|PEEK ball valve seat|
PEEK is a high-temperature , high-performance specialty engineering thermoplastics . It has good mechanical
properties and resistance to chemicals,abrasion -resistant properties , hydrolysis , etc. ; its light weight,
selflubricatingproperties , due to the very good processing properties, can be filled with carbon fiber,
such as molybdenum disulfide to further improve the lubricity and mechanical strength. PEEK plastic broad application space comes to high-tech industries in aviation, machinery, electronics, chemical, automotive , etc.,
may be required for the manufacture of high mechanical parts such as gears, bearings ,piston rings, support
rings,seals ( letter ), valves, wear rings. High performance PEEK material is mainly manifested in the following aspects :
Note: If you need any products of ours, please kindly contact with us directly by following contaction . Then we can reply you faster and easy . Thanks
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

|We offer the most complete line of valve seats for various valves across many industries in PTFE,RPTFE,TFM,PCTFE,PEEK,NYLON,etc.
PEEK has a good comprehensive property in resistance of high temperature,chemical and wear. PEEK valve seats has a long term working temperature around 260and melts around 343℃. It is very suitable for that kind of bad working conditions of high temperature and high pressure. Due to this advantage,PEEK valve seats are be widely used in floating or fixed ball valve.
According to the actual working conditions,PEEK valve seat materials include:
Standard and custom sizes are all welcomed.
