The Zurcon Z13 material developed by Trelleborg, Stuttgart, is a 60 Shore D hard, thermoplastic polyurethane that combines very good mechanical and elastic material properties.This makes it suitable for higher pressures and high temperatures without losing its strength.The new piston seal has proven its performance in applications with HFC pressure fluids.(Image: Trelleborg)The properties of the new piston seal in terms of sealing effect and wear in applications with HFC pressure fluids were documented in comparative tests.Due to their composition of water and glycol, the flame-resistant fluids have a significantly higher ignition temperature and are therefore suitable for applications with an increased risk of fire.However, the variable water content of around 35 to 50 percent influences the tribological properties.HFC fluids are used at temperatures from -20 °C to 60 °C in applications such as mining, foundry technology and offshore in the oil and gas industry.In applications with high dynamics, such as compensation cylinders, the sealing system is subjected to extreme stress due to long strokes.This places the highest demands on the wear resistance and dimensional accuracy of the sealing system.The company has now examined PTFE materials with various fillers as well as seals made from polyethylene and polyurethane.Eight sealing systems of the same design were subjected to extensive tests on a wear test bench and a test bench for measuring frictional forces.The TPU 60 Shore D Zurcon Z13 achieved the best results.While seals made from other material groups showed significant wear after just 200,000 load changes, seals made from this material with identical sealing geometry showed no leakage and no other abnormalities even after one million load changes.The Glyd-Ring-D high-pressure piston seals are extremely hard with very good elasticity and tensile strength at the same time.I agree to being informed by plastverarbeiter via email about magazines, online offers, products, events and downloads from the industry media network.I also agree to the evaluation of my use of the newsletter to optimize the product range.I can revoke this consent at any time with effect for the future by unsubscribing from the newsletter.I have read and acknowledged the data protection information.By registering, I accept the terms of use of the portals in the industry media network.I have taken note of the data protection declaration.Trelleborg Sealing Solutions Germany GmbHWith the smart function kit for pressing and joining, Bosch Rexroth, Lohr, offers a ready-to-use, mechatronic package.The modular system of mechanics, electronics and software simplifies and accelerates product selection and configuration as well as commissioning.Read more...Raw material prices are rising and manufacturers are complaining about the generally poor supply situation.The corona pandemic mercilessly exposes the dependency of entire supply chains.You can find out the fatal consequences in our constantly updated ticker.Read more...After two years of construction, KraussMaffei has opened a new plant in Laatzen near Hanover.In the future, extrusion systems and recycling technologies will be implemented in the continuously networked production environment.Read more...SCHOTT Pharma AG & Co.
