Precision CNC machining service: What is PEEK CA30


Characteristics, Advantages, and Disadvantages:

PEEK CA30 offers several key characteristics that make it a preferred material in many industries. Firstly, it has excellent mechanical properties, including high tensile strength, modulus of elasticity, and fatigue resistance. The addition of carbon fiber reinforcement further enhances these properties. Secondly, PEEK CA30 exhibits exceptional thermal stability, with a continuous use temperature of up to 240°C (464°F) and a melting point of around 343°C (649°F). This makes it suitable for applications in high-temperature environments. Additionally, PEEK CA30 has excellent chemical resistance to a wide range of chemicals, including acids, bases, solvents, and fuels. It also possesses good electrical insulation properties.


One of the main advantages of PEEK CA30 is its low coefficient of friction, which results in reduced wear and frictional heat generation. This makes it suitable for applications that involve sliding or rotating components. PEEK CA30 also has good dimensional stability, meaning it maintains its shape and size even under varying temperature and humidity conditions. Furthermore, it is lightweight compared to metals, making it an attractive choice for weight-sensitive applications.


However, PEEK CA30 does have a few limitations. It is relatively expensive compared to other engineering plastics, which can affect its cost-effectiveness for certain applications. It is also challenging to process due to its high melting point and high viscosity, requiring specialized equipment and expertise.

Suitable Applications:

PEEK CA30 finds applications in various industries, including aerospace, automotive, oil and gas, medical, and electronics. Some specific applications include:


1. Aerospace:

PEEK CA30 is used in aircraft components such as structural parts, bearings, seals, and electrical connectors due to its high strength, light weight, and resistance to chemicals and high temperatures.


2. Automotive:

PEEK CA30 is used in automotive applications such as bushings, gears, seals, and electrical connectors due to its excellent wear resistance, low friction, and high temperature resistance.


3. Oil and Gas:

PEEK CA30 is used in oil and gas applications such as seals, valves, pump components, and downhole tools due to its excellent chemical resistance, high strength, and resistance to high pressures and temperatures.


4. Medical:

PEEK CA30 is used in medical devices and implants due to its biocompatibility, sterilizability, and strength. It is commonly used in applications such as spinal implants, dental instruments, and surgical instruments.

Comparison with Other Similar Materials:

When comparing PEEK CA30 with other similar materials, such as metal alloys, PTFE (Polytetrafluoroethylene), and PA66 (Polyamide 66), it is important to consider their specific properties and applications. Here are some examples:


1. Metal Alloys:

Compared to metal alloys, PEEK CA30 offers several advantages. Firstly, PEEK CA30 has a high strength-to-weight ratio, providing comparable strength to metals while being significantly lighter. This makes it suitable for applications that require weight reduction, such as aerospace and automotive components. Secondly, PEEK CA30 has excellent chemical resistance, which is often superior to metals. It can withstand exposure to corrosive chemicals and environments without degradation. Additionally, PEEK CA30 has better fatigue resistance compared to many metals, making it suitable for applications that require repetitive loading. However, metals may still have advantages in terms of cost and specific mechanical properties for certain applications.


2. PTFE (Polytetrafluoroethylene):

PEEK CA30 and PTFE are both high-performance polymers, but they have different characteristics and applications. PTFE is known for its low friction coefficient and excellent non-stick properties. It is commonly used in applications such as bearings, seals, and gaskets. In comparison, PEEK CA30 offers higher mechanical strength, stiffness, and temperature resistance. It is suitable for applications that require both mechanical performance and chemical resistance, such as pump components and electrical connectors.


3. PA66 (Polyamide 66):

PA66 is a widely used engineering thermoplastic known for its high strength, toughness, and excellent wear resistance. It is commonly used in applications such as gears, bearings, and automotive components. When compared to PA66, PEEK CA30 offers superior thermal stability and chemical resistance. It can withstand higher temperatures and harsher chemical environments without degradation. PEEK CA30 also has better dimensional stability and lower moisture absorption compared to PA66. However, PA66 may have advantages in terms of cost-effectiveness and ease of processing.



Processing Considerations:

When processing PEEK CA30, there are a few important points to consider. Firstly, it is crucial to use specialized equipment capable of reaching the high temperatures required for melting and molding PEEK CA30. Injection molding is a common method for processing PEEK CA30. Secondly, proper mold design and cooling systems are essential to ensure dimensional stability and minimize the risk of warping or shrinkage. It is also important to control the processing parameters, such as melt temperature, injection speed, and mold temperature, to achieve optimal mechanical properties and surface finish.

Q: Is PEEK CA30 suitable for food contact applications?

A: PEEK CA30 is not recommended for direct food contact applications due to the potential migration of carbon fibers and additives. However, it can be used in food processing equipment that comes into contact with non-direct food surfaces.


Q: Can PEEK CA30 be recycled?

A: Yes, PEEK CA30 can be recycled through various methods such as mechanical recycling and chemical recycling. However, the recycling process can be complex and may affect the mechanical properties of the recycled material.


Q: What is the shelf life of PEEK CA30?

A: PEEK CA30 has a relatively long shelf life if stored properly. It is recommended to store it in a cool, dry place away from direct sunlight. The typical shelf life is around 2-3 years.


Q: Can PEEK CA30 be machined using conventional methods?

A: PEEK CA30 is a challenging material to machine due to its high melting point and high viscosity. Specialized machining techniques and tools, such as carbide or diamond cutting tools, are recommended for achieving precise and efficient machining results.
