What Is The MFI Test For Plastics?
Posted on 17 July, 2023 by Vishal Malhotra
Plastic products are more versatile and widely used materials in different industries and testing these products accurately will ensure their suitability for specific applications. One of the crucial properties of plastics is the melt flow properties that plays an important role in processing the behaviour and functionality of plastics in molding operations. Thus, we at Presto has designed one of the high-quality lab testing instrument known as the melt flow index tester for plastics. This high-quality laboratory testing equipment will accurately assess the flow properties of molten plastics or resins and ensure that quality materials will be delivered to the customers.
The Presto Melt Flow Index tester accurately provides all standard terms of temperature and pressure strictly as per standards ASTM D 1238-1992, ISO 1133, IS 2267-1972, IS 2530-1963, IS 10810-1984. This will ensure accuracy in test results.
In this blog, we will discuss brief information about melt flow index tests for plastics and how our lab testing equipment is useful in conducting these tests.
Importance of conducting melt flow test on plastics
The melt flow index (MFI) test is an important procedure conducted on plastics to assess their flow characteristics under specific conditions. It measures the rate at which a polymer melts and flows through a standardized orifice at a constant temperature and pressure.
This important property of plastics will help to determine the viscosity of melted plastics and help manufacturers determine the molten properties of the materials to ensure accuracy in finished products.
You can easily read brief information about why you should take melt flow index measurements for plastics.
Our MFI tester for plastics has been designed to assess the flow properties of these materials and ensure that quality materials will be delivered to the customers.
This testing equipment comes with a rigid metal base to ensure stability during operation. It plays a significant role in determining the flow properties of plastics. You can read more on the significance of melt flow index tester in the plastic industry.
Now, let us discuss a brief about melt flow index testing instruments and why it is important to conduct melt flow index tests on the materials.
All about Presto melt flow index tester
As we have discussed above the melt flow index is considered to be an essential property of the plastics that will help to evaluate the rate at which the plastic will flow. This test will be carried out under prescribed conditions of temperature, load and piston position in a cylindrical cavity inside a heated metallic tube barrel.
Thus, to ensure that this test will be performed accurately; manufacturers can easily make use of a reliable and most-trustworthy melt flow index tester. Users can easily perform quality checks of polymers using this highly accurate lab testing equipment.
Now, let us discuss the features and technical specifications of this quality testing equipment.
