How did we earn an industry reputation as a materials expert? Customers recognize the difference in our products. We work directly with our material suppliers – in the lab or right beside the press as it turns out a new product – to develop resins specifically formulated for each application. Specialized materials can fill a mold cavity better … produce superior tensile strength … push environmental tolerances further. It’s one reason HellermannTyton will never be just another parts maker.
