What are the advantages of polyurethanes over traditional rubbers?

Polyurethanes (PU) offer several advantages over traditional rubbers. 

Here are some of the main advantages of polyurethanes:

Wear resistance: Polyurethanes are known for their high resistance to wear and abrasion. They are able to withstand friction and constant wear on rough or bumpy surfaces, maintaining their integrity and performance for a longer period than traditional rubbers.

Flexibility and resilience: Polyurethanes offer a good combination of flexibility and resilience. They can deform and return to their original shape without suffering permanent damage. This property makes them suitable for applications requiring impact resistance, energy absorption and shock-absorbing capacity.

Customisable hardness range and properties: Polyurethanes are available in a wide range of hardnesses, ranging from soft and elastic to hard and rigid. This allows the selection of the most suitable type of polyurethane for the specific needs of the application. In addition, the properties of polyurethanes can be customised through chemical formulation to achieve desired characteristics such as chemical resistance, oil resistance, stiffness and more.

High resistance to mechanical stress: Polyurethanes exhibit excellent resistance to mechanical stresses such as tensile, compressive and flexural. They can withstand heavy loads without permanent deformation or structural failure.

Versatile applications: Polyurethanes find application in a wide range of sectors and industries. They are used in automotive components, sports equipment, footwear, building materials, industrial equipment, thermal and acoustic insulation, and much more. Their versatility allows tailor-made solutions to be developed for the specific needs of each application.

Longer life: Thanks to their wear-resistant, flexible and resilient properties, polyurethanes tend to be more durable than traditional rubbers. This means they require less maintenance and less frequent replacement, leading to a lower total cost of ownership over time.

It is important to note that the specific benefits of polyurethanes may vary depending on chemical formulation, production process and specific applications. 

Therefore, it is advisable to consult polyurethane manufacturers or experts in the field to obtain specific information on the characteristics and benefits of polyurethanes for the desired application.
