Custom Profiles tri-extrusion technology allows for combining three compatible polymers together through a common profile co-extrusion die. The benefit of tri-extrusion is the ability to provide different finishes, colors, and combinations of rigid and soft materials. For example, a tri-extrusion from three different materials may include a rigid core from Polystyrene (HIPS), a soft TPE for fingers or seals, and an SBC (Styrene-Butadiene Copolymer) skin later to increase the floss and aesthetic appearance of the profile.
