Material Notes:
Murflor® materials are suited to use in applications that require an excellent resistance to chemicals and heating steam. Murflor®’s working range starts at -200°C and can extend to +260°C with no mechanical load. Murflor® also has the lowest dynamic friction coefficient of all thermoplastics.Special Properties:• Best dynamic friction properties of all thermoplastics• No stick/slip effect• Very good anti-adhesion properties• Electrically isolating• Very high resistance to chemicals• Very high resistance to hydrolysis• Very tough, even at low temperatures• Approved for use in the food industry (FDAInformation provided by Murtfeldt Kunststoffe GmbH & Co.
