BigRep TPU 98A
BigRep TPU 98A Flexible Engineering Filament
BigRep TPU 98A is a high-performance thermoplastic polyurethane filament engineered for industrial applications requiring flexibility, durability, and exceptional wear resistance. With a Shore hardness of 98A, it offers the ideal balance between elasticity and strength, making it suitable for parts that must withstand repeated impact, bending, and abrasion.
Combining excellent chemical resistance with outstanding tear strength and high elongation, BigRep TPU 98A is ideal for functional components exposed to demanding mechanical environments. Its flexibility and resilience make it well suited for seals, gaskets, protective covers, vibration-dampening components, and other end-use parts where traditional rigid plastics are not suitable.
Optimized for industrial FDM/FFF printing, BigRep TPU 98A delivers consistent extrusion, excellent layer adhesion, and reliable performance on large-format and standard open-material 3D printers.
