PEEK Engineering Plastic
High-Performance PEEK Sheets, Rods, Tubes, Profiles & Custom Machined Parts
PEEK (Polyether Ether Ketone) is a semi-crystalline high-performance engineering thermoplastic. The supplied Guangdong Zhenghao brochure describes PEEK as a specialty engineering plastic based on a semi-crystalline structure, combining high mechanical performance, high-temperature resistance and excellent chemical corrosion resistance.
Yozonetech supplies PEEK sheet, rod, tube, profiles, semi-finished materials and customized machined components. Available material options include PEEK-Resin, PEEK-GF30, PEEK-CF30 and functional grades such as PEEK-ESD, subject to application and specification.
The following product page is based on the supplied Guangdong Zhenghao PEEK product brochure, including its material descriptions, application fields, processing information and plate/rod specification tables. Where the brochure leaves specification fields blank, no values have been inferred.
PEEK Material Overview
PEEK is positioned in the supplied brochure as a high-performance crystalline engineering thermoplastic for demanding thermal, mechanical, chemical and wear environments. Its molecular structure contains a large number of benzene-ring structures, contributing to its comprehensive performance.
The brochure places PEEK among specialty engineering plastics used around the 300°C class, while the stated glass transition temperature is 143°C and the material is described as maintaining good mechanical properties at temperatures as low as −196°C. Actual continuous service temperature depends on grade, load, environment, geometry and processing conditions.
PEEK combines high-temperature stability, excellent chemical stability, hydrolysis resistance, wear resistance, fatigue resistance, creep resistance, dimensional stability and electrical insulation. These characteristics support its use in aerospace, automotive and energy systems, semiconductor and electronics equipment, food and medical equipment, petrochemical processing, textile machinery and general mechanical manufacturing.
