TPE-S: is it rubber or is it plastic?

A styrenic thermoplastic elastomer, or TPE-S, is a material intermediate between rubber and plastic—it has characteristics of both. Let’s look at them in detail: 🔹 Structure It is composed of styrene blocks (rigid) and elastomeric blocks (rubbery), typically butadiene or isoprene (e.g., SBS, SEBS). 🔹 Behavior • At room temperature → it behaves like rubber […]
