Polyetheretherketone refers to a linear polymer whose main chain consists of aromatic groups, ketone bonds and ether bonds. It is the only polyaryletherketone variety that can be mass-produced at present. Its English name is polyetheretherketone, or PEEK for short.
Polyetheretherketone has the heat resistance and chemical stability of thermosetting plastics and the molding processability of thermoplastics. PEEK also has excellent heat resistance. Its heat deformation temperature is 160ºC. When reinforced with 20% to 30% glass fiber, the heat deformation temperature can be increased to 280 to 300ºC. PEEK has good thermal stability, 420°C in air. The weight loss is only 2% at 2h, and 2.5% at 500ºC. Significant thermal weight loss occurs at 500ºC. The long-term use temperature of polyetheretherketone is about 200ºC. At this temperature, it can still maintain high tensile strength and flexural modulus. It is also a very strong material with excellent long-term creep resistance and Fatigue resistance.
Features
Mechanical properties: PEEK is a plastic that has both toughness and rigidity and achieves a balance. In particular, its excellent fatigue resistance to alternating stress is the most outstanding among all plastics and is comparable to alloy materials.
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.
Chemical resistance (corrosion resistance): PEEK has excellent chemical resistance. Among common chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.
Flame retardant: PEEK is a very stable polymer. A sample with a thickness of 1.45mm can reach the highest flame retardant standard without adding any flame retardant.
Peeling resistance: PEEK has good peeling resistance, so it can be made into thinly coated or electromagnetic wires and can be used under harsh conditions.
Fatigue resistance: PEEK has the best fatigue resistance among all resins.
Radiation resistance: It has a strong ability to resist high radiation, exceeding the best radiation resistance of polystyrene among general resins. It can be made into high-performance products that can still maintain good insulation capabilities when the γ irradiation dose reaches 1100Mrad.
Hydrolysis resistance: PEEK and its composite materials are not chemically affected by water and high-pressure water vapor. Products made of this material can still maintain excellent properties when used continuously in high-temperature and high-pressure water.
