TPU (Thermoplastic Polyurethane)

TPU (Thermoplastic Polyurethane)

First developed in 1937, TPU is one of the groundbreaking developments in materials science. When heated, it becomes soft and easily processable, while cooling it causes it to harden and maintain its structural integrity. These properties make TPU reusable and shapeable in production processes, making it an eco-friendly and economical choice.

Thermoplastic Polyurethane (TPU) stands out with its unique characteristics, providing flexible solutions to the rapidly changing manufacturing needs of the modern world. Combining both soft and rigid segments, TPU offers the flexibility of rubber and the rigidity of plastic. This unique combination makes TPU a preferred material across a wide range of applications. Whether it is shoe soles, industrial hoses, or delicate electronic components, TPU provides an excellent solution to every challenge.

TPU is a polyurethane thermoplastic elastomer known for its high abrasion resistance, flexibility, and ease of processing. This material, containing both soft and rigid segments, can be as flexible as rubber and as hard as plastic.

The soft segments of TPU perform excellently at low temperatures, providing resistance to weather conditions and solvents. The rigid segments enhance mechanical strength and phase separation. This formulation allows TPU to be used in various products with different hardness, density, and elasticity characteristics.

Soft type TPUs (65–85 Shore A) have lower tensile strength, while hard type TPUs (50–70 Shore D) exhibit high tensile strength. One of the most notable features of TPU is its high abrasion resistance, wide temperature range elasticity, and exceptional resistance to oils.

Used in a variety of fields, from shoe soles to wire and cable coatings, hoses and tubes to films and sheets, TPU provides excellent performance for any application requiring flexibility and durability. Even in adhesives and specially molded parts, TPU’s superior properties make a significant difference. In shoe soles, TPU offers both comfort and durability, while in wire and cable coatings, it provides high insulation and protection. In hoses and tubes, this material offers flexibility and longevity, and in films and sheets, it provides both aesthetic and functional solutions. Even in sensitive applications such as adhesives and specially molded parts, TPU’s superior properties simplify your work and enhance product quality. Whether in everyday life or industrial applications, the superior performance and reliability provided by TPU perfectly adapt to the dynamics of the modern world.
