An extremely high temperature resistance combined with excellent mechanical, electrical, and chemical resistance makes PEEK™ (Polyetheretherketone) a high performance semi-crystalline thermoplastic suitable for use in a wide variety of demanding applications.
While maintaining similar dielectric properties, this film features higher tear and chemical resistance than Kapton® Polyimide HN, FN, and CR films, as well as better barrier performance against oxygen and water vapor, lower moisture absorption, and superior resistance to hydrolysis. This makes PEEK™ film well suited to hot, humid environments.
Mechanically, this film is capable of a high tensile strength of 18.9 kpsi (130 MPa), a flexural strength of 23.6kpsi (163 MPa) and a Rockwell hardness of 99 (R Scale).
PEEK™ is capable of maintaining its properties up to very high temperatures (continuous use of -70 to 500F), is UL RTI rated up to 464F, and has a melting point of 644F. PEEK™ also boasts a heat deflection temperature (1.8MPa) of 306F. 0.012-0.280mm thickness carries an HB flammability rating, while 0.50-0.75mm has a V-1 rating.
PEEK™ meets many aerospace, automotive, fire, smoke and toxicity, food/water, medical/pharmaceutical, and military approvals and standards. Custom sized sheeting available. PEEK™ is available with adhesive as well, exclusively from CS Hyde Company as PEEK Tape.
