Materials Properties and Determination of Characteristic Values for MID

Users can select from a wide offering of plastics with different properties profiles (Fig. 2.3). Over the course of time, the compelling search for more and more high-capability materials has extended the range of standard plastics and engineering plastics to include many high-specification polymers. 

Obviously, therefore, the expectations that apply to any base material impinge on decision-making processes at several different levels. Alongside purely technical aspects such as intrinsic loadability and compatibility and the basic workability properties, ecological factors (e.g., suitability for return to the natural materials cycle) and of course economic factors (e.g., procurement costs and processing costs) influence materials development and selection. 

The properties that characterize plastics are presented below, along with the test methods and processes for gauging these properties. The information is offered here with the objective of developing and expanding awareness for this group of materials. 

Broadly speaking, plastics characteristic values are measured 

To this extent, therefore, these characteristic values are also definitive for MID, the properties of which are ultimately based on the thermoplastic or thermoset behavior of different base materials.
