Modular Melt Flow (MFI)

 | Post date: 2021/01/10 | 



Specification:

Device model: 7025,000
Manufacturer: Ceast
Country of manufacture: Italy


Description of test:

Melt flow index is used as a simple and fast quality control tool. In addition, it is commonly used to detect degradation during the process or to confirm the stability of material properties in different products and to validate products. The possibility of extruding polymers can also be considered.

The weight of a polymer melt extracted in grams per 10 minutes from a die of specified dimensions at a given temperature under a specified weight is called MFI.


Services available:

  • Determine MFI and MVR
  • Quality control and product approval
  • Verification of material fluidity in the desired range


Sample preparation:

The required sample can be in any shape if it can be inserted into the slot of the cylinder. For example, powder, granules, film pieces or molded pieces that can be shredded to make it desirable.


Applicable standards:

  • ASTM D1238     (Method A, B)
  • ISO 1133          (Method A, B)


Limitations:

  • Oven temperature range: from 50 to 400 degrees Celsius
  • Piston load: from 0.5 to 21.6 kg
