Technical specifications
Liqcreate Flame Retardant HDT is a rigid off-white photopolymer 3D-printing resin and can be processed on most open resin based 3D-printers. 3D-printed parts from this material can withstand high temperatures (HDT-B upto 257°C / 495°F) without posing a fire hazard due to its self-extinguishing capabilities. The material is perfect for creating parts that need comply with UL94 V0 test standards, such as parts for car interior, railway, airplane and electronics. In addition, it can be excellent for tooling manufacturing aids, connector housings and covers.
