Plastics Additives and Testing will have a profound impact both on attaining improved plastics processing and on meeting the desired quality end products. The book is considered as a vehicle to foster recognition and critical examination of the interaction between chemistry of additives and testing. Inorganic or organic chemicals are widely used as additives in plastics processing operations. The existence of process and end products of plastics has radically changed our thinking with respect to performing chemical analyses on additives. Testing is now necessarily an integral part to subject raw materials used in plastics processing. Instrumental methods used in plastics additive testing have the ability to control experiments on plastics processing, to collect data, and to perform calculations with ever increasing efficiency to reduce wastage during processing. Today, it is common practice to use analytical techniques to improve the processing. Now, because of the potentially critical problems in meeting quality products, a reasonable balance must be drawn between control requirements and parameters for improved processing method with respect to plastics additives. This book details this balance and should be seen as a practical reference for plastics engineers, technicians and processors, as well as academics and researcher.
