Melt flow indexers provide plastics processors and recyclers with valuable information that either confirms a polymer's specification on a polymer data sheet or, in the case of recycled material, informs operators of the current melt flow index (MFI) or intrinsic viscosity (IV) of the recycled ...
- ASTM D1238: MFI is reported in terms of Melt Flow Rate (MFR) or Melt Flow Index (MFI) in grams per ten minutes (g/10 min). The term "Melt Flow Index" is more commonly used in ASTM standards. It is important to note that while ISO 1133 and ASTM D1238 have some differences, ...

Typical polymer melts exhibit high viscous behavior, suggesting that the molecular interaction between the polymer chains is strong and hence they resist slipping over each other & cause a drag on the melt flow. These interchain forces can be caused by factors such as chain entanglements, molecular...

Overhead welding or welding in rain and wind? Electrode welding is the simple and versatile solution.
Managing modern software environment hinges on the three “pillars of observability”: logs, metrics and traces. (Sometimes events is included in this:MELT.) Each of these is a data source that provides crucial visibility into applications and the infrastructure hosting them. This practice informs ...

The reflow zone is the most critical stage, where the PCB reaches its peak temperature. The primary objective is to melt the solder paste to form a metallurgical bond between the components and the PCB. Ensuring proper wetting of the solder to create strong, reliable joints. ...
