PEEK Machined Parts
Polyether ether ketone (PEEK) is a popular high strength plastic resin, ideal for parts that require strength and stiffness. It has an extremely high resistance to heat, moisture, and chemicals and can withstand multiple cycles in hot water or steam. PEEK also performs well in ultra-high vacuum environments.
PEEK has a machining cost factor of 0.9 when compared to steel 12L14.
