Peek rods are rod - shaped objects made of polyetheretherketone (PEEK) material. PEEK is a high - performance engineering plastic with excellent heat resistance, chemical corrosion resistance and mechanical strength. Therefore, it can maintain good physical and chemical properties in harsh environments such as high temperature, high pressure, strong acid and strong alkali. Peek rods are widely used in various fields such as aerospace, electronics, semiconductors, medical equipment, chemicals and automobiles. For example, in the semiconductor and electronics industries, Peek rods can be used to manufacture high - performance insulating parts, corrosion - resistant pipelines, electrical insulating components, etc. Peek rods are a high - performance material with broad application prospects and can provide innovative solutions for engineers in various fields.
