Styrene-Butadiene-Styrene for flexible applications and high adhesion
<p><strong>SBS</strong> is a <strong>block thermoplastic elastomer belonging</strong> to the styrenic family.<br />
It is characterized by a flexible and workable structure that makes it ideal for applications requiring softness, elasticity, and chemical adhesion to various substrates.<br />
Commonly used in co-molding, grips, footwear, soft-touch items, and flexible packaging, thanks to its <strong>ease of coloring</strong>, <strong>recyclability,</strong> and good <strong>mechanical resistance</strong>.<br />IonPlast offers SBS in various grades, also <strong>suitable for food contact</strong>, with customizable hardness and properties based on the intended use. </p>
