“ELTEK was an absolute delight to work with! A true resource when it comes to extended time testing of material failure, and explains concepts clearly, succinctly, and relevantly. All requests for supplemental information, including the return of aged samples, were handled cheerfully and in a timely manner. These particular samples were very challenging because of the fact that decomposition temperatures are likely in excess of the polymer melting temperatures, but ELTEK worked diligently with us to find ways to both age and test the materials and thereby meet our information needs. I would ABSOLUTELY work with ELTEK again, and will recommend the lab to my colleagues.”
