Impact and molecular weight tests determine the resistance of a material

To determine the effectiveness of a molding procedure then plastics must undergo tests. The specimen tested can be grouped into two: physical and chemical tests. The physical tests include tensile testing, impact weight, and molecular weight among others. On the other hand, the chemical test includes analytical testing of polymers among others. With regards to tensile testing, the analysis determines an extension limit vital in determining the material application. This is verified courtesy of the young modulus of a material.

Impact and molecular weight tests determine the resistance of a material to rupture. In particular, the latter determines the distribution of molecular weight thanks to temperature gel permeation chromatography (GPC). While the specimen’s thickness plays a part in determining the strength, material fabrication should not be overlooked.

The analytical test is a broad term that encompasses several tests including toxins, impurities, additives, and blends among many others. Hence, various chemical techniques apply including mass spectroscopy, thermogravimetry analysis, X-ray diffraction for polymers, and Composites among others. For instance, mass spectroscopy is used to determine the elemental quantitative analysis of a material.
