Advantages of TPU


TPU is a flexible material. You can stretch them and their shape or size will remain the same. However, there are TPU materials that are hard. It varies on their grade.


Thermoplastic polyurethane products are highly durable and have high impact strength. They can withstand tear and wear.

Weather Resistance

Injection-molded TPU products won’t rot under outdoor applications since they are resistant to water, ozone, and UV light.

Chemical Resistance

TPU is resistant to various chemicals and solvents.

Low-Temperature Resistance

Injection-molded TPU products can be used in low-temperature applications. Their flexibility and strength will retain even under low temperatures.


The TPU products can be used in wet or moist applications since they don’t absorb water.

Abrasion Resistance

Since they are abrasion-resistant, you can use them in environments where friction is present.


Other TPU grades have biocompatibility. Those grades can be used in dental or medical applications

Electrical Insulation

TPU features electrical insulation. Due to that, it can be used in producing parts used in electronics or electrical applications.

Variety of Applications

TPU injection molding can produce TPU products such as:

  • Gaskets
  • Gears
  • Footwear
  • Hose
  • Tubing
  • Phone cases
  • Grips
  • Caps
  • Prosthetics and orthotics
  • Sporting goods

It can also produce injection-molded TPU products used in medical, automotive, electronics, electrical, and many other industries.

Processes of TPU Injection Molding

Preparation of Material

This process starts by drying the TPU pellets to remove their moisture.

Feeding of Material

The TPU pellets will be fed to the hopper. Then, they will be melted into the barrel.


The melted TPU will be injected into the mold cavity at high pressure.


Then, the TPU molds will solidify by cooling them.


When it’s cooled, the molded TPU products will be removed from the mold cavity. The products will be then inspected to see if there are defects.


The injection-molded TPU products may need assembly, printing, painting, and other post-processes you require.
