Thermoplastic Polyurethane (TPU) Injection Molding
When you look at the characteristics of thermoplastic polyurethane it is not difficult to see why it is so popular for injection moulding products. The main advantages of using thermoplastic polyurethane includes:
- Abrasion resistant
- Impact strength
- Elasticity similar to rubber
- Protection against oil, grease and other similar fluids
Unfortunately, we don’t really have enough space to list all of the ways in which thermoplastic polyurethane can be used. However, it is the flexibility, while able to maintain an overall rigidity, which makes it so useful. It is used with injection moulding products such as:
- Sports footwear soles
- Car bumpers
- Mobile phone protective coverings
- Computer components
- Floatation devices
- Protective goggles
When you think of sports footwear, such as football boots, where the sole requires a degree of rigidity and flexibility, thermoplastic polyurethane is just perfect.

Understanding Thermoplastic Polyurethane (TPU) Injection Molding Materials
Thermoplastic polyurethane (TPU) injection molding materials are a popular choice for creating a wide range of products, including automotive parts, sports equipment, and medical devices. TPU is a type of thermoplastic elastomer that combines the properties of both plastic and rubber, making it an ideal material for injection molding.
TPU is a versatile material that can be molded into a variety of shapes and sizes, making it an excellent choice for manufacturers who need to produce complex parts. Additionally, TPU injection molding materials are known for their durability, flexibility, and resistance to abrasion, chemicals, and UV radiation.
One of the main advantages of TPU injection molding materials is their ability to be processed at lower temperatures than other thermoplastics, such as nylon or polycarbonate. This lower processing temperature means that TPU materials are less likely to shrink or warp during the molding process, resulting in more precise and consistent parts.
Another advantage of TPU injection molding materials is their ability to be easily colored or tinted, allowing for customization and branding opportunities. Additionally, TPU materials can be easily molded over-molded onto other materials, such as metal or plastic, providing added functionality and design options.
When selecting TPU injection molding materials, it's important to consider factors such as the intended application, the specific properties required for the part, and the processing parameters. Different grades of TPU are available with varying properties, such as hardness, flexibility, and chemical resistance, allowing manufacturers to select the most suitable material for their needs.
In conclusion, TPU injection molding materials are an excellent choice for creating durable and flexible parts with complex geometries. With their unique properties and versatility, TPU materials offer many advantages for manufacturers in a variety of industries.
