FDM TPU 92A
Production-grade Elastomer
FDM® TPU 92A is a thermoplastic polyurethane with a Shore A value of 92. The material exhibits high elongation, superior toughness, durability and abrasion resistance.
FDM TPU 92A brings the benefits of elastomers to FDM 3D printing and offers the capability to quickly produce large and complex elastomer parts. Typical applications include flexible hoses, tubes, air ducts, seals, protective covers and vibration dampeners. FDM TPU 92A is available on the F123™ Series 3D Printers and is compatible with QSR™ soluble support material.
