Melt Flow Testing Instrument Apply

Melt flow testing instruments are widely used in the plastic processing industry to measure the fluidity of thermoplastics. These instruments measure the rate of flow of plastic under a specified load and temperature. The results obtained from the melt flow testing instruments are used to determine various properties of plastics such as:

1. Melt flow rate (MFR) - This parameter measures the mass of plastic that flows through a specified aperture under a specific load and temperature during a certain period of time. It is an important parameter to determine the extrusion properties of plastic.

2. Melt volume rate (MVR) - This parameter measures the volume of plastic that flows through a specified aperture under a specific load and temperature during a certain period of time. It is used to determine the amount of plastic that can be processed in a given time.

3. Shear viscosity - This parameter measures the resistance of the plastic to flow. It is used to determine the processability of plastic.

4. Molecular weight - Melt flow testing instruments are also used to determine the molecular weight of plastics. High molecular weight plastics have higher melt viscosity and lower melt flow rate, while low molecular weight plastics have lower melt viscosity and higher melt flow rate.

Melt flow testing instruments are essential for quality control in the plastic industry, ensuring that plastic products meet the required specifications and standards.
