Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer that can be plasticized by heating and dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance, and good processing performance. It is widely used in footwear, medical, food, consumer electronics, packaging, industrial supplies, automotive, military products, textiles and other industries.

Taurine was first separated from taurine, also known as β- Taurine, taurocholine and bovine bilirubin are non protein amino acids containing sulfur, which exist in free state in the body and do not participate in the biosynthesis of protein in the body.
