Listed below are definitions and additional information on the terms and identification numbers found on the product data sheet. |

Shore A Hardness |
|
 |
| |
This test involves the penetration of a specific shaped point when forced onto the elastomer surface. "Shore A" specifies the type of durometer. This test permits hardness measurements based on initial indentation and/or indentation after a specified time period. The reported value of 95 Shore A is for an initial reading. |

Tensile Strength |
|
 |
| |
The reported tensile strength is the force required to stretch the elastomer in one direction. The reported value is 1750 psi at break. In other words, 1,750 pounds could be suspended from a one-inch-square rod before failure. |
|
 |
| |
Elongation |
|
 |
| |
This is the distance the material can stretch before failure. 100% elongation implies that a sample can be stretched to twice its original length before breaking. 200% elongation means the sample can be stretched to three times its original length before failure occurs. The higher the elongation, the more elastic the material. |
