PMI offers advanced materials to meet the growing trends. Our advanced materials are used by medical device and pharmaceutical companies developing products for the many growing trends of less invasive, more cost-effective means for targeted treatments with quicker recoveries and better quality of life for patients.
PEEK (polyetheretherketone) grades are recognized as having a superior balance of chemical and hydrolysis resistance similar to PPS but can operate at higher temperatures.
PEEK (polyetheretherketone) can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers.
PEEK (polyetheretherketone) carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.
Technically PEEK (polyetheretherketone) is part of a family of polyarylether ketones (PAEK) but the PEEK (polyetheretherketone) acronym is most recognized. Related chemistries based on PEK and PEKK offer unique thermal benefits to the traditional PAEK’s.
All PAEK materials are known for their exceptional chemical inertness including to saturated steam. Only a few halogenated acids like HF will attack PAEK materials. All PAEK polymers have a softening temperature of 350-380°F and a melting temperature of 700°F.
PAEK materials readily accept reinforcements and wear resistance additives such as graphite and PTFE leading to some extraordinary wear and heat resistant bearing materials for chemically tough service conditions.
PAEK materials also have V-O flammability ratings and exhibit very low smoke and toxic gas emission when exposed to flame.
Our latest grade, PEEK LSG (Medical Grade, Optima PEEK), & PEEK HPV, offers outstanding properties that can also be viewed below.
