PEEK material with high-performance engineering plastic in excellent heat resistance, chemical resistance, mechanical strength and dimensional stability

PEEK

PEEK material with high-performance engineering plastic in excellent heat resistance, chemical resistance, mechanical strength and dimensional stability

It is a semi-crystalline, thermoplastic special engineering plastic developed by the British Imperial Chemical Industry Company (ICI) in 1978. Because PEEK has excellent comprehensive performance such as high temperature resistance, self-lubrication, corrosion resistance, flame retardant, hydrolysis resistance, wear resistance and fatigue resistance, it is used in the field of national defense and military industry, and gradually expanded to the civilian field, including industrial manufacturing, aerospace, automotive industry, electronic and electrical and medical equipment. With the continuous improvement of PEEK synthesis and processing technology, the high performance materials obtained by chemical modification, blending and composite filling have expanded its application field. PEEK is suitable for injection molding, extrusion molding, die molding and melt spinning and other processing methods, with the development of large aircraft, rail buses, automotive industry, medical and national defense industry, the demand for special engineering plastics represented by PEEK is also increasing, especially in improving the production and processing capacity of high-performance products.

    PEEK material is a high-performance engineering plastic with excellent heat resistance, chemical resistance, mechanical strength and dimensional stability.

    Characteristics And Application Areas Of Peek Material

    1. High temperature field: PEEK material performs well in high temperature environments and can withstand temperatures up to 300°C. Therefore, it is widely used in aerospace, automotive, chemical, energy and other fields of high temperature parts manufacturing.

    2. Chemical corrosion field: PEEK material has good chemical corrosion resistance and can maintain stable performance in a variety of chemical media such as acids, alkalis and organic solvents. Therefore, it is widely used in the manufacture of chemical equipment, pipes, valves and other components.

    3. Medical field: PEEK material has the characteristics of biocompatibility and non-toxic side effects, so it is widely used in the manufacture of medical devices and artificial organs. For example, vascular stents, artificial joints, tracheal intubation and other products made of PEEK materials have been widely used in clinical practice.

    4. Electronic field: PEEK material has excellent electrical insulation properties and mechanical strength, so it is widely used in the manufacture of electronic equipment. For example, cable bushings, connectors, sockets and other products made of PEEK materials have been widely used in power, communications, computers fields.

    5. Automotive industry: PEEK material has good heat resistance and mechanical strength, also has good friction resistance and chemical corrosion resistance. Therefore, it is widely used in the manufacture of automobile engine parts, transmission system parts, brake system parts. 

    PEEK materials have a wide range of applications and can meet the high performance requirements of different industries and fields. Through reasonable material selection and processing technology, high quality and high performance PEEK products can be produced
