How To Know About The PEEK Material Machining And Properties
The polyetheretherketone, AKA PEEK, bears a broad temperature range. In addition, the material benefits from being a lightweight polymer. Such conditions make the PEEK a suitable choice in engineering applications. At Creatingway, we use PEEK to achieve performance and demanding requests. Not only does it solve resistance but also long-term pressure. We obtain superb resistance along with tensile strength. Those unique qualities aid in industries such as oil and gas. The industries can easily leverage the benefits that the PEEK material machining services offer.
What is PEEK material?
The PEEK is a type of thermoplastic polymer. The material is colorless and organic. Moreover, It Has both mechanical and chemical aspects that suit a wide range of engineering use. The PEEK belongs to a PAEK family of polymers, i.e., polyaryletherketone. Therefore, we manufacture the material via step-growth polymerization. Even though it’s more expensive than other polymers, it offers superior performance in various dimensions. The unique qualities are; desirable excellent wear and abrasion resistance.
What are The Properties of PEEK Material?
high-temperature Resistance
Thermoplastic material makes PEEK to be highly resistant to temperatures. The polymer can withstand a high glass transition temperature of 143 degrees Celsius. It also can maintain high strength. The strength is due to the melting point of 334 degrees Celsius. Short-term temperatures of 300 degrees Celsius are tolerable. That’s why we use PEEK materials where heat resistance is necessary.
Good Mechanical Properties
In terms of fatigue resistance, PEEK is the best. We obtain superb results when combining fatigue resistance and mechanical strength with products. Hence, it increases the durability and lifespan of goods produced. Thus, Making PEEK dependable in making desirable items for our customers.
Wear Resistance and Lubricity
The polymer possesses proper wear resistance and great sliding traits. We use the sliding property to reduce the coefficient of friction greatly. Hence, it allows specific parts to work without lubricants rendering it economical. The wear resistance increases the lifespan of products
Chemical Resistance
PEEK is chemical Resistance towards;
- Chemicals
- Acids
- Alkalis
- Concentrated sulfuric acid
- Organic solvents and inorganic solvents
The polymer also has corrosion resistance. Chemical properties, material composition, and morphology determine the Resistance of PEEK.
Flame resistance
Being a linear aromatic semi-crystalline polymer, it entails flame retardant aspects. In addition, we have performed several tests on the PEEK. Such tests are like;
- UL 94 test
- Vertical burn test
- Self-extinguishing time test
The results show a burn rate of V-0, thus the highest flame retardancy level. Hence, it helps us in the making of materials requiring heat resistance.
Peel Resistance
The peel resistance in PEEK is very high. We can use this trait in the making of;
- Cable insulation
- Very thinly wrapped wire
- Electromagnetic wire
Such products can endure harsh areas and conditions.
Irradiation Resistance
PEEK materials can resist gamma radiation strongly. Thus, it helps in retaining the original performance of products.
Hydrolysis Resistance
The polymer isn’t chemically affected by high-pressure water vapor and water. Thus, products made from PEEK maintain superb properties. Hence, it increases the lifespan even when subjected to extreme conditions. The conditions may be high-pressure water and high temperatures.
What’s The Using of PEEK Material Machining?
Medical Industry
PEEK contains biocompatible properties, which are helpful in the medical field. Some of the uses may be
- Dental healing caps.
- Different drug delivery systems
- Spiked washers
- Trauma fixation device
- Spinal fusion devices
- Surgical instruments
Additionally, the anti- corrosiveness of PEEK makes it useful in medical implants. Thus, it helps in improving the medical field greatly.
Aerospace Industry
PEEK is compatible with traits regarding aerospace parts. Such traits are like;
- Ultra-high vacuum applications
- Thermal conductivity
- Radiation resistance
- Chemical resistance
This unique quality aids in the making of aerospace parts. The PEEK material machining parts also entail high tensile strength. Hence, the end product is essential for aerodynamics purposes.
Automotive Industry
The superior weight-to-strength ratio favors the polymer greatly. With that ratio, we use PEEK material machining in the making of;
- Bearing
- Different types of rings
- Engine blocks of racing cars
- The seal and brake components of vehicles
Furthermore, PEEK being lighter than metals improves the fuel efficiency of vehicles produced. The heat and chemical resistance also aid the automobile industry. Other properties like anti-magnetic and dielectric are essential in vehicle production. Due to the non-flammability of PEEK, there isn’t out-gassing.
Wire and Cable Insulation/Electronic Applications
We use PEEK fasteners in the making of electronic devices like;
- Laptops
- Gaming devices
- Mobile phones
Properties like; lightweight, cost-effective and non-conducting make it possible.
In conclusion, The PEEK has proven to be the material of choice. Its application applies across the entire engineering platform. It has unique properties that differ from other polymers. These properties are; mechanical, chemical, electrical, and thermal. We use machining to obtain PEEK in different forms. Injection molding and 3D printing are also alternative methods.
