GEHR PEEK®

Polyetheretherketon besitzt eine sehrhohe Dauergebrauchstemperatur (ca.+260 °C), Steifigkeit und Härte, eineeinzigartig hohe Zug- und Biegewech-selfestigkeit (hohe Zähigkeit und Ermü-dungsfestigkeit), eine hohe Wärmeform-beständigkeit und eine sehr guteChemikalienbeständigkeit. Es besitztsehr gute dielektrische Eigenschaftenbis +260 °C und ist beständig gegenenergiereiche Strahlung (selbst UV-Strahlen führen nur zu einer leichtenGelbfärbung des Materials). PEEK istselbstverlöschend gemäß UL 94.

Eigenschaften:• sehr hohe Festigkeit und Steifigkeit• sehr hohe Zähigkeit (auch bei Kälte)• sehr hohe Temperaturbeständigkeit• sehr hohe Wärmeformbeständigkeit• sehr hohe Kriechfestigkeit• sehr hohe Dimensionsstabilität• sehr hohe Beständigkeit gegen ß-,

γ-, Röntgen- und Infrarotstrahlen• hohe Hydrolysebeständigkeit• relativ geringe Kerbschlagzähigkeit• geringe Beständigkeit gegen Aceton

Anwendungsbeispiele:Kolbendichtringe, Gleitlager, Ventilsitze,Lagerschalen, Zahnräder, Pumpenlauf-räder, Steckverbinder und Fittings in derChromatographie, Säulenpackungen,Dichtungsringe, Halbleiterindustrie.

GEHR PEEK-30GF®

verstärkt mit 30% Glasfaser.

GEHR PEEK®

Polyetheretherketone can be used atvery high temperatures (about +260 °C)and it shows an extraordinary mechanicalstrength, toughness, hardness, flexuralstrength, torsional strength. PEEK exhibitsexcellent chemical resistance, very gooddielectric properties up to +260 °C anda very good resistance to all kinds ofradiation (even ultraviolet rays only leadto a slight yellow discolouration of itsself-extinguishing properties accordingto UL 94.

Properties:• very high mechanical strength• very high rigidity (also at low tempera-

ture)• very high thermal stability• very high creep resistance• very high dimensional stability• very high radiation resistance• very high hydrolysis resistance• relatively low notch impact-strength• low resistance to acetone

Application:Bearing shells, piston rings, valve seats,gears, seals, aviation, cog-wheels, pumpvanes, fittings, plug connectors for the-chromatography, wafer carriers, semi-conductor industry.

GEHR PEEK-mod®

Reinforced with 10% of each PTFE,graphite and carbonfibre.Very good friction and wear and tearproperties.

GEHR PEEK®

Le polyétheréthercétone possède unetrès haute température d’utilisation encontinu (env. +260 °C), une solidité etune dureté élevées, une résistanceélevée à la traction et à la flexion alternéeunique en son genre, (ténacité etrésistance à la fatigue élevées), unegrande résistance à la déformationthermique et une très bonne stabilitéchimique. Il possède de très bonnespropriétés diélectriques jusqu’à+260 °C et résiste au rayonnement àhaute énergie (même des rayons UV neprovoquent qu’un léger jaunissement dumatériau). Le PEEK est auto-extinguibleselon UL 94.

Propriétés :• Solidité et rigidité très élevées• Ténacité très élevée (même au froid)• Résistance thermique très élevée• Résistance très élevée à la

déformation thermique• Résistance au fluage très élevée• Très grande stabilité dimensionnelle• Résistance très élevée aux rayons β,

g, X et infrarouges• Résistance élevée à l’hydrolyse• Résistance aux chocs relativement

faible• Faible résistance à l’acétone

Exemples d’application :Segments de pistons, paliers lisses,sièges de soupapes, coquilles depaliers, roues dentées, roues mobilesde pompes, connecteurs à fiches etgarnitures en chromatographie, enro-bages de colonnes, bagues d’étanchéité,semi-conducteur industrie.

GEHR PEEK-mod®

Renforcé jusqu’à 10% au PTFE, augraphite et aux fibres de carbone.Très bon comportement au frottementdynamique et à l’usure par frottement.

Symbolism for the description of the chemical resistance + = resistant (only small changes of the weight, dimensions and properties. According our experiences there is no permanent damage expect).

o = partly resistant (medium changes of the properties. At longer contact time there are permanent damages recommended e.g. degradation of the macro molecular structure).

- = non resistant (strong and permanent degradation in short contact time e.g. stress cracking).

= not tested (no tests were done, no recommendations are possible).

The figures indicated here are approximate values. They may be affected by the temperature, operating time, concentration and stress level of the component involved, by mechanical loads, etc., and the user is not released therefore from the obligation of performing checks and trials of his own. The values indicated here have been compiled on the bases of current experiences and findings. Any legally binding guarantee of certain properties, or any suitability for a specific application cannot be inferred from the present data.
