A urethane spring is a flexible component made of urethane, often used for its resilient properties. Typically crafted from molded urethane, these springs provide excellent shock absorption and cushioning, enhancing comfort and reducing the impact of vibration and shocks. Urethane's lightweight nature also contributes to weight reduction in products, which is especially beneficial in transportation equipment such as vehicles and aircraft.
However, urethane is sensitive to high temperatures and may deteriorate under prolonged exposure. Special attention should be paid to high-temperature environments, like vehicle engine compartments. It's also crucial to select the right hardness and thickness of urethane to avoid deformation under heavy loads.
Urethane springs have a wide range of applications, thanks to their cushioning and shock-absorbing properties. Key uses include:
These springs are used in automobile seats to provide comfort and reduce fatigue during long drives.
Urethane springs are popular in furniture such as sofas and chairs for their comfort and durability and in mattresses and beds for body-conforming support and pressure dispersion.
They are used in buildings to enhance earthquake resistance and stability by absorbing vibrations from external sources like earthquakes and wind.
Urethane springs work based on the elastic properties of urethane. When external force is applied, urethane deforms and then returns to its original shape once the force is removed. This elasticity, coupled with vibration absorption properties, makes urethane springs effective for cushioning and shock absorption in various applications.
When choosing a urethane spring, consider factors such as load, hardness, size, shape, comfort, and durability. The right selection depends on the specific application, whether it's for comfort in furniture or durability in automobile suspensions.
