TPU, a high-performance polymer, has emerged in the medical industry in recent years.Its unique physical and chemical properties make it play an increasingly important role in the medical field.TPU (thermoplastic polyurethane elastomer) is a high-performance polymer with high strength, high toughness, wear resistance, oil resistance and other characteristics, making it an important position in the medical industry.Its ease of processability, good resilience and low temperature performance have broadened the scope of application.Thermoplastic polyurethane elastomer (TPU) is a unique elastomer with excellent overall properties such as high strength, high toughness, wear resistance, and oil resistance.It is not only easy to process, but also can be plasticized when heated and dissolved in solvents, making it widely used.In addition, TPU also has good resilience and low temperature performance, which further broadens its application field.TPU can be classified according to different classification criteria.For example, according to the soft segment structure, TPU can be divided into polyester type, polyether type and butadiene type, which contain different functional groups.Similarly, according to the hard segment structure, TPU can be divided into aminoester type and aminoester urea type.In practical applications, polyester type and polyether type TPU are the most common.Polyether TPU is known for its high strength, hydrolysis resistance and high resilience, while polyester TPU exhibits excellent tensile properties, flexural properties and friction resistance.
Classification of TPU in the medical field
Like other types of polyurethane, TPU also has the characteristics of high modulus, high strength, high elongation and high elasticity.At the same time, it also exhibits excellent wear resistance, oil resistance, low temperature resistance and aging resistance.In particular, its high tensile strength, large elongation and low permanent deformation rate of long-term compression make TPU have a wide range of application prospects in the medical field.Medical TPU is classified according to different characteristics and uses, such as for catheters, adhesives, artificial joints, etc.Common types include aliphatic polyetheramines, aromatic polyurethane, etc., All kinds of TPU show different biocompatibility and physical properties.
