Poly-ether-ether-ketone (PEEK<\/a>) is a thermoplastic special engineering plastic with excellent performance in abrasion resistance, temperature resistance, corrosion resistance, etc., which can meet various complex Material requirements of parts and components under working conditions and harsh environments. In recent years, with the introduction of domestic PEEK raw materials, the price of raw materials has been reduced, and they have been widely used in more and more industries.<\/p>\n

Vacuum coated PEEK insulation 2<\/p>\n

Material properties<\/p>\n

1. Mechanical properties
\nThe tensile properties of PEEK materials are better than most thermoplastic materials. As the temperature rises, PEEK can still maintain very stable tensile strength in a large temperature range. At high temperature, the bending strength, creep resistance and compressive strength of PEEK materials have good performance, and the impact resistance at room temperature is better than polyimide PI, PPS, PAI and other materials.<\/p>\n

2. Temperature resistance
\nPEEK has a glass transition temperature of 143 \u00b0 C and a melting point of 343 \u00b0 C. However, because PEEK is a semi-crystalline material, PEEK can still maintain good mechanical properties in the range close to the melting point temperature. The thermal deformation temperature of PEEK is higher than that of PPS, and the continuous use temperature of PEEK is 250 \u2103. After 100,000 hours of continuous use at high temperatures, PEEK performance can still maintain 50% of normal temperature.
\nThe natural color of PEEK is flame retardant, and it can reach UL94-V0 level without adding any flame retardant. During high temperature decomposition, carbon dioxide and carbon monoxide are mainly produced, and the content is very small.<\/p>\n

3. Electrical performance
\nPEEK material has good electrical insulation. At 150 \u2103 to room temperature, PEEK volume resistivity is little affected by temperature. The surface resistivity of PEEK is better than conventional thermoplastic materials such as PTFE, PET, PI, etc. It is widely used in high-voltage electrical fields.<\/p>\n

Four, wear resistance
\nPEEK is a wear-resistant grade modified by graphite, PTFE, molybdenum disulfide, etc. It has excellent wear resistance, even if the unmodified pure resin PEEK still has good self-lubricity. Under the same conditions, the limit wear rate of PEEK is higher than that of conventional friction materials such as POM, oil-bearing bronze, and alloys.<\/p>\n

5. Corrosion resistance
\nPEEK has the corrosion resistance second only to fluoroplastics. Except for some highly oxidizing acids, PEEK can withstand most acids, alkalis, organic solvents, etc. (please contact Ruilu for details).<\/p>\n

6. Radiation resistance and hydrolysis resistance
\nMost plastics become brittle when subjected to electromagnetic or ionic radiation. PEEK can still work normally under high dose of ionizing radiation, and can still maintain good mechanical strength under high temperature steam environment<\/p>\n

Main applications and brands
\nBecause PEEK has good comprehensive performance, it is widely used in aerospace, petrochemical, new energy, automotive, electronic semiconductor, robot automation and other fields.<\/p>\n","protected":false},"excerpt":{"rendered":"
