PolyMaker™ PC-PBT

Technical Datasheet | Supplied by Polymaker
PolyMaker™ PC-PBT by Polymaker is a blend of polycarbonate (PC) and polybutylene terephthalate (PBT) designed specifically for fused deposition modeling (FDM)/ fused filament fabrication (FFF) 3D printing. Exhibits good strength, toughness and natural ductile fracture behavior at low temperature. It is created using Covestro’s Makroblend® family. Offers good chemical resistance, low temperature impact and superior printing quality. Polymaker™ PC-PBT performs very well under extreme circumstances whether in contact with hydrocarbon based chemicals or operating at subzero temperatures.
