Can you melt TPEs? If we’re being nuanced, thermoplastic elastomers don’t technically melt. Once heated, TPEs get softer and turn into a form that allows the material to flow freely, but they don’t turn into a liquid state as is the case when something is melted.

What is the difference between TPV and TPE?

TPV, short for thermoplastic vulcanizate, offers a type of material that fits into the thermoplastic elastomer (TPE) family. TPV and TPE differ from each other because of the way the rubber component enters the equation for the compound.
