In a world full of industries, quality remains the main factor that makes an industry stand out. Phillips Medisize has a zero defect goal that aims at continuous improvements. In addition, as for a company that manufactures medical devices made out of plastic polymers, degraded components should not be considered as a normal characteristic in a polymer nor as a usable product for the safety of the patients.
This thesis will clarify the method that Phillips Medisize is currently utilizing to measure the molecular weight in a polymer. This method is used in order to acquire the polymer’s properties that determine the degradation levels. The degradation can be visible from the polymer’s behavior. This thesis will also discuss the outer elements that affect the polymers causing it to degrade.
For more accurate and reliable measurements, viscometer devices can be utilized for the sake of grasping as much beneficial information as well as actions to implement during the degradation. Viscometer devices mainly include displays that show the results in a graph form for easier interpretation and less time consumed.
The IhV method influences the determination of the degradation level. It also measures the flow time of a fluid, with and without applying stress to understand the polymer’s behavior. This method has been researched according to the ASTM D4603 standard.
