PEEK (polyether ether ketene) materials, high continuous use temperature (about +260 ℃), alohas a very high stiffness and hardness, as well as unique high tensile strength and fatigue strength out (high toughness and fatigue strength). In addition the heat deformation properties and chemical stability is not superb. When the temperature reaches 260 ℃ until the material has excellent dielectric properties and resistance to energy radiation exposure (UV radiation only a slight yellowing of the material). Since the flame can be extinguished.
Advantages:
· High strength and stiffness
· High toughness (also applies to low-temperature conditions)
· High temperature stability
· High heat deformation capacity is not
· A high creep strength
· High dimensional stability
· High resistance to roentgen rays and infrared capabilities
· High resistance to hydrolysis (18 atom, 280 ℃) Disadvantages:
· Notch impact toughness of the general
· In general resistance to acetone
Application areas:
Piston seals, bearings, valve seats, bearing sleeve, cog, turbo pump, plug connections, seals.
