The expected shelf life of the TPE granules is a minimum of 24 months from the date of delivery, provided that the storage instructions are followed and the product is kept in the unopened original KRAIBURG TPE packaging. Dry conditions at room temperature (below 40 °C/ 104 °F), away from heat sources and direct sunlight, must be maintained for proper storage. Contact with nitrogen oxides during storage should be avoided. |

Processing Guideline Injection Molding | |
---|---|
Cylinder Temperature | 180 - 210 - 240 °C, max. 250 °C (360 - 410 - 460 °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 | The mold temperature depends on the hard component. A temperature exceeding 80 °C (175 °F) should be avoided. The common temperature is 40 - 60 °C (105 - 140° F). |
Predrying | To achieve optimum mechanical values, drying the material for 2 - 4 hours at 60 - 80 °C (140 - 175 °F) is recommended. |
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. |
Dry conditions at room temperature (below 40 °C/ 104 °F), away from heat sources and direct sunlight, must be maintained for proper storage. Contact with nitrogen oxides during storage should be avoided.
