Stereon™

Stereon™ is a styrene-butadiene multiblock copolymer which is sometimes referred to as a thermoplastic elastomer. Stereon™ (SBS) multiblock and thermoplastic elastomers blend easily with polystyrene to give alloy products improved impact resistance and toughness.

Their free-flowing form allows convenient handling in conventional plastics blending systems. Stereon™ can be added in small amounts to extrusion or molding grade HIPS and general purpose polystyrene to enhance and customize properties such as:

Stereon™ is also beneficial in restoring the properties of flame retardant HIPS and recycled and post-consumer polystyrene to useful levels.

Stereon™ thermoplastic elastomers offer a wide range of properties and are the TPE of choice for specialty applications and engineering resins.
