PEEK tape with silicone or acrylic adhesive backing is an excellent alternative to both PTFE (polytetrafluoroethylene) and PI (polyimide) tape.
PEEK Film is well known for its extremely high performance characteristics: It is super-tough, strong, flexible and resistant to very high temperatures and chemicals. This tape has the best combination of friction and wear properties combined with high heat resistance, chemical resistance, purity and electrical insulation. PEEK tape is hydrolytically stable with very low absorption and permeability.
When compared to PTFE tape, PEEK tape exhibits much higher tensile strength, is a tougher, stronger material with better wear performance in aggressive conditions, and has a lower density. When compared to PI tape, PEEK tape has lower moisture absorption, better performance in strong alkaline environments, and higher tear strength.
PEEK tape is able to meet a variety of aerospace, automotive, food/water, medical/pharmaceutical, and military/nuclear approvals and standards.
