Figure 1: Representative schematic of melt-extrusion processing as a function of pressure. (FIGURE 1 IS COURTESY OF THE AUTHOR) Polymer combinations have been shown in numerous studies to yield ...

Die swell has been used in the plastics industry as a qualitative measure of polymer melt elasticity for quality control. It can also be used in an extrusion process for analysis of extrudate ...

Nowadays, melt flow index (MFI), also known as melt index (MI) or melt flow rate (MFR), is extensively used to quantify polymer flow behavior. MFI is a measurement of the ease at which a molten ...

Guill Tool & Engineering Co. Inc., a global provider of extrusion tooling, has expanded its lab capabilities to better serve ...

Need to fine-tune melt flow in your polypropylene compounds? Struktol’s VMO Series makes it easy. In a recent test, adding just 0.2 percent VMO 208 increased the melt flow index (MFI) from 9 to ...

Formulating drugs for hot-melt extrusion (HME) was one of the topics at the Pharmaceutical Extrusion Seminar organized by Leistritz near the company’s US headquarters in New Jersey in June. Several of ...

The Italian company FIMIC has introduced the self-cleaning double-screen melt filter, ERA, which is designed to provide fine filtration for highly contaminated recycled plastic particularly in blown ...
