what is TPU

Thermoplastic polyurethane (TPU) is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. Further, it can be processed on extrusion as well as injection, blow and compression molding equipment. It can be vacuum-formed or solution-coated and is well suited for a wide variety of fabrication methodologies. TPU can even be colored through a number of processes. But more so than any other thermoplastic elastomer, TPU can provide a considerable number of physical property combinations making it an extremely flexible material adaptable to dozens of uses.

This is partly because TPU is a linear segmented block copolymer composed of hard and soft segments. The hard segment can be either aromatic or aliphatic. Aromatic TPU's are based on isocyanates such as MDI while aliphatic TPU’s are based on isocyanates like H12 MDI. When these isocyanates are combined with short-chain diols, they become the hard block. Normally it is aromatic, but when color and clarity retention in sunlight exposure is a priority, an aliphatic hard segment is often used.
