Technical Datasheet | Supplied by Polymaker

PolyMaker™ PC-PBT by Polymaker is polycarbonate and polybutylene terephthalate (PC+PBT) alloy. Designed for fused deposition modeling (FDM) and 3D printing filament fabrication (FFF). Exhibits good strength, toughness and ductility at low temperature. It is created using Covestro’s Makroblend® family. Provides good printing quality, good chemical- and low temperature impact resistance. Polymaker™ PC-PBT performs very well under extreme circumstances whether in contact with hydrocarbon based chemicals and operating at subzero temperatures.
