PEEK is a high temperature resistant thermoplastic with a high glass transition temperature (143°C) and melting point (334°C) and a load thermal transformation temperature of up to 316°C (30% glass fiber or carbon fiber reinforced grades)
PEEK main characteristics advantages.
1: High temperature resistance U.S. UL certification long-term use temperature of 260 ℃. Even when the temperature reaches 300°C, it can still maintain excellent mechanical properties
2: Wear resistance in many high temperature, high load, strong corrosion and other extremely harsh application environment, PEEK polymer and its composite materials have good wear resistance.
3: self-lubricating with a low coefficient of friction, oil-free lubrication can be achieved in oil, water, steam, weak acids and bases and other media long-term work.
4: corrosion resistance insoluble in common solvents, to a variety of organic and inorganic chemical reagents, have good anti-corrosion properties.
5: High strength has good mechanical strength in plastics. Also has a high rigidity and surface hardness.
6: Easy processing can be directly processed out of the parts using injection molding process. Post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding can be carried out.
7: Hydrolysis resistance in the temperature of more than 250 ℃ steam or in the high pressure of water immersion, PEEK products can still work continuously for thousands of hours without significant performance degradation.
8: flame retardant without the use of any additives, 1.45 mm thickness of PEEK sample flammability rating of UL94V-0 level.
9: Low smoke and non-toxic combustion when the amount of smoke and toxic gas is particularly low.
10:Electrical performance in a wide range of temperature and frequency, can still maintain a stable, excellent electrical performance.
11: Radiation resistance has a very strong resistance to high dose of γ-ray radiation, mechanical properties can be retained intact, can be used as radiation resistant parts in nuclear equipment.
12: Dimensional stability
