There is no warranty expressed or implied and the final determination of material suitability is the responsibility of the user.

C = Fair – Moderate Effect, not recommended for continuous use. The PEKK formulations are expressed by the ratio of Terephthaloyl (T) to Isophthaloyl (I) moieties used during the synthesis that created the polymer. Like all chemicals, PEEK and other PAEK materials consist of specific building blocks of elemental molecules. PEEK has a long lifetime in the harshest environments. C = Fair -- Moderate Effect, not recommended for continuous … PEEK is often used as a lightweight substitute for metal parts in chemical-processing applications. * The resistance ratings given for Ertalon®/Nylatron® and Ketron® PEEK are in first instance valid for the unreinforced grades.

Chemical Name Acronyms. Synthesis. D = Severe Effect, not recommended for ANY use.

PEKK is synthesized in various formulations with individually unique properties. Most notably aerospace, automotive and chemical sectors prefer PEEK because of its strength, durability and chemical resistance. PEEK polymers are obtained by step-growth polymerization by the dialkylation of bisphenolate salts.

However, PEEK can operate at higher temperatures and retains its excellent mechanical properties at continuous-use temperatures up to 240 °C (464 °F), allowing it to replace metal in severe end-use environments. The chemical compatibility of LDPE and HDPE on this chart is tested at 20°C: and 50°C: for 7 days and 30 days (if applicable) with constant exposure.

Wear- and Chemical-Resistant PEEK Sheets and Bars. “CP” PEEK Material Chemical Compatibility Chart Ratings: A = Excellent B = Good – Minor Effect, slight corrosion or discoloration.


This chemical res is tance chart is to be used as a guide only. N/A = Information Not Available This feature along with its exceptional heat stability makes PEEK particularly suited for critical applications in aerospace, automotive, chemical processing, healthcare, oil and gas, electrical, electronic, energy, … Chemical Resistance Chart PN 41-6018/rev.C January 2010. ultem ± pei (poly-ether-imide) chemical resistance chart key* code explanation resistance temperature° f 1 excellent resistance to chemical attacka 70° b 100° 2 good resistance to chemical attack -c 120° may have slight swelling or loss of propertiesd 140° e 150° 3 marginal resistance to chemical attack -f 170° may crack, swell or dissolve.
The different names indicate the quantity/order of Ether and Ketone … Kepstan® is a Polyetherketoneketone (PEKK) CoPolymer and is in the family of Poly Aryl Ether Ketone (PAEK) polymers. With superior wear resistance in repetitive processes, these sheets and bars resist wear caused by abrasion. Chemical Compatibility Plastic Material Chart for PA66, PEEK, PPS, PVDF and POM PA66 = polyamide 66 PEEK = polyetheretherketone PPS€€ = polyphenylene sulphide PVDF = Polyvinylidene fluoride POM = polyoximethylene acetal Ratings -- Chemical Effect A = Excellent. Hinweis: Die chemische Beständigkeit von jedem Polymer wird hauptsächlich durch die chemische Struktur des Materials und die Stärke des schwächsten Glieds in dieser spezifischen Struktur bestimmt. KetaSpire® PEEK (polyetheretherketone) offers the best combination of fatigue resistance and chemical resistance, which is similar to PPS (polyphenylene sulfide). UD : Undiluted (technically pure chemical) SS : Saturated aqueous solution (at 23°C) CA : As commercially available Temperature (°C): RT : Room temperature (15 – 25 °C). The crystalline nature of PEEK contributes to its outstanding properties.

Even when used at 260°C for 5000 hours, the strength is almost the same as in the initial state and excellent in thermal stability. LDPE / HDPE Resistance Chart by Chemical.

Print ThermaX™ PEEK parts with Gearbox™ HT2 High-Temp 3D Printer. It exhibits excellent resistance to a wide range of … All PAEK materials are well known for chemical resistance, high-temperature resistance, and low wear-and-tear.
