Measure the melt flow rate of polymers with Melt Flow Index Junior

The melt flow index (MFI) is an essential property of polymers that measures their viscosity and flow rate. MFI testing is important in the polymer industry because it provides information on how easily a polymer can be processed into a final product. Testing the melt flow index of polymers is an essential property of the material to ensure that the polymer's viscosity and flow properties are consistent, which is important for maintaining product quality. Thus, we at Presto have recently launched a high-quality lab testing instrument known as melt flow index juniorThis is one of the high-quality testing instruments for PET & Bottle testing manufacturers that will help to measure the weight of the sample with great accuracy.

In this blog, we will discuss brief information about the Presto MFI tester and how this quality lab testing instrument is used to test the melt flow properties of polymers. So, let us get started!

Get Accurate Melt Flow Data for polymers with Presto's Melt Flow Index Junior

The melt flow index tester- junior is one of the high-quality lab testing instruments used to measure the melt flow rate of polymers. It is used to measure the weight of the sample with great accuracy. The automatic cutting of samples is one of the highly useful features as it will save time and effort in cutting the samples for testing.

MFI testing is often required by regulatory bodies to ensure that polymers meet specific standards for their intended applications. MFI testing helps manufacturers to optimize their processing conditions by providing information on the polymer's flow properties. This can help to reduce production costs, increase production efficiency, and improve product quality.

Presto's newly launched melt flow index tester is one of the high-quality lab testing instruments that has been designed as per industrial standards that include ASTM D 1238-1992, IS 2267-1972, IS 2530-1963, and IS 10810-1984. This will provide highly accurate lab testing results for polymer testing.

It is designed to determine the melt flow rate (MFR) and melt volume rate (MVR) of polymers under specific testing conditions. This quality lab testing instrument has been designed with user-friendly controls that make it easy for the manufacturers to conduct melt flow tests of the polymers. Now, let us discuss the highly advanced features of this quality lab testing instrument.
