Polyurethan Ejector springs

In tool and fixture construction, ejector springs made of polyurethane are used, which have to meet a wide variety of requirements. A rough distinction is made between a resilient (energy-conserving) or a damping (energy-absorbing) function.

The essential parameters for the successful use of polyurethane are:

• Mechanical properties (spring characteristics, tendency to settle, compression set, rebound resilience, hysteresis …)
• Chemical resistance to hydrolysis, solvents, fats, …

Since we develop the polyurethane formulations used ourselves, we can respond precisely to your requirements.
