Selection of Polymeric Materials steers engineers and designers onto the right path to selecting the appropriate values for each plastic property.

A large amount of property information has been provided to teach and assist the plastic part designer and others in selecting the right resin and properties for an application and includes various standards to help the readers in making sound decisions.

Selection of Polymeric Materials:

• A simple and efficient approach to a highly complex and time consuming task
• Allows engineers to select from various standards including ASTM, ISO, UL, and British Specification
• Presents information on properties such as tensile strength, melt temperature, continuous service temperature, moisture exposure, specific gravity and flammability ratings
• Tried and true values narrow myriad choices down quickly for readers
