Applications: Bearings, cylinder parts and pumps; cable protection; good with ultra-high vacuum applications.
Contemplations: PEEK is an elite material, and, subsequently, is extremely costly.
Advantages: PEI, or Ultem, like PEEK, it’s utilized as a part of medical, aviation and car businesses for its heat protection and fire resistance; fantastic quality and dimensional steadiness; and great chemical protection.
Applications: Medical and chemical instrumentation, flatware, HVAC , electrical and lighting.
Contemplations: Ultem is likewise extremely costly, however not as expensive as PEEK. Take a gander at PPSU as a conceivable option.
