaning Recommendation | For cleaning and purging of the machine it is appropriate to use polypropylene or polyethylene. Machine must be PVC-free. |
