PEEK has excellent comprehensive performance due to its molecules containing a large number of benzene ring structures. It has excellent high temperature resistance (over 260°C) and corrosion resistance, and has good mechanical properties, impact resistance, self-lubrication, flame retardancy and other characteristics. Today, let’s talk about the advantages of PEEK in terms of high temperature resistance and corrosion resistance!
PEEK is super high temperature resistant
Chart of melting point and long-term use temperature of several special engineering plastics
From the figure, we can see that the melting point and long-term use temperature of PEEK are higher than those of the other four thermoplastic special engineering plastics. Therefore, PEEK material can show good heat resistance.
The specific performance of PEEK’s high temperature resistance can be tested by high temperature bending and high temperature compression. As shown below:
PEEK5600G and PEEK5600CF30 high temperature bending performance and high temperature compression curves
As can be seen from the above figure, like all plastics, as the temperature rises, its mechanical properties are gradually reduced. However, due to its excellent temperature resistance, PEEK can still maintain about 70% of its original performance at 100°C.
PEEK super corrosion-resistant

As can be seen from the figure, the corrosion resistance of PPS and PEEK is basically the same, while the corrosion resistance of PPSU, PEI, and PI is worse than that of PEEK.
PEEK products have excellent chemical resistance. Among common chemicals, only concentrated sulfuric acid can dissolve or destroy it. Its corrosion resistance is similar to that of nickel steel.
