Your Guide to TPE’s

As more OEM’s focus on product innovation surrounding ergonomics and aesthetics, we have seen increased demand for TPE usage in plastic parts and assemblies. So, what is a TPE? The answer can be complex depending on the intended use, environment, and performance expectations.

TPEs are soft and flexible like elastomers/rubber but can be processed with conventional fabrication techniques (injection molding, extrusion, etc.) and reprocessed like a thermoplastic. Simply put, there are many types of elastomers that fall under the TPE umbrella, and choosing the right one for an application can be a tricky process. Temperature and chemical resistance, overmold bonding, hardness, and tactile feel are just some of the qualifying factors to review when selecting the best TPE for a new or existing application.

Almost all TPEs contain two or more distinct polymeric phases: hard and soft. Their properties depend on the chemistry phases being finely and intimately mixed. Below are some common examples of TPE chemistries:
