**ARDL Notice
ARDL is working hard to maintain supply of our certified materials & test plaques. Unfortunately, with the current logistic delays due to issues with shipping and the ongoing pandemic, ARDL may not be able to fulfill all orders at this time. In some cases, material ingredients required for compounds are delayed or not available currently and there is not a set date when they will become available. We are also experiencing situations where materials have been discontinued completely. We appreciate your understanding and apologize for these issues causing unknown lead times. For the latest updates and any questions or concerns about an order, please reach out to our Compounding/Mixing department at answers@ardl.com. We value your choosing ARDL for your slab and compound materials and hope these issues will be resolved soon.
Members of the oil and grease industry need control reference rubber compounds to evaluate the effects of changes in oil or grease composition or additive packages on rubber. ARDL is the approved source for these vital control compounds. The plaques (6″ x 6″ x 0.080″ cured rubber sheets) are produced by ARDL under carefully controlled and monitored conditions.
All materials & test plaques are certified to AMS, SAE, ISO and Mercon ATRR specifications. ARDL is a member of the National Lubrication Grease Institute.
