Product Description

Precision CNC turning PEEK parts for sleeve bearing

The English name of PEEK sheet is Polyetheretherketone, which is a high temperature resistant thermoplastic with high glass transition temperature (143℃) and melting point (334℃).

PEEK is a high polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure, and 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 ° C, a softening point of 168 ° C, and a tensile strength of 132 to 148 MPa. It can be used as a high temperature resistant structural material and electrical insulating material. Composite with glass fiber or carbon fiber to prepare reinforcement. Generally, a type of polyarylene ether polymer obtained by condensation with aromatic dihydric phenol is used.

Special plastic products have been successfully used in automobile engine gearbox parts, wear-resistant gaskets, motor support heads, solenoid valve spool sleeves, textile printing and dyeing machinery chain sleeves, dust covers, pumps, blades, mouth rings, gears , high temperature and high pressure valve gasket, ball packing, compressor valve plate, piston ring, sealing ring (seal ring), guide ring, support ring (retaining ring), mushroom head, single screw air compressor star wheel, medical equipment bones Positioners, semiconductor CMP wear rings, wafers, wafer clamps (tweezers), IC test pads.....

It is a high temperature resistant thermoplastic with high glass transition temperature (143°C) and melting point (334°C), and the thermal deformation temperature under load is up to 316°C (30% glass fiber or carbon fiber reinforced grade), and 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 operating temperature is nearly 50 °C higher; PEEK sheet not only has excellent 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℃ is about 24MPa, and its bending strength and compressive strength are still 12-13MPa at 250℃; PEEK The rigidity of the plate is large, the dimensional stability is good, the coefficient of linear expansion is small, and it is very close to the metal aluminum material; it has excellent chemical resistance, in the usual chemicals, only concentrated sulfuric acid can dissolve or destroy it, it Its corrosion resistance is similar to that of nickel steel, and 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 excellent fatigue resistance to alternating stress. The most outstanding among plastics, comparable to alloy materials; PEEK resin has outstanding tribological properties, excellent resistance to sliding wear and fretting wear, especially can maintain high wear resistance and low friction coefficient at 250 ℃; PEEK resin is easy to be extruded and injection molded, with excellent processability and high molding efficiency. In addition, PEEK also has excellent properties such as good self-lubrication, easy processing, stable insulation, and hydrolysis resistance, making it widely used in aerospace, automobile manufacturing, electrical and electronic, medical and food processing fields. When the temperature reaches 260 The material has excellent dielectric properties up to and including degrees. And can resist energy ray exposure.

PEEK sheet has excellent comprehensive properties, good mechanical properties, high temperature resistance, and excellent chemical resistance, making it the most versatile advanced plastic. PEEK (polyether ether ketone) and PPS (polyphenylene sulfide), PSF (polysulfone), PI (polyimide), PAR (polyarylate), LCP (liquid crystal polymer) have become five major special projects plastic.

Main features:

High temperature resistant polyetheretherketone PEEK has high glass transition temperature (Tg=143℃) and melting point (Tm=334℃), its load heat deformation temperature is as high as 316℃, the long-term use temperature is 260℃, and the instantaneous use temperature is up to 300°C.

Mechanical properties Polyetheretherketone PEEK has rigidity and flexibility, especially the fatigue resistance under alternating stress is very outstanding, which is comparable to alloy materials.

Self-lubricating polyether ether ketone PEEK has excellent sliding properties and is suitable for occasions where low friction coefficient and wear resistance are strictly required, especially the sliding grades of PEEK modified with carbon fiber, graphite and PTFE have excellent wear resistance.

In addition to the corrosion resistance of concentrated sulfuric acid, PEEK is insoluble in any solvent and strong acid and alkali, and it is resistant to hydrolysis and has high chemical stability.

Flame retardant polyether ether ketone PEEK has self-extinguishing property, even without any flame retardant, it can reach the 94V-0 level of the UL standard.

Ease of processing Because PEEK has the characteristics of good high temperature fluidity and high thermal decomposition temperature, various processing methods can be used: injection molding, extrusion molding, compression molding and melt spinning.
