PolyMax™ PC-FR, creation from Covestro’s Makrolon® family, could achieve V0 performance in the UL94 flame retardancy test and displays excellent toughness, strength and heat resistance. This filament opens new applications in the automotive, railway and aerospace industries. Has PolyMax™ PC-FR been tested by a third-party? Yes, PolyMax™ PC-FR has been tested by SGS-CSTC Standards Technical Services Co., Ldt. Test Method:IEC 60695-11-10:2013/Cor.1:2014 Method B Result:Classification: V-0 Full test report here. Printing, Drying and Annealing Settings? Printing Temperature: 250˚C - 270˚CBed Temperature: 90˚C - 105˚CChamber Temperature: 90˚C - 100˚CPrinting Speed: 30mm/s - 50mm/sFan: OFFDirect Drive:Retraction Distance: 1mmRetraction Speed: 20mm/sIndirect Drive:Retraction Distance: 3mmRetraction Speed: 40mm/sDrying Settings: 75˚C for 6h(Only if the material has absorbed moisture)Annealing Settings: 90˚ for 2h Does the FR affect the mechanical properties? Yes, the FR additive will make the material less ductile which means a higher tensile strength and Young's modulus (more rigid). However the PC will maintain its great impact and high heat resistance. More information in the technical data sheet below.
