What is the importance of purchasing only Authentic DuPont™ Vespel® shapes?
The DuPont™ Vespel® parts & shapes business produces and markets high quality polyimide based stock shapes. Different manufacturing processes are used to produce shapes of specific size and composition. Product performance is primarily a function of composition and manufacturing process and can be affected by product size. The influence of product size on performance deals with product diameter and not length.
There are different molding methods used to manufacture shapes. One of the molding processes produces shapes that exhibit directional properties while another process can produces shapes without directional properties. Therefore, it is important to determine the suitability of either with or without directional properties for particular application performance needs.
Since Authentic DuPont™ Vespel® shapes are typically the source of machined components, the relationship between process, size, and performance becomes critical to the success of these parts in application. Therefore, it is important to make certain that the particular shape being used is produced by DuPont in the particular size and composition as was specified during the qualification process.
