Tinius Olsen now launches their latest evolution of melt indexers to meet almost every need. This new model, the MP1500 meets, and surpasses, all the requirements of ISO 1133 and Procedure A, B, C and D of ASTM D1238.
The latest addition to the Tinius Olsen polymer testing line is the MP1500 melt flow indexer, for determination of the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastics according to ISO 1133 and ASTM D1238.
The tester features the latest in melt flow measurement technology where load is applied by a loadcell via a drive system with a PID control feedback, there are no dead weights.
This robust design incorporates quality materials and components and ensures that our reputation for superior system performance, ease of use, and longevity is maintained.
The MP1500 becomes a complete powerful test system with the addition of Tinius Olsen’s Horizon data analysis software.
This unit features a color touch-screen LCD display. Operators can configure the options available for the machine and program user settings (language, units, alarms, etc). Individual test protocols can be set and stored for rapid recall when needed and can be used to control the machine by itself or in conjunction with Tinius Olsen’s Horizon software.
Considerations when using traditional MFIs
The manual nature of traditional melt flow indexers puts operator ergonomics at the forefront of workplace safety. Even with an automated deadweight loader, a person still needs to physically manipulate several steps of the load set up, such as making manual judgements and verifications. This can equate to operator strain and fatigue as well as increased risk of injury.
Repetitive, manual tasks are also a part of the traditional MFI testing process. One example is cleaning the system, which takes time and effort and must be done proficiently to ensure batch consistency and avoid cross contamination among different samples.
The industry is looking towards loadcell-based melt flow testing, not only for operator safety and production efficiency, but also to incorporate better data analysis and reporting, as the world of materials testing continues to become digitized.
Digital melt flow testing simplifies the test environment, like eliminating deadweights and automating between-test cleanings.
