When standard engineering plastics like PEEK or nylon fail under extreme heat or vacuum, engineers turn to . Known as the "pinnacle of high-performance polymers," Vespel polyimide (PI) operates in environments where other materials literally melt or outgas into oblivion.
For quantities exceeding 500, DuPont can "direct-form" parts using high-pressure sintering. This reduces material waste and labor costs for large-scale production runs. 2. Choosing the Right Grade buy vespel
How you buy Vespel depends largely on your production volume and the complexity of your part geometry: When standard engineering plastics like PEEK or nylon
If you need fewer than 500 parts or are in the prototyping phase, it is typically most cost-effective to buy Vespel in "stock shapes"—rods, sheets, plaques, or tubes—and machine them yourself. These are available through master distributors like Boedeker Plastics and Professional Plastics . This reduces material waste and labor costs for
"Vespel" is a family of materials, each tailored with specific fillers to enhance certain properties. Selecting the wrong grade can be an expensive mistake. DuPont™ Vespel® S Line Design Handbook
