| Technical Information | Compression-Deflection Characteristics |

Polyurethanes under the Plei-Tech® name are based upon PPDI, NDI, and TDI and are typically used in shock absorbing applications or vibration absorbers. Depending upon your requirements, our polyurethanes can be varied in durometer, configuration and chemical make-up to offer the best shock absorption performance.

As a general rule, compression elements should not be compressed more than 25% of the original height. As the frequency of compression increases, the percentage of compression should decrease in order to maximize bumper life.
