Silicone Extruded Profiles

Extrusion is one of the most versatile and cost-effective methods for producing silicone components with a consistent cross-section along their entire length. Silicone extruded profiles — often referred to as “profiles” in industry terminology — encompass an extensive range of shapes including solid cords (round, square, rectangular), hollow tubes, U-channels, P-shapes, D-shapes, and fully custom geometries engineered to match your application’s exact requirements.

The extrusion process forces raw silicone compound through a precision-engineered die under controlled temperature and pressure, yielding profiles with smooth surface finishes, consistent dimensional accuracy, and excellent material homogeneity. This makes extruded profiles particularly well-suited for edge protection and trim applications, weatherstripping and door seals, cable and wire insulation sleeves, conveyor belt guide rails, gasketing cords, and decorative architectural elements where both function and appearance matter.

Unlike molded parts which require dedicated tooling for each shape iteration, extrusion tooling (dies) is relatively economical, making this process ideal for medium-to-long run lengths where continuous lengths of consistent profile are needed. Post-extrusion services include precision cutting, splicing/joining (for frameless gasket fabrication), adhesive backing application, and custom coiling or spooling for automated assembly feeding.

Available materials cover the full spectrum from standard Shore A 20–80 durometer compounds to specialized formulations including peroxide-cured, platinum-cured (for medical and food-grade applications), conductive, and flame-retardant silicones.
