Junhua PEEK: Aircraft interior and exterior applications

Aerospace engineers need a variety of lightweight materials that can be flexibly processed, reduce manufacturing costs, and withstand harsh environments. In more and more aerospace applications, PEEK polymer materials are used because of their exceptional strength, chemical inertness, flame retardancy, and easy processing into parts with extremely small tolerances.

Flying lighter and more fuel efficient

▲Compared with metal, it can reduce weight by up to 70%, while having the same strength and rigidity;

Efficient production

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

▲Fewer parts and easier installation, which speeds up assembly and reduces system costs.

Reliable quality

▲Under 260℃ (500℉) conditions, no tensile strength performance loss after more than 5000 hours of non-stress heating aging;

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

▲Tolerance to aviation fuel, hydraulic oil, de-icing solution, pesticides, cleaning fluids, fire-fighting chemicals, water, salt and steam;

▲The fire protection grade is UL94 V-0, with the characteristics of low smoke and low toxic gas emission.

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

PEEK cable ties

Used to bundle cables and secure them to the machine body. The low moisture absorption of PEEK polymer ensures that the cable bundle remains dimensionally stable, thus not expanding and damaging the insulation of the wires.

PEEK composite fasteners

Aircraft structures using lightweight composite materials are becoming the standard for new aircraft development. They are made into truly lightweight restraining systems, bolts, nuts, plugs and brackets. They have the advantages of fatigue resistance, high strength and corrosion resistance.

PEEK radome

PEEK polymer material can be made into high-dimensional precision radar antenna cover by injection molding, which has the following advantages:

▲Excellent rainproof performance

▲High strength

▲Compared with other radar antenna cover materials, its electrical performance is more stable in extreme temperature environments.
