Because the material has never been combined or processed in this precise way, the “recipe” becomes a trade secret that the manufacturer saves for future use cases. To help you identify the right materials for your product, they will need to know: 1. the kind of environment in which your product will be used 2. what kind of properties you need (e.g., stretchy, hard or soft, color) Is TPE the best material for my products? At Avient, we use a collaborative approach to deliver the specialty polymer formulations, services and sustainable material solutions specific to your application and property needs.
