PEEK SEALS
What are PEEK Seals, Bearings, & Backup Rings?
Polyether ether ketone (PEEK) is an organic thermoplastic polymer. As one of the most popular thermoplastics on the market, PEEK has a unique chemical structure that makes it incredibly strong and stable even under the harshest environments. Due to its strength and superior properties, it is commonly used in sealing applications across numerous industries.
