Filament Gembird TPE Flexible Filament Black:Gembird Black Flexible Filament is made of thermopolymer (TPE), which closely imitates the properties of rubber. You can use it to print 3D objects that will not only look like rubber, they will behave like it too. You can vary your production to make objects with different levels of flexibility and stretchiness. TPE is highly elastic, extremely tear-resistant and has a longer life than other materials.Key Features of Gembird TPE Flexible Filament BlackUnique flexibility and elasticityAbrasion-resistantTear-resistant (excellent adhesion of layers)For use in various 3D printers (1.75mm extruder, melting temperature approx. 230°C, support TPE)Additional information:Material:TPEDiameter:1.75mm (± 0.05mm)Length:approx. 420mProperties:Density at 21.5°C: 0.9g/cm3Melting point: 190-240°CTear strength: 86 kN/mSpool dimensions:Diameter 200mmHeight: 67mmCentral hole: 53mmWeight:1 kg/spool
