Polyurethanes offer numerous advantages over other materials, which contributes to their widespread use in various industries. Here are some of the main advantages of polyurethanes over other materials:
Versatility: Polyurethanes are extremely versatile and can be formulated to achieve a wide range of properties. They can be rigid or flexible, elastic or hard, open-cell or closed-cell, depending on the needs of the application. This versatility allows polyurethanes to adapt to many different industries and applications.
Mechanical resistance: Polyurethanes offer excellent mechanical properties, such as resistance to wear, traction, bending and compression. They are able to withstand high loads and deformations without suffering significant damage. This mechanical strength makes them suitable for applications requiring robust and durable components.
Elasticity and resilience: elastomeric polyurethanes can deform under load and resume their original shape once the load is removed. This elasticity and resilience property makes them ideal for applications where good shock absorption and resistance to dynamic stress is required, such as shoe soles, seals and shock absorbers.
Wide hardness range: Polyurethanes can be formulated to a wide range of hardnesses, from soft to hard. This allows polyurethanes to be adapted to the specific needs of the application, providing a wide choice of materials with different mechanical properties.
Chemical resistance: Polyurethanes can be formulated to resist a wide range of chemicals, such as oils, solvents, acids and bases. This chemical resistance makes them suitable for applications in chemically aggressive environments, such as in the chemical and oil & gas industries.
Good insulation properties: Polyurethanes can offer excellent insulation properties, both thermal and acoustic. They are used in thermal insulation for buildings, refrigerators, household appliances and piping. They can also act as acoustic insulators in applications such as sound-absorbing foams and sound-insulating panels.
Ease of processing: Polyurethanes can be processed by various production techniques, such as casting, spraying, extrusion and injection. This ease of processing allows the production of components with complex and detailed shapes, adapting to design requirements.
Lightness: Polyurethanes can be made with relatively low densities, which makes them lightweight compared to other materials with similar properties. This is advantageous for applications requiring lightweight components, such as in the automotive or aerospace industries.
Abrasion resistance: Polyurethanes are known for their abrasion resistance, which means they can withstand wear caused by friction and friction. This property makes them suitable for applications that require components to withstand wear and tear, such as cable sheaths and conveyor rolls.
