Shanghai Chaoju: inner and outer application in aircraft
Aerospace engineers need all kinds of light materials which is flexibility for processing, can cut production cost and bear harsh environment. In more and more aerospace application, PEEK polymer materials have many advantages like hardness, flame retardant, having chemical inertia and be easy to be processed into the parts with minimal tolerance.
Lighter in flight and higher fuel efficiency.
▲In comparison with metal, it can cut weight as high as 70% and possess the same strength and hardness.
High efficiency production
▲Injection production can let engineer to simplify and standardize parts, and compose many parts into one functional part.
▲Fewer parts and more convenient for installment. To speed up the installment and cut the cost of system.
Reliable quality
▲In 260℃, heating and aging for more than 5000 hours without force, it won’t lose tensile strength property.
▲It has dimensional stability, creep resistance, anti-fatigue and moisture resistance.
▲Having tolerance to jet fuel, hydraulic oil, deicing solution, insecticide, cleaning fluid, fire extinguishing chemicals, water, salt and steam.
▲The fire protection grade is UL94 V-0. It has characteristics like low smoke, low poisonous gas emission and so on.
It has replaced metal, traditional compound materials and other plastics successfully.
