PEEK Gear and PEEK Seal
PEEK Polymer | Gear Grade
It's time to replace metal gears. PolyEtherEtherKetone (PEEK) Maintains wear resistance and
mechanical strength up to 480°F continuous use. PEEK is the performance material of choice
for aggressive environments such as high temperatures, wet processes, and heavy loads.
The main trends in the industry are: improving performance and efficiency, reducing weight
and achieving miniaturization while reducing costs, gear applications need to find new
materials to replace existing metal materials or perfect typical polymeric solutions to meet
future systems High demands on performance.
PEEK gears are widely used because of their light weight, wear resistance, self-lubrication,
low noise, corrosion resistance, high temperature resistance and other characteristics.
Junhua ChinaPEEK can provide customers with the determination and selection of gear raw
materials, surveying and drawing, gear design, mold opening and injection molding, sample
processing, and mass production, as well as application scenarios, working conditions and
PEEK gear solutions.
The main trend in the industry today is to increase performance and efficiency, reduce weight and achieve miniaturization while reducing costs. In gear applications, engineers are looking for new materials to replace existing metallic materials, or to perfect typical polymeric solutions to meet the high performance demands of future systems. Because different types of loads are always sent at the same time, the gears need to meet multiple complex needs. The proper operation of gears depends on good friction and mechanical properties, performance against aggressive media, durability and heat resistance, and dimensional accuracy.
Polyetheretherketone (PEEK) is a new type of high-performance special engineering plastics, which has been produced and used for more than 30 years.
PEEK Seal
The PEEK polymer and composite high-performance plastic parts produced by the company have been widely used in various links such as downhole measurement, oil exploration, petrochemical plant production and transportation.

PEEK Seal
Jiangsu Junhua Special Plastics has cooperated with Saudi Arabia, PetroChina, Sinopec,
University of Petroleum, Xi'an and other customers to produce PEEK support sealing ring,
PEEK front and rear plugs, PEEK insulating ring, PEEK polar plate, PEEK insulating wire,
PEEK spacer ring, PEEK retaining ring, PEEK Wear-resistant shaft sleeves and other
products.
High-performance plastic parts such as high-temperature wear-resistant bushings, insulating
rings, and front and rear plugs made of PEEK and its modified composite materials can
replace traditional materials such as copper alloys, stainless steel, PTFE, ordinary
engineering plastics, and graphite. Oil logging and production equipment have strict
technical requirements for parts such as wear resistance, high temperature resistance, high
strength, oil- lubrication, acid-base corrosion, and high reliability, which can reduce
operating costs and help equipment to continuously operate at the highest production
capacity. stable production.

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.
