1. What is PEEK?<\/span><\/h1>\n

 <\/p>\n

PEEK (Polyetheretherketone) is a high-performance specialty engineering plastic belonging to the polyaryletherketone (PAEK) family. Known for its high-temperature resistance, mechanical strength, chemical resistance, and wear resistance, it is considered the plastic with properties closest to those of metal.<\/span><\/p>\n

PEEK is often used to replace metal or high-cost alloys in many extremely demanding applications and is a core material in industries such as aerospace, medical, and automotive.<\/span><\/p>\n
