Materials Performance

Under this category are considerations such as the mechanical properties of the material, its stiffness or flexibility, and its heat resistance, chemical resistance, and dielectric properties.

For example, heat resistance becomes a consideration if a device is meant for autoclave sterilization. For these applications, a heat-resistant high-performance engineering plastic like Ultem™ PEI (polyetherimide) or PEEK™ (polyetheretherketone) might be considered. If high dielectric strength in a thin material is desired, a polyimide tube or sheet may be a good choice. If ease of molding and low cost are important, acryloni-trile-butadine-styrene (ABS) plastic may be a good choice. Determining the properties, performance, and processing of a plastic material for your application are important selection criteria.
