Chemical, Physical and Mechanical Properties of Common Polymers, 1993 International European Extrusion Coating Symposium Proceedings
Thomas Bezigian
Polymers are used in almost every imaginable application today, such as simple bags and pouches, medical and food packaging, aerospace applications and everyday items such as photographic paper. Polymers are processed readily by many methods, extrusion being the most common. Within the class of extrusion processing, blown film, cast film, and extrusion coating are of particular interest to manufacture. The development of the extrusion coating process in 1946 began a revolution that has allowed complex structures to be manufactured to meet ever increasing societal needs. Within a particular class of polymers, all physical and processing properties are derived from four fundamental polymer properties: molecular weight, molecular weight distribution, density, and chain branching. The effect of these parameters on the chemical, physical, and mechanical properties of polymers will be reviewed.
