At least one extrusion barrel must be selected, in accordance with the materials to be tested. Various plastics (e.g. PTFE and PFA) which contain fluorine release hydrofluoric acid, which attacks the extrusion barrel material. For these plastics extrusion barrels made of a special steel alloy are used. These extrusion barrels have only limited suitability for filled plastics. For these the wear-resistant version is recommended.
Test material | Diameter, inner [mm] | Properties | Item No. |
Plastic, not containing fluorine | 9.55 | Wear-resistant | 001331 |
Plastic, containing fluorine / not containing fluorine | 9.55 | Acid-resistant | 001345 |
The die plug prevents premature outflow of the material when plastics with high flow-rates (> 10 cm3/10 min at load 0.325 kg) are being tested. When the die plug is in use, an extrudate cutter is required in order to eject the die plug automatically when the test begins.
