Why ZYPEEK for Aerospace

ZYPEEK is increasingly specified across aerospace applications—from wire and cable to cabin systems, propulsion and powertrain, energy storage, avionics and electronics, structural and load-bearing components, to functional and standard hardware. This growing adoption is driven by its exceptional thermal performance, cryogenic resistance, salt spray and chemical resilience, hydrolytic stability, low specific gravity, and inherent flame retardancy—combined with the ability to be precision-molded to extremely tight tolerances.

Why ZYPEEK for Aerospace

High Mechanical Performance, Fatigue Resistance, and Wear Durability

Dimensional Stability

Extended Temperature Range, Superior Flame Retardancy, and Low Smoke Toxicity

Chemical Resistance and Radiation Tolerance

Reliable Electrical Insulation

Lighter, More Compact, Easier to Maintain and Enhanced Processability

Delivering exceptional tensile strength, flexural strength, and creep resistance, ZYPEEK combines stiffness with toughness for outstanding performance under cyclic loading. Its superior wear characteristics and fatigue endurance significantly extend cable service life.

Highly stable under high-temperature, high-pressure steam or hot water conditions with minimal degradation. Low coefficient of thermal expansion, extremely low moisture absorption, and negligible dimensional variation with temperature and humidity fluctuations ensure exceptional dimensional integrity.

Operating continuously from -40°C to 260°C with maintained dimensional stability at temperatures up to 300°C for short-term exposure. Inherently self-extinguishing to UL 94 V-0 without added flame retardants. Extremely low smoke emission. Halogen-free by molecular design. No toxic or corrosive gas generation upon combustion.

Highly resistant to acids, bases, salts, oils, hydrocarbons, and various organic solvents—with the exception of concentrated sulfuric acid. Capable of withstanding high doses of γ and X-ray radiation, suitable for precision components and nuclear energy applications.

Maintaining stable dielectric performance under harsh conditions of high temperature, high voltage, and high humidity. Superior voltage endurance and breakdown resistance, with high dielectric strength and minimal dielectric loss at high frequencies—ideal for wire and cable applications and electronic components.

Lower density enables reduced cable mass and smaller cross-sections—maximizing space utilization, facilitating dense routing, and simplifying installation and maintenance. ZYPEEK can be extruded directly, streamlining manufacturing for greater simplicity and efficiency.

The Future of Aerospace Materials

Fuel efficiency standards, carbon emission regulations, and intense global competition are driving aircraft design to weight-saving extremes—measured gram by gram. To meet ICAO's 2050 net-zero target and the projected delivery of over 40,000 new aircraft in the next two decades, aerospace manufacturers must reduce structural weight, enhance reliability in extreme environments, and shorten final assembly cycles—while maintaining strict cost discipline. Our answer is advanced materials. For two decades, we have deeply invested in aerospace innovation, replacing metals and traditional composites in engines, airframes, and critical components with our high-performance engineering polymers.

Our systems approach—lightweight, fuel and hydraulic fluid resistant, precision moldable—is already proven on multiple commercial aircraft, helicopters, and unmanned aerial vehicles. Working alongside manufacturers, we accelerate the journey from drawing board to blue sky, enabling lower operational emissions, more efficient precision manufacturing, and a clear flight path to next-generation sustainable aviation.

Cabin Systems

Balancing structural load-bearing capability with weight reduction, ZYPEEK achieves UL 94 V-0 flame rating—meeting stringent aircraft fire resistance and low smoke density requirements. This makes it ideal for seat frames, cabin support brackets, overhead bin structures, and oxygen mask housings. Its excellent wear resistance and mechanical strength withstand vibration and creep, while its moldability and aesthetic versatility enhance cabin comfort and safety.

Propulsion & Power Transmission

With high-temperature stability, wear resistance, chemical resilience, and self-lubrication, ZYPEEK delivers weight savings and noise reduction compared to metals—ideal for bearing cages. Its injection moldability enables robust metal-to-polymer bonding for enhanced interface strength in drive shafts. Chemical inertness combined with flame retardancy and high-pressure capability suits rocket high-pressure sealing valves. Superior mechanical properties, wear resistance, and creep resistance extend to engine transfer tubes and structural components—enhancing power system reliability and service life.

Avionics, Electronics & Battery Systems

High strength-to-weight ratio enables stable battery support with mass reduction. Wide temperature capability, anti-aging properties, and tolerance to charge-discharge thermal cycling—combined with excellent insulation and chemical resistance—make ZYPEEK ideal for aircraft battery trays, space-rated batteries, and satellite lithium-ion components. Superior radiation resistance against nuclear exposure, balanced stiffness and toughness, suit connector housings, contact posts, and aerospace receptacles. Electroless plating compatibility enables EMI shielding for enclosure applications. Radar dome performance satisfies avionics requirements for reliability and signal transmission integrity.

Structural & Functional Components

Replacing metals in structural and load-bearing applications, ZYPEEK achieves weight reductions exceeding 30%—deployed in landing gear doors, wing panels, and horizontal stabilizer leading edges—withstanding in-flight mechanical stress and creep. Carbon fiber-reinforced brackets and frames deliver enhanced structural support. In functional and standard hardware applications, ZYPEEK's high heat deflection temperature, corrosion resistance, and wear properties suit aircraft corner brackets; superior insulation and wide-temperature stability enable insulating washers and high-temperature insulating rings. At 60% lighter than metal with corrosion and radiation resistance, it serves as bolts and fasteners. Strong mechanical properties and wear resistance, combined with metal for hybrid stiffness, extend to cable ties, clamps, tubing and fittings, and valve bodies—comprehensively enhancing aircraft performance and reliability.
