The Peek Rod You Know About
PEEK rod introduction:
1. Basic information:
Polyether ether ketone rod is a high-performance thermoplastic special engineering plastic rod extruded from PEEK raw material. Its density is generally around 1.45g/cm ³.
2. Performance characteristics:
-Excellent heat resistance: The glass transition temperature can reach 151 ° C and the melting point is 348 ° C. After being filled with GF (glass fiber) or CF (carbon fiber), the heat deformation temperature can reach 326 ° C or above. The long-term use temperature recognized by UL in the United States is 260 ° C. It can still maintain good performance in high temperature environments and has significant advantages compared to other high temperature resistant plastics.
-Excellent mechanical performance: It is a material that combines toughness and rigidity perfectly, with strength and fatigue resistance even better than some metal and alloy materials. The bending strength at 200 ° C is about 24MPa, and the bending strength and compressive strength at 250 ° C are still 12-13MPa.
-Good flame retardancy and low smoke emission: It has flame retardant properties without the need to add other flame retardant components. A sample with a thickness of 1.45mm can meet the UL-94V0 standard, and the smoke emission is significantly lower than other types of resins.
-Excellent chemical resistance: In addition to being corroded by strong oxidizing acids such as concentrated sulfuric acid, it has chemical resistance similar to PTFE resin and can fully retain its mechanical properties in various chemical reagents, making it an extremely excellent corrosion-resistant material.
-Excellent hydrolysis resistance: It can maintain good mechanical properties even after long-term immersion in high-temperature steam and hot water, making it the most hydrolysis resistant resin among all.
-Good dimensional stability: With extremely low water absorption and linear thermal expansion coefficient, the product has excellent dimensional stability in various application environments.
-Excellent electrical and insulation performance: It still has excellent insulation and stable electrical performance in environments such as high temperature, high voltage, high speed, and high humidity.
-Strong radiation resistance and weather resistance: It has excellent resistance to various types of radiation, can withstand high doses of gamma rays and maintain its various characteristics, and can be applied to various harsh environments.
-High purity, low volatility, and non-toxic: PEEK rod resin itself is non-toxic, its molecular structure is very stable, it is not easy to produce volatiles, and it also has radiation resistance. The purified high-purity resin is an excellent biomedical material.
Application of PEEK rod:
-In the aerospace field, it can replace aluminum and other metal materials to manufacture various aircraft components, such as wings, fuselage structural components, engine components, etc. By utilizing its excellent flame retardant properties, it can also be used to manufacture internal components of aircraft to reduce the degree of danger in the event of a fire.
-In the field of mechanical industry: Due to its high temperature resistance, corrosion resistance, fatigue resistance, friction resistance and other characteristics, PEEK rods are widely used in many parts of equipment both domestically and internationally, such as bearings, piston rings, reciprocating gas compressor valve plates, gears, support rings, sealing rings (seals), valve plates, wear-resistant rings, etc.
-In the field of energy and power: PEEK rods have high temperature resistance, resistance to hydrolysis, and radiation resistance, so the wire and cable coil skeletons made from them have been successfully applied in nuclear power plants and can also be used to manufacture related components in other energy fields.
-In the field of electronics and electrical appliances, the performance is stable over a wide temperature range, and the components made from it can withstand high temperature environments such as heat welding treatment. In the semiconductor industry, it is commonly used to manufacture wafer carriers, electronic insulation films, and various connecting devices.
-Medical field: Widely used in the medical industry, such as in the manufacture of PEEK rods for lumbar non fusion surgery, which can replace traditional fusion surgery, preserve spinal movement function, and reduce the risk of postoperative stiffness and adjacent segment degeneration; It can also be used to manufacture components for medical devices, such as surgical instruments, implants, etc.
-In the field of petrochemicals, it can be used to manufacture probes with special geometric dimensions involved in petroleum exploration and extraction machinery, as well as various chemical pump bodies, valve components, seals, etc.
-In the field of food processing, the raw material composition for manufacturing PEEK rods complies with the EU and US FDA regulations on food adaptability. Its good chemical resistance and hydrolysis resistance make it suitable for related components in food processing lines.
