4. Applications

As TPUs cost more per kilogram than PVC and other low-performance plastics, they are generally chosen for delicate applications where failure is ruled out. Such applications require exceptional performance and/or a combination of properties that other materials lack (flexibility at low temperatures, high fatigue resistance, softness and long-lasting resistance to skin grease, etc.). Although TPU materials are generally more expensive, their strength and toughness mean that they can be used in thinner thicknesses, thus reducing the cost of the materials.

• Sterilization

Polyether and polyester TPUs can be sterilized by dry heat with ethylene oxide, without yellowing, and by gamma rays in cases where slight yellowing is acceptable. If carried...
