PEEK Introduction and Characteristics

Polyetheretherketone resin (PEEK resin for short) is a new type of semi-crystalline aromatic thermoplastic engineering plastic made by condensation reaction of 4,4′-difluorobenzophenone and hydroquinone in the presence of alkali metal carbonate and diphenyl sulfone as solvent. It is a high-temperature resistant thermoplastic plastic with a high glass transition temperature (143°C) and melting point (334°C), and a load heat deformation temperature of up to 316°C (30% glass fiber or carbon fiber reinforced grade). It can be used for a long time at 250°C. Compared with other high-temperature resistant plastics such as PI, PPS, PTFE, PPO, etc., the upper limit of the use temperature is nearly 50°C higher;

1. High temperature resistance PEEK has a high glass transition temperature and melting point (334°C), which is one of the reasons why it can be reliably used in applications requiring heat resistance. Its load heat deformation temperature is as high as 316°C, and the continuous use temperature is 260°C.

2. Wear resistance PEEK material has excellent wear resistance in harsh environments such as high temperature, high load, and strong corrosion.

3. High strength PEEK has good mechanical strength, toughness and rigidity, and is a balanced plastic. In particular, its excellent fatigue resistance to alternating stress is outstanding among all plastics and comparable to alloy materials.

4. Self-lubricating property PEEK has outstanding sliding properties among all plastics and is suitable for use in applications that strictly require low friction coefficient and wear resistance. In particular, PEEK modified by mixing carbon fiber and graphite in a certain proportion has better self-lubricating properties.

5. Chemical resistance (corrosion resistance) PEEK has 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.

6. Flame retardancy : PEEK is a very stable polymer. A 1.45 mm thick sample can reach a high flame retardant standard without adding any flame retardant.

7. Peel resistance : PEEK has good peel resistance, so it can be made into thinly coated wires or electromagnetic wires and can be used under harsh conditions.

8. Fatigue resistance : PEEK has the best fatigue resistance among all resins.

9. Electrical properties PEEK can maintain stable and excellent electrical properties over a wide range of temperature and frequency.

10. Radiation resistance : It has a strong resistance to gamma radiation, which exceeds the radiation resistance of polystyrene among general resins. It can be made into high-performance wires that can still maintain good insulation performance when the gamma radiation dose reaches 1100 Mrad.

11. Hydrolysis resistance PEEK and its composite materials are not chemically affected by water and high-pressure steam. Products made of this material can still maintain excellent properties after continuous use in high-temperature and high-pressure water.
