Flexible Polyurethane (FPU)
A firm material that has “give”
Offering high impact strength and cycle life, the FPU family consists of materials without equal in the additive industry. These materials are designed to withstand repetitive stresses, making them ideal for tough enclosures, hinging mechanisms, and friction fits. The FPU family is comparable to polypropylene.
Sample Uses:
Living Hinges
Clips & Fasteners
Strain Relief Parts
