With the improvement and upgrading of equipment, in order to meet the needs of the new era, the comprehensive performance and lightweight of equipment have become prominent. Due to its low density, high strength and corrosion resistance, PEEK is used in the production of portable equipment parts, which has made progress and breakthroughs in reducing weight and improving strength, and has increased the service life of the equipment. Therefore, PEEK materials have broad application prospects in the parts of night vision devices, such as handheld night vision devices, helmet-mounted night vision devices, etc., which use a large number of PEEK material parts.
PEEK material is actually used in the parts of infrared and thermal imaging night vision devices. Its biggest features are:
01. It is lightweight and
easy to carry for a long time, reducing the weight of individual equipment.
02. High mechanical properties
PEEK is the top material of the engineering plastic pyramid. Its strength, hardness and rigidity are superior to other common engineering plastics.
03. High physical properties
PEEK material has the characteristics of wear resistance, high temperature resistance, dimensional stability, etc., which makes PEEK material widely used in military equipment and can be used normally in special environments.
04. Stable chemical properties
PEEK material has excellent corrosion resistance and relatively stable dimensions, and will not affect the performance of the equipment even in bad weather.
What is PEEK？
PEEK and its modified composite materials show excellent performance under high temperature and high humidity conditions. PEEK have excellent chemical corrosion resistance, self-lubricating, and wear-resistant properties, so it has become the most ideal material to replace copper alloys and ordinary rubber. Compared with them, PEEK has longer service life which can reduce equipment operating costs, improve equipment operating reliability.
High Temperature Performance
PEEK’s performance can remain stable in the temperature range from -196°C to 260°C. Under extreme working conditions, it can withstand 300″C for a short time. The performance of PEEK is still reliable even in high temperatures of several kilometers underground work environment.
High Strength and Wear Resistance
Compared with other plastics, PEEK is resistant to compression, impact and also have good fatigue resistance. PEEK is durable in mechanical equipment and wear-resistant environments.
Double the Service Life
PEEK sealing solutions can improve the part service life. Some domestic chemical companies use the PEEK5600FE20 polytetrafluoroethylene modified material designed by JUNHUA PEEK to replace the original material, the service life of the wear parts can even be extended by 1.3-3 times.
Corrosion Resistance
PEEK is chemically inert, and has no reaction to most acids, oils, greases and all other organic and inorganic solvents or enzymes, and can still maintain good strength and dimensional stability.
Self-lubricating
PEEK has low friction coefficient, low running resistance, can be used without oil in some working conditions. The equipment is cleaner, thus improving process reliability, improving energy efficiency and saving costs.
More dom in Design
Injection molds can be used for rapid injection molding of large quantities of complex special-shaped parts, and the cost is low compared to machining.

Common PEEK Grades and Properties
1. PEEK5600G (brown-gray/khaki) is made from pure polyetheretherketone resin and offers the best toughness and impact resistance of all PEEK grades. Pure PEEK can be sterilized using convenient methods (steam, dry heat, ethanol, and gamma-rays), and the raw materials used in its manufacture comply with EU and US FDA food compatibility regulations. These characteristics make it widely used in the medical, pharmaceutical, and food processing industries.
2. PEEK5600LF30 (black) The addition of PTFE, graphite, and carbon fiber makes PEEK5600LF30 a bearing-grade plastic. Its superior tribological properties (low coefficient of friction, wear resistance, and high peak pressure limit) make it an ideal material for this class of friction applications.
3. PEEK5600GF30 (Brown-Gray): This material is a reinforced grade of plastic filled with 30% glass fiber. It offers superior rigidity, creep resistance, and dimensional stability compared to PEEK, making it ideal for structural parts. It can withstand fixed loads for extended periods at high temperatures. If PEEK5600GF30 is used as a sliding component, its suitability should be carefully verified, as the glass fiber can scratch mating surfaces.
4. PEEK5600CF30 (Black): This material is reinforced with 30% carbon fiber. It offers superior mechanical properties (higher elastic modulus, mechanical strength, and creep resistance) and wear resistance compared to PEEK5600GF30. Furthermore, carbon fiber-reinforced plastic has 3.5 times the thermal conductivity of unreinforced PEEK, dissipating heat more quickly from the bearing surface.
