Information on PEEK 450G Sheet:
PEEK (Polyetheretherketone) is a high-performance thermoplastic that offers excellent mechanical, thermal, and chemical properties. PEEK sheets are widely used in various industries due to their exceptional characteristics. Here's an overview of PEEK sheet properties, machinability, and applications:
Key properties of 450G PEEK Sheet:
High Temperature Resistance: PEEK sheets can withstand continuous operating temperatures of up to 250-300 degrees Celsius (482-572 degrees Fahrenheit) and maintain their mechanical properties at elevated temperatures.
Mechanical Strength: PEEK exhibits high tensile and flexural strength, making it suitable for applications that require structural integrity under demanding conditions.
Chemical Resistance: PEEK has excellent resistance to a wide range of chemicals, including acids, bases, solvents, and hydrocarbons. This property makes it suitable for applications exposed to harsh chemical environments.
Wear and Abrasion Resistance: PEEK sheets have good resistance to wear and abrasion, which is beneficial in applications that involve sliding or rubbing contact.
Low Friction Coefficient: PEEK has a low coefficient of friction, providing good lubricity and reducing the risk of component wear.
Electrical Insulation: PEEK is an excellent electrical insulator with good dielectric properties, making it suitable for electrical and electronic applications.
Dimensional Stability: PEEK exhibits low creep and excellent dimensional stability, ensuring tight tolerances and precise machining.
PEEK Sheet Machinability:
PEEK is a highly machinable material, but its toughness and high melting temperature require appropriate machining techniques. Some considerations for machining PEEK sheets include:
Cutting Tools: Use sharp tools made from high-speed steel (HSS) or solid carbide. Diamond-coated tools are also suitable for extended tool life.
Cutting Speeds: Optimal cutting speeds for PEEK are typically lower than those used for metals. Higher cutting speeds can cause excessive heat buildup.
Cooling and Lubrication: Cooling the cutting tool and workpiece is important to dissipate heat. Air or water-based coolants/lubricants are commonly used.
Chip Control: Effective chip control is necessary to prevent chip buildup and ensure proper cutting performance. Use appropriate chip breakers or chip evacuation techniques.
Applications of PEEK Sheets:
PEEK sheets find applications in various industries, including:
Aerospace: PEEK is used in aircraft components, such as brackets, bushings, bearings, and structural parts, due to its lightweight, high strength, and resistance to aviation fuels.
Automotive: PEEK is used in automotive applications, including seals, gaskets, connectors, fuel system components, and electrical insulation parts.
Medical: PEEK is widely used in medical devices and implants due to its biocompatibility, sterilization resistance, and high strength. Examples include spinal implants, dental instruments, and surgical instruments.
Electronics: PEEK is used in electrical connectors, insulators, and circuit boards due to its electrical insulation properties and ability to withstand high temperatures.
Oil and Gas: PEEK is employed in oil and gas applications, including seals, bearings, valves, and pump components, due to its chemical resistance and ability to withstand high pressures and temperatures.
These are just a few examples of the numerous applications where PEEK sheets are utilized due to their outstanding properties and machinability.
