Thermoplastic Polyurethane
- Snippet from Wikipedia: Thermoplastic polyurethane
Thermoplastic polyurethane (TPU) is any of the polyurethane polymers that are thermoplastic; that is, they become pliable when heated and harden when cooled. This is in contrast to most polyurethanes, which are thermosets, hardening irreversibly. Thermoplastic polyurethanes (TPUs) reveal vast combinations of both physical properties and processing applications. Usually, they are flexible and elastic with good resistance to impact, abrasion and weather. With TPUs, there is the possibility for colouring as well as fabrication using a wide range of techniques. The incorporation of TPUs could therefore improve the overall durability of many products.
Thermoplastic polyurethanes have many desirable properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers, consisting of linear segmented block copolymers composed of hard and soft segments.

A versatile type of plastic known as TPU combines the flexibility of rubber with the reusability of thermoplastics. These remarkable materials are known for their transparency, resistance to wear and tear from oil and grease, and overall toughness. From a technical point of view, TPUs are thermoplastic elastomers composed of alternating hard and soft segments linked together in a chain-like structure.

- High wear resistance
- Low temperature performance
- High shear strength
- High flexibility
- Transparency
- Oil and grease resistance
Commercially available TPUs can be divided into two sub-categories.
- Based on polyester derived from adipic acid esters.
- Polyethylene-based polyethylene derived from tetrahydrofuran ethers.
