Polyether ether ketone or peek is a semi-crystalline polymer with the fame of a high-performance thermoplastic material. Its molecular arrangement is linear and symmetrical, and the intermolecular forces are strong because of the high degree of crystallinity; as a result, it is highly thermally stable and is highly resistant to degradation.
PEEK is commonly offered in industrial grade that addresses specific high-stress/high-temperature applications. These include carbon fiber-reinforced BW PEEK 450 CA30, iron particle-filled BW PEEK 450 FE20, and glass fiber-reinforced BW PEEK 450 FC30. The industrial grade PEEK has not been fully developed and hence gives a picture of raw high performance while the bearing grade has the lubricants to increase the wear resistance of the material. BW GF30 PEEK using glass fiber and BW CF30 PEEK using carbon fiber have higher tensile strength and heat resistance than other conventional thermoplastic materials, and they can be used for load-bearing and high-temperature parts.
Polyether ether ketone commonly abbreviated as PEEK is a semi-crystalline thermoplastic that displays excellent mechanical and thermal characteristics. This is because of its linear structure which has symmetric chains, gives a high density of crystallinity, and has strong intermolecular forces such as hydrogen bonding, van der Walls forces, and π-π interactions. These structural features endow PEEK with high thermal stability and its melting point is about 343 ° C, and PEEK can maintain a continuous working temperature of 250 ° C. This allows PEEK to stand up to its name for being useful in high-performance applications in industries such as medical, aerospace, automotive, and electronics.
PEEK 450 CA30 is an enhanced carbon fiber-reinforced PEEK material that boasts high mechanical properties such as strength and stiffness. The incorporation of carbon fibers enhances the weights’ load-carrying capacity and decreases the coefficient of thermal expansion and high-stress applications that demand dimensional stability. This grade is commonly used in aerospace , automobile and industries where strength and low density materials are needed.
PEEK 450 FE20 is a PEEK filled with iron and provides improved mechanical and thermal conductivity. The addition of iron makes this grade especially ideal for use in situations that require some heat dissipation and enhanced wearing surface. It is widely applied in the production of parts for electric and thermal applications and in conditions that involve friction and wear.
BW PEEK 450 FC30 is a PEEK grade that has glass fibers for reinforcement, which makes it possess high mechanical strength and stability of dimensions. Glass fibers increase its stiffness and it also has low creep factor under load, therefore it is suitable for mechanical load bearing applications.
This grade is mostly applied in aerospace, automobile, and various industries where parts must retain their reliability under adverse conditions.
CN PEEK is also provided in several industrial variants that are further characterized by their special application expectations.
These grades provide a slate of characteristics that makes PEEK cozy and abundantly effective in a broad array of applications in industries.
Unfilled Polyether ether ketone is the most elemental form of the polymer, which thus boasts of the best mechanical strength, and chemical and heat resistance.
It is widely applied in cases, when materials’ purity and great performance characteristics are crucial, for example, in the production of medical instruments, in the semiconductor industry, and in the making of products used in the food industry.
See more The basic grade of the bearing Polyether ether ketone is developed with the specific lubricant to increase the value of wear and friction resistance.
This grade is useful where low friction and wear on sliding and rotating components like bearings, bushings, and wear strips are required. It includes a low coefficient of friction and high resistance to wear making it ideal for use in applications that require a long life span.
BW GF30 PEEK comes with the incorporation of 30% glass fibers making it stronger, stiffer, and dimensionally stable. This grade is useful in applications that necessitate superior mechanical characteristics such as brackets, housings, and support components. The glass fibers also increase the ability to resist deformation under load.
BW CF30 PEEK is a carbon fiber-reinforced grade that has 30% fiber content of carbon and this grade has great mechanical characteristics and a low coefficient of thermal expansion.
This grade is commonly used in places where part strength and stiffness, as well as part thermal stability, are important such as aerospace and automotive industries. It also showed improved electrical conductivity owing to the carbon fibers in addition to better wear endurance.
