eSUN eFlex TPU-85A is a soft, highly elastic thermoplastic polyurethane (TPU) filament engineered for 3D printing applications that demand flexibility, impact resistance, and durability. At 85A on the Shore hardness scale, this is the softer, more pliable grade in eSUN's eFlex TPU lineup (which also includes a firmer 87A option) — making it especially well suited to cushioning parts, dampeners, protective covers, gaskets, and other applications where extra give and rebound are needed.

Key Features

• Soft, rubber-like flexibility with strong elongation before breaking
• High resistance to tearing, abrasion, and repeated impacts
• Cold-resistant and chemical/solvent-resistant
• Smooth surface finish for clean, consistent prints
• Reliable layer adhesion and dimensional stability during printing
• Clear/natural colorway for a translucent finish
