A new type of rocket high-pressure sealing valve core

PEEK polymers powered the successful launch of a new launch vehicle with the highest thrust to date. This new rocket meets the carrying capacity requirements of major aerospace projects and will provide high-performance vehicle components for major aerospace projects, including the manned space station project, the third phase of the lunar exploration program, and the Mars exploration program.

PEEK applications in interior and exterior aircraft

Aerospace engineers require a variety of lightweight materials that offer flexible processing, reduced manufacturing costs, and resistance to harsh environments. PEEK polymers are increasingly being used in aerospace applications due to their exceptional strength, chemical inertness, flame retardancy, and ease of processing into components with extremely tight tolerances.

Lighter Flight and Higher Fuel Efficiency

▲ Up to 70% weight reduction compared to metal while maintaining the same strength and stiffness;

Efficient Production

▲ Injection molding allows engineers to simplify and standardize parts and combine multiple parts into a single functional component;

▲ Fewer parts and easier assembly speed up assembly and reduce system costs.

Reliable Quality

▲ No loss of tensile strength after unstressed heat aging for over 5,000 hours at 260°C (500°F);

▲ Dimensionally stable with excellent creep, fatigue, and moisture resistance;

▲ Resistant to aviation fuel, hydraulic oil, de-icing solutions, insecticides, cleaning fluids, fire-fighting chemicals, water, salt, and steam;

▲ UL94 V-0 fire rating with low smoke and toxic gas emissions.

It has successfully replaced metal, traditional composites, and other plastics.

PEEK Cable Ties

Used for bundling cables and securing them to the airframe. The low moisture absorption of PEEK polymer ensures dimensionally stable cables, preventing expansion and damage to wire insulation.

PEEK Composite Fasteners

Lightweight composite materials are becoming the norm in new aircraft development. They are used to create truly lightweight restraint systems, bolts, nuts, inserts, and brackets. They offer fatigue resistance, high strength, and corrosion resistance.

PEEK Radomes

PEEK polymer can be injection molded into high-dimensionally precise radomes, offering the following advantages:

▲ Excellent rainproofing

▲ High strength

▲ More stable electrical properties under extreme temperature conditions compared to other radome materials.

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 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.
