There are a variety of TPE technologies available offering a wide range of mechanical properties and end-use performance. In may cases, the performance range of different TPE polymers overlap and make specific grade selection uncertain.

Knowing how a material will be used in its end-use application is imperative during the material selection process. RTP Company product development engineers are well versed in seeking out the information necessary to ensure an appropriate material is recommended. This TPE application checklist has been developed to help you prepare thoughtful answers to common questions.
