What is Polymaker PolyFlex TPU90?

Polymaker PolyFlex TPU90 is a high-performance TPU filament designed to offer exceptional flexibility and toughness. With a density of 1.12 g/cm³, it provides a balanced combination of lightweight characteristics and structural integrity. This filament is an excellent choice for producing parts that require elasticity, impact resistance, and durability.

Key Properties of Polymaker PolyFlex TPU90

1. Tensile Strength

One of the standout features of PolyFlex TPU90 is its tensile strength, which measures at 30.0 ± 0.66 MPa. This property indicates the material’s ability to withstand significant pulling forces without breaking, making it suitable for applications where mechanical strength is paramount.

2. Elongation at Break

PolyFlex TPU90 exhibits remarkable elongation at break, with values ranging from 528 to 586.8 ± 15.3%. This high elongation rate means that the material can stretch considerably before breaking, which is ideal for flexible and resilient parts.

3. Shore Hardness

With a Shore hardness rating of 90A, PolyFlex TPU90 strikes a balance between flexibility and rigidity. This hardness level ensures that the material is soft enough to bend and flex under pressure, yet firm enough to maintain its shape and provide structural support.

Optimal Printing Settings for PolyFlex TPU90

To achieve the best results with Polymaker PolyFlex TPU90, it is crucial to use the correct printing settings. Here are the recommended parameters:

1. Nozzle Temperature

The optimal nozzle temperature for printing PolyFlex TPU90 ranges between 210°C and 230°C. Maintaining this temperature range ensures proper extrusion and adhesion between layers, resulting in smooth and consistent prints.

2. Build Plate Temperature

A build plate temperature of 25°C to 60°C is recommended for PolyFlex TPU90. Using a heated bed helps to prevent warping and improves adhesion to the build surface, ensuring that your prints stay in place during the printing process.

Applications of Polymaker PolyFlex TPU90

Polymaker PolyFlex TPU90 is versatile and can be used in various applications across different industries. Here are some common uses:

1. Flexible Parts and Prototypes

Thanks to its high elongation at break and Shore hardness of 90A, PolyFlex TPU90 is ideal for producing flexible parts and prototypes. This includes components like gaskets, seals, and custom-fit enclosures that require both flexibility and durability.

2. Wearables and Fashion Accessories

The material's softness and flexibility make it suitable for wearables and fashion accessories. From wristbands to custom-fit shoes, PolyFlex TPU90 allows designers to create comfortable and durable products that conform to the wearer's body.

3. Robotics and Automation

In the field of robotics and automation, PolyFlex TPU90 is used to produce flexible joints, grips, and bumpers. Its ability to withstand repetitive movements and impacts makes it an excellent choice for parts that require both flexibility and resilience.

4. Medical Devices

PolyFlex TPU90’s biocompatibility and flexibility make it suitable for various medical applications, such as prosthetics, orthotics, and custom medical devices. The material's ability to conform to complex shapes and provide comfortable support is particularly beneficial in the medical field.
