Model No.: PEEK LF sheet
PEEK LF Carbon Fiber Graphite PTFE Sheet Block
1 . Temperature
PEEK has a high glass transition temperature and melting point (334 °C), which is one of the reasons that it requires heat resistance can reliably use the application . Its load thermal deformation temperature up to 316 °C, continuous use temperature of 260 °C.
2 Mechanical properties
PEEK is both toughness and rigidity and balance of plastics. Particularly its excellent resistance to alternating stress fatigue is the most outstanding of all plastics , can be comparable with the alloy material.
PEEK has outstanding sliding properties in all plastic , suitable for demanding low coefficient of friction and abrasion purposes. Especially carbon fiber, graphite certain percentage of each hybrid modified PEEK better self-lubricating properties .
4 chemical resistance ( corrosion )
PEEK has excellent chemical resistance, in the usual chemicals that can dissolve or destroy it only concentrated sulfuric acid , and its resistance to corrosion and nickel steel similar.
5 flame retardant
PEEK polymer is very stable , 1.45mm thick sample , without any flame retardant can achieve the highest standards .
6 peel resistance
PEEK excellent peeling resistance , it can be made of wire or coated with a thin wire , and can be used in harsh conditions .
7 fatigue resistance
PEEK has the best resistance to fatigue in all resin.
8 radiation resistance
The ability of strong resistance to γ radiation over the best general-purpose polystyrene resins radiation
resistance . You can still maintain γ radiation dose made up 1100Mrad good insulating ability when high performance wire .
9 hydrolysis resistance
PEEK and its composites from chemical effects of water and high-pressure steam , products made of this
material at high temperature and pressure water can still maintain excellent properties of continuous use
