With its dual attributes of broad diffusion and a warm center, the Roscolux Tough Frost 20x24" Sheet of Light Diffusing Material from Rosco is a top-tier choice for professionals in the photography and film industry. This product is part of Rosco's esteemed Roscolux range, which is renowned globally for its longevity, even under the intense heat of theatrical lights. The Roscolux Tough Frost is crafted using a unique tri-extrusion process, which combines three distinct layers. The colored layer is securely sealed between two ultra-thin layers of clear film, significantly reducing dye migration and extending the product's effective lifespan. Known as "Supergel" in international markets, Roscolux is currently the most widely utilized filter range worldwide.This light diffusing material is composed of two types of plastic. Over 65% of the product is made from co-extruded polycarbonate plastic, while the rest is deep dyed polyester. Unlike ordinary color filters that are manufactured by surface coating clear polyester plastic film, Roscolux's color is not merely painted onto the surface. This unique manufacturing process ensures that the dye is resistant to heat and physical abrasion, preventing quick fading and scratching.The Roscolux Tough Frost is available in sheets of 20in. X 24in. (50cm x 61cm) or rolls of 24in. X 25ft. (61cm x 7.62m). For those requiring larger dimensions, the Cinelux line of filters offers rolls of 48in. X 25ft. (122cm x 7.62m). Th
