Why is an ASTM D 1238-Based Melt Flow Index Tester Important?

Polymer quality testing has been a basic practice among leading industry players however why you are not matching their quality of production after conducting the same class of testing? That can be because of using a poor design and unauthorized quality testing equipment. This blog lets us have more insights on how an efficient Melt Flow Index Tester can help in getting more accurate and acceptable test results.

Role of quality testing in polymer industries

Polymer or plastic material before getting into any shape or size goes through strict testing modules even when they are in raw form. Plastic granules are thoroughly checked for their chemical qualities like melt flow rate (MFR), melt flow index (MFI) or melt volume rate (MVR). These chemical properties have much importance in structuring their intended use. For instance, the manufacturer has received three different batches of one kind of polymer and needs to decide which can be used for making PET Bottles. In such a case, the company always has a set standard requirement of the MFI index of the polymer. By testing all three batches for their melting nature, one can know which is the perfect match for their production. This way one can ensure the quality of the raw material way before actual use and get rid of future construction issues and gain end-user satisfaction.

How an ASTM D 1238-based melt flow testing machine can make a difference?

If a product will be tested using 5 different brands or company machines, they all will produce different results. Also if done manually there can be chances for human errors. To resolve such issues, there are authorised organisations that have designed globally approved standards to be followed by testing equipment. The standards tell how the machine is structured, and what will be angles, length and width of the machine overall. Following these standards can assure precise results in testing.

For conducting melt flow index tests, the standards to be followed are ASTM D 1238 and ISO 1133. Machines designed as per this standard are known to produce the most accurate test results which are accepted globally.
