Urethane Durometer Chart

One of the more commonly asked questions we get is about urethane durometer. Durometer is the measure of resistance to surface penetration. This is measured with an actual durometer hardness tester that pushes against the urethane and is represented in the shore A, D scales. A being the softer side of things and D being on the harder side.

The measurement of urethane durometer is the same regardless of manufacturer but the way urethane is manufactured can vary greatly. Acrotech Inc. which has been producing K•Prene® Urethane for the last 30 plus years has been at the forefront of custom molded urethane and urethane based products. Our history and success has consistently produced durable yet resilient urethane while maintaining exceptional value. We are certain that over time by correctly using K•Prene® you will see significant cost savings and value.

For those that do not deal with urethane on a daily basis and or are looking to potentially produce parts with urethane please use the following chart. This chart is used as a guideline only comparing everyday items to the shore A / D durometers of our standard K•Prene® products.

Of course there will be questions. We are here to answer them. In certain cases and applications you may benefit from a different durometer than what you are currently using. We can discuss this more in detail if you contact us. If you are just starting and would like to look over our catalog please visit this page to request your own along with a sample keychain. If you have a CAD file or would like to upload a sketch of a product that you’d like to make in urethane please visit this page for more information on how to do that.
