TPU - Flex Black filament by Kingroon, or Thermoplastic Polyurethane, is a flexible and durable 3D printing filament that produces parts with a rubber-like texture. TPU is ideal for printing objects that require flexibility, impact resistance, and good adhesion, such as phone cases, gaskets, and sneaker soles. 
The hardness of Kingroon TPU filament is 95A, the tensile strength is high, and the long-term compression deformation rate is low. lt can be used without a specialized soft extruder.
