Cflow applications
The compact Cflow extrusion plastometers were designed as stand-alone instruments for quick verification of melt mass-flow rates (MFR). They are primarily used for incoming goods inspection at plastics processors where melt flow tests are carried out sporadically and no PC connection is required.
The Cflow is designed for MFR tests to method A. Tests can be performed according to the following standards: Method A to ISO 1133, ASTM D1238, ASTM D3364, JIS K 7210.
| Standards | Test Methods | Typical measurement range | Weight levels | Level of automation | Range of application |

Cflow Advantages & Features
- Temperature control of the heating elements, heating chamber and barrel are all perfectly co-ordinated. The temperature is generated at the location where it is utilized, ensuring excellent temperature distribution over the whole barrel height from the outset.
- Simplified cleaning, with rapid expulsion of residual specimen material.
- The die plug is located on the underside of the extrusion barrel. Removing the die plug frees the die to move downwards, allowing it to be removed easily.
- Expelling the die plus residual material after the test is similarly fast and easy. The barrel is now accessible throughout., simplifying cleaning. - The optionally available test weight support allows you to retain the test weight in the pre-heating position.
- Comprehensive accessory range including automatic or manual extrudate cutter, separating pane and die plug is optionally available.

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.
