Thermoplastic Polyurethane (TPU) is a type of polymer resin that is known for its flexibility, durability, and versatility. It is a thermoplastic material, which means it can be melted and reprocessed multiple times without losing its original properties.
TPU is commonly used in various industries, including automotive, electronics, footwear, and sportswear. It is often used to make products such as phone cases, cables, hoses, seals, gaskets, and inflatable structures.
Some key properties of TPU include:
1. Flexibility: TPU has excellent flexibility, allowing it to bend and stretch without breaking. This makes it suitable for applications where flexibility is required, such as in shoe soles or flexible electronic components.
2. Abrasion resistance: TPU has good resistance to abrasion, making it suitable for applications that require durability and resistance to wear and tear.
3. Chemical resistance: TPU is resistant to many chemicals, including oils, solvents, and greases. This makes it suitable for applications where exposure to chemicals is expected.
4. Weather resistance: TPU has good weather resistance, meaning it can withstand exposure to sunlight, moisture, and extreme temperatures without degrading or losing its properties.
5. Adhesion: TPU has good adhesion to various substrates, allowing it to be easily bonded or laminated with other materials.
Overall, TPU is a versatile material that offers a balance of flexibility, durability, and chemical resistance, making it suitable for a wide range of applications.
