We proudly offer reverse engineering laboratory and analysis services for polymeric materials. Our team consists of experienced specialists in the field of identification and analysis of polymer materials, who provide you with the best services by using advanced equipment and modern methods.
Our services include:
1. Analyzing physical and chemical details of polymeric materials: This includes analyzing the mechanical, thermal, electrical, and chemical properties of polymeric materials so that you can know the exact properties of your materials.
2. Microscopic analysis: Using advanced microscopes, we examine the internal and surface structure of polymer materials to identify defects and weak points and provide suitable solutions for improvement.
3. Reverse engineering: If needed, using comprehensive analysis, we will implement the reverse process and help to optimize the formulation and improve the quality of your products.
One of the tests that is used to identify the ingredients of products is the MFR or MFI test. Melt mass flow rate (MFR) or melt mass flow index (MFI) is a property of polymer melt flow that is known as the rheological properties of the material in the melt state. The mass MFR value is the amount of material that passes through a die with specific dimensions and comes out during 10 minutes under a certain pressure and at a certain temperature.
A polymer consists of chains of different lengths, therefore the length of the polymer chain determines the melt flow characteristics. Since it is difficult to accurately control the chain length in the polymerization process, it is the chain length distribution or actually the molecular weight distribution of the polymer that affects the melt flow properties.
The higher the MFR value, that is, during the fixed time (10 minutes), more amount of plastic flows at the test temperature, that is, the resistance to flow of the polymer or plastic is lower and it flows more easily, the flow resistance is We know a concept called viscosity. As a result, the higher the MFR of a polymer, the lower its viscosity.
The importance of the MFR test and the reasons for its use
In the production process of a product, if the MFR value varies uncontrollably and unconsciously in a new batch, it can have destructive effects on the productivity and quality of the product. Therefore, it is very important that the materials entering the production unit are tested with the relevant standards and their accuracy is confirmed.
For example, if the MFR of the material is higher than expected, it can lead to the flash of the injection mold, and as a result, the number of returned products will increase, and it will take days to clean the mold and the injection machine. In the worst case, it may cause serious damage to the nozzle, which will be expensive to replace.
On the other hand, if the MFR value is lower than expected, because the viscosity will be higher and the flowability is lower, it may not fill the mold completely and the number of unhealthy products will increase again.
Our team is looking forward to cooperating with you and is ready to provide professional and customized services in the field of polymer materials. For more information and to arrange a free consultation, please contact us.
