� Tend to be transparent � Higher creep resistance � Higher dimensional stability � Tend to be translucent or opaque � Lower fatigue resistance � Lower dimensional stability � Bond well using adhesives and solvents � Higher fatigue resistance � Lower chemical resistance and resistance � Difficult to bond using adhesives and to stress cracking solvents � Structural applications only (not for � Higher chemical resistance and resistance bearing and wear) to stress cracking � Good for bearing and wear, as well as for structural applications The general properties of amorphous and crystalline polymers Simply knowing if a polymer is amorphous or crystalline will help define its behavior and many of its properties. The Periodic Table of Thermoplastics (developed by Tangram Technology Ltd.) depicts how the distinction between amorphous and crystalline polymers represents one of the fundamental divisions in the thermoplastics family. It is shown on the following page. Page 6 of 9 Copyright ©2007-2010 Zeus Industrial Products, Inc.
