Overview of melting index tester

Melt index tester is a device used to test the melt fluidity of thermoplastic polymers. Its principle is to evaluate the melt performance of materials by measuring the extrusion amount of melt through the orifice at a certain temperature under certain conditions. The equipment is widely used in plastics industry, chemical industry, material science and other fields, and is one of the important laboratory equipment in thermoplastic polymer quality control and research and development.

Second, the use of melting index tester

The main purpose of the melt index tester is to measure the melt flow of thermoplastic polymers, which is used to evaluate the physical properties and processing capacity of the material. Specifically, its main uses are as follows:

1. Plastic processing control: The melting index tester can be used to determine the melting performance of the material, and then control the product appearance, size and other quality indicators.

2. Material properties research: Melt index tester can be used to test the fluidity of materials, and then determine the properties of materials, including physical and chemical properties, thermal properties, mechanical properties of the study.

3. New material development: Melting index tester plays an important role in the development of new materials, by testing its melting flow performance, you can evaluate the processing performance of the material and the adaptability of special purposes.

Third, the function of melting index tester

Melt index tester plays an important role in the processing and development of thermoplastic polymers, and its main functions are as follows:

1. Quality control: The equipment can measure the melting performance of the material, and ensure the quality and stability of the product by controlling the processing parameters.

2. Adjust the formula: the flow performance of the material is tested by the melt index tester, and the formula and processing conditions can be adjusted to improve the processing performance and product performance.

3. Material research: Melt index tester can be used for thermoplastic polymer physical properties research and development of new materials. By testing the melt flow properties of different materials, performance comparison and material screening can be carried out, which provides an important reference for the development of new materials.
