OnFlex™ Thermoplastic Elastomers Solutions for Automotive Applications To keep up with industry demands, regulatory challenges and end-user preferences, it’s imperative to consider the influence of material specifications at the beginning of the product development cycle. Known for offering tight seals and reducing vibration and noise, certain thermoplastic elastomers (TPEs), like OnFlex™ grades, may be better suited for your particular application than the historically incumbent materials, like general purpose TPEs, thermoplastic vulcanizates (TPV), and thermoplastic polyolefins (TPO).
