Supergel is regarded as one of the most widely used colour filter ranges in the world. It is comprised of more than 75 colours and 15 diffusions that are engineered using Rosco’s exclusive body-coloured, polycarbonate extrusion process to offer the longest possible life under hot theatrical and film/TV light fixtures. This unique manufacturing process also provides Supergel with unsurpassed heat-resistance, colour-stability and flame-retardancy.
Supergel features Rosco’s distinctive body-colored extrusion process. The manufacturing of these filters begins by combining powdered resin and dyes to create a concentrated color “pellet.” This concentrated colorant and additional clear resin are then fed into an extruder where they are blended together under intense pressure and heat. The mixture is then pushed through a die, which forms it into body-colored, 24” (60cm) wide film.
