TPU and PU are very important polymers that have a wide range of applications in different industries. TPU stands for thermoplastic polyurethanes while PU stands for polyurethanes. TPU is a type of thermoplastic elastomer. It has many improved properties than other thermoplastic elastomers. PU is a polymer that is different from other polymer materials based on its nomenclature; this polymer is named based on the urethane linkages present in the polymer. There are many differences between these two types. The main difference between TPU and PU is that TPU has no cross-links whereas PU can have cross-links based on the type of polyols used.<\/strong><\/p>\n\n\n\n\n\n\n\n\n\n

What is TPU<\/h2>\n

TPU stands for thermoplastic polyurethane<\/strong>. It is a type of thermoplastic elastomer. Hence, it is elastic and melt-processable. It has many favorable properties such as elasticity, transparency, resistance towards oils and abrasion resistance. TPU is a form of block copolymer (contains soft and hard segments).<\/p>\n

TPU can be colored through a number of processes, and it is also extremely flexible. This is mainly due to the composition of hard and soft segments. The hard parts are either aromatic or aliphatic. They are generally aromatic, but the aliphatic hard segments are preferable when the color and clarity retention in exposure to sunlight is more important.<\/p>\n

in oil resistance. Some applications of TPU are given below.<\/p>\n
