TPU, or Thermoplastic Polyurethane, is a highly versatile thermoplastic material that finds applications in various fields, from manufacturing to everyday life. With its excellent load-bearing capacity, abrasion resistance, and high elasticity, TPU is becoming the top choice for many products. Let's explore the outstanding advantages and diverse applications of this type of plastic, as well as the reasons for its increasing popularity in the following article.
1. Overview of TPU Plastic
TPU, known as Thermoplastic Polyurethane, is a distinguished thermoplastic known for its flexibility and high usability. Invented in 1959 by BF Goodrich, TPU has now become one of the most advanced materials across multiple industries.
Physical Properties: TPU stands out with its excellent temperature resistance, operating effectively within a range from -40°C to 120°C. Specifically, TPU exhibits elastic properties ranging from 300% to 600%, allowing it to perform well in applications that require high flexibility and elasticity. The surface of TPU is also highly resistant to oils, water, and chemicals, keeping products clean and extending their service life. Furthermore, with a density ranging from 1.10 to 1.25 g/cm³, TPU is suitable for various sectors, from sporting goods production to healthcare technology.
Chemical Properties: TPU is formed from the reaction of diisocyanates with polyols, resulting in a stable and durable polymer structure. Boasting excellent oxidation resistance, TPU products are less prone to yellowing or deterioration from environmental exposure. Additionally, TPU is free from harmful components such as BPA or phthalates, making it a safe choice for producing items that come into direct contact with humans, especially in the healthcare field.
1.1 Technical Specifications
- Hardness: TPU hardness ranges from Shore A 60 to Shore D 80, allowing customization of flexibility and durability according to product requirements.
- Tensile Strength: TPU achieves tensile strength of approximately 30-65 MPa, enabling excellent resistance to deformation and protecting products effectively.
- Elastic Modulus: Ranges from 10 to 1000 MPa, ensuring flexibility for many different applications.
1.2 Advantages and Disadvantages
Advantages:
- Superior abrasion and impact resistance, making it suitable for sports and consumer goods applications.
- Flexibility in design and manufacturing, easily bendable without losing shape.
- High durability and excellent heat resistance, increasing product lifespan.
Disadvantages:
