poly (ether-ether-ketone); PEEK
is a polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure, which is a special polymer material. It has physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a type of crystalline polymer material with a melting point of 334¡ãC, a softening point of 168¡ãC, and a tensile strength of 132-148MPa. It can be used as a high temperature resistant structural material and electrical insulation material, and can be composited with glass fiber or carbon fiber to prepare reinforcement materials. It is generally a type of polyarylether polymer obtained by condensation with aromatic dihydric phenols.

PEEK Sheet English Name Polyetheretherketone
It is a high-temperature resistant thermoplastic with a high glass transition temperature (143¡ãC) and melting point (334¡ãC), and a load thermal deformation temperature of up to 316¡ãC ( 30% glass fiber or carbon fiber reinforced grade), can be used for a long time at 250¡æ, compared with other high temperature resistant plastics such as PI, PPS, PTFE, PPO, etc., the upper limit of the use temperature is nearly 50¡æ higher; PEEK sheet not only has better heat resistance than other high temperature resistant plastics, but also has high strength, high modulus, high fracture toughness and excellent dimensional stability; PEEK sheet can maintain high strength at high temperature, its bending strength at 200¡æ is about 24MPa, and its bending strength and compression strength at 250¡æ are still 12~13MPa; PEEK sheet has greater rigidity, better dimensional stability, and smaller linear expansion coefficient, which is very close to Metal aluminum material; 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. At the same time, it has flame retardancy, releases less smoke and toxic gases under flame conditions, and has strong radiation resistance; PEEK resin has good toughness, and its excellent fatigue resistance to alternating stress is the most outstanding among all plastics, comparable to alloy materials; PEEK resin has outstanding tribological properties, excellent resistance to sliding wear and micro-wear, especially it can maintain high wear resistance and low friction coefficient at 250¡ãC; PEEK resin is easy to extrude and injection mold, with excellent processing performance and high molding efficiency. In addition, PEEK also has excellent properties such as good self-lubrication, easy processing, stable insulation, and hydrolysis resistance, which makes it widely used in aerospace, automobile manufacturing, electronics and electrical, medical and food processing. The material has excellent dielectric properties before the temperature reaches 260 degrees. And it can resist energy ray irradiation.
PEEK sheet has excellent comprehensive properties, good mechanical properties, high temperature resistance, and excellent chemical resistance, making it the most versatile advanced plastic. PEEK (polyetheretherketone) is known as the five major special engineering plastics together with PPS (polyphenylene sulfide), PSF (polysulfone), PI (polyimide), PAR (polyarylate), and LCP (liquid crystal polymer).
PEEK-1000 is made of pure polyetheretherketone resin as raw material. It has the best toughness and impact resistance among all PEEK grades. PEEK-1000 can be sterilized using the most convenient sterilization method (steam, dry heat, ethanol and Y-rays), and the raw material composition of PEEK-1000 complies with the EU and US FDA regulations on food compatibility. These characteristics make it very common in the medical, pharmaceutical and food processing industries.
The addition of PTFE, graphite and carbon fiber makes PEEK-HPV a bearing grade plastic. Its superior friction properties (low friction coefficient, wear resistance, and higher peak pressure limit) make it an ideal material for this level of friction applications.
This material is a reinforced plastic filled with 30% glass fiber. It has better rigidity and creep resistance than PEEK-1000, as well as better dimensional stability, making it ideal for manufacturing structural parts. It can withstand fixed loads for a long time at high temperatures. If PEEK-GF30 is used as a sliding part, its adaptability should be carefully examined because glass fibers scratch the mating surface.
This material is filled with 30% carbon fiber reinforcement, which has better mechanical properties (higher elastic modulus, mechanical strength and creep) and more wear resistance than PEEK-GF30, and the carbon fiber reinforced plastic has 3.5 times the thermal conductivity of unreinforced PEEK plastic - dissipating heat from the bearing surface faster.
High temperature resistance PEEK has a high glass transition temperature (Tg=143¡æ) and melting point (Tm=334¡æ), its load heat deformation temperature is as high as 316¡æ, the long-term use temperature is 260¡æ, and the instantaneous use temperature can reach 300¡æ.
Mechanical properties PEEK has rigidity and flexibility, especially its fatigue resistance under alternating stress is very outstanding, comparable to alloy materials.
Self-lubricating PEEK has excellent sliding properties and is suitable for occasions with strict requirements for low friction coefficient and wear resistance. In particular, the wear resistance of PEEK with sliding grades modified with carbon fiber, graphite, and PTFE is very superior.
Corrosion resistance Except for concentrated sulfuric acid, PEEK is insoluble in any solvent, strong acid, and strong alkali, and is hydrolyzed and has high chemical stability.
Flame retardant polyetheretherketone PEEK is self-extinguishing and can reach UL standard 94V-0 level even without any flame retardant.
Easy processing Because PEEK has good high-temperature fluidity and high thermal decomposition temperature, it can be processed in a variety of ways: injection molding, extrusion molding, compression molding and melt spinning.
PEEK plates are widely used in aerospace, medical, semiconductor, pharmaceutical and food processing industries, such as gas separator components and heat exchanger scrapers on satellites; due to its superior friction properties, it has become an ideal material in friction applications, such as sleeve bearings, sliding bearings, valve seats, seals, pump wear rings, etc. Parts for various production lines, parts for semiconductor liquid crystal manufacturing equipment, parts for inspection equipment, jigs for manufacturing, parts related to atomic energy, electronic components, various precision machine parts, parts related to food processing lines, parts related to chemical machinery equipment, parts related to welding machines, parts related to gold plating machines, parts related to metal surface treatment, insulation parts, etc. Important tips Specifications: 1-100MM*610/1000MM*1000MM Above 150 ¡æ (above the glass transition temperature), the mechanical properties of all PEEK-grade plastics decrease rapidly, while the linear thermal expansion coefficient increases rapidly. If the load is large at a temperature exceeding 150 ¡æ, PAI can be selected to manufacture high-temperature resistant parts.
