Urethane Durometer Chart
Below you will find our urethane durometer chart that points out our 6 main durometers. This is intended on giving you a better understanding of how urethane durometer can relate in comparison to common everyday items. This chart is to be understood as a general guide and is in no way to represent the total accuracy of urethane durometers. Durometers can vary +- depending on the mix and pour, however Acrotech will always inspect items prior to final shipment for the highest quality and grade urethane that you can purchase.
The K•Prene® grades listed below are the materials most often used for metal forming. The type of application, available press tonnage, and characteristics of the metal to be formed will assist in selecting the best grade and size. In addition, the urethane provides a unique combination of properties.
These include: high load-bearing capacity; toughness; hardness; abrasion resistance; and oil and ozone resistance. To the right you will see a handy comparison chart that will give you a very good idea where urethane durometer falls into normal everyday items. Use this a a guide when choosing the appropriate level of hardness for your project. Also below our standard durometers are further explained for application use and its primary qualities. Of course the uses are endless but you will find a lot of uses for urethane in Industrial, Woodworking and Automotive applications.
K-400A Yellow 40A Durometer
A low durometer material with a high coefficient of friction that will satisfy countless industrial needs such as rollers, bumpers, etc.
K-600A Black 60A Durometer
High coefficient of friction and excellent tensile strength makes this material a good choice for feed rolls and many other industrial applications.
K-800A Orange 80A Durometer
Good tear strength, abrasion resistance and excellent flex life. Good low temperature properties. Requires lower tonnage. Withstands greater deflection. Maximum recommended deflection 35%.
K-900A Blue 90A Durometer
Withstands consistent flexing. Good cut resistance. Good load-bearing capacity. Maximum recommended deflection 25%.
K-950A Red 95A Durometer
High tensile strength for higher blank-holding pressure. High load-bearing capacity. Best tear strength. Best cut resistance. Best abrasion/wear resistance. Maximum recommended deflection 15%.
K-750D Brown 75D Durometer
Great load-bearing capacity. Excellent machinability and abrasion resistance. Offers great rigidity, yet will deflect. Maximum recommended deflection 5%.
