PEEK5600LTC Granules
To break through this bottleneck, we innovatively launched PEEK5600LTC – a low-thermal conductivity modified PEEK material designed for thermal insulation needs. On the basis of inheriting the original excellent characteristics of PEEK, this material significantly reduces the thermal conductivity to 0.2W/(m·K) through technological innovation, and reduces the thermal conductivity by nearly 30% compared with pure PEEK5600G, providing a high-performance solution for the field of thermal insulation.
PEEK5600LTC not only have excellent thermal insulation performance, but also excellent weather resistance and processing flexibility. Its particle properties make the injection molding process more efficient and help control production costs; At the same time, the dimensional stability of the molded product is excellent, ensuring assembly accuracy and long-term reliability.
Electronic and electrical field: In 5G base stations, it serves as a high-frequency connector thermal insulation bracket, effectively reducing thermal interference and ensuring the stability of signal transmission. In the field of new energy vehicles, it is used as a thermal insulation layer for battery modules to delay the risk of thermal runaway and improve the safety and life of battery packs.
Aerospace field: used for engine compartment heat shield, achieving 60% weight reduction and 50% improvement of thermal insulation efficiency; In the satellite thermal control system, it effectively blocks the thermal shock of extreme temperature differences on precision instruments and prolongs the service life of satellites.
Industrial manufacturing: In semiconductor manufacturing, it is used as a fixture material to reduce heat conduction; In the sensor housing, external heat is isolated to ensure the accuracy of data collection; At the same time, it is also used in e-cigarette shells, heating plate bases, atomization chambers and other components to provide a safe experience with high temperature resistance and low smoke emission. The high-temperature handle works stably in high-temperature environments thanks to its chemical resistance and flame retardancy.

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.
