. Manufacturers typically offer a wide variety of colors, thicknesses (quite commonly 3, 4, 5 mm), and weight (measured in grams per square meter, or GSM). Chemically, the sheet is inert, with a neutral pH factor. At regular temperatures most oils, solvents and water have no effect, allowing it to perform under adverse weather conditions or as a product component exposed to harsh chemicals. Standard sheets can be modified with additives, which are melt-blended into the sheet to meet specific needs of the end-user. Special products that require additives include: ultra-violet protection, anti-static,

. Corrugated plastic is widely used in various industries due to its lightweight, durable, and versatile nature. Some common applications include: Temporary Surface Protection: Corrugated plastic is frequently employed in residential, commercial, and mega yacht settings to protect floors, walls, and other surfaces during new builds, repairs, and remodeling projects. Its durability and ease of installation make it an ideal choice for safeguarding against damage from heavy foot traffic, tools, and construction debris. Dust Containment: In addition to surface protection, corrugated plastic is also used to create dust containment barriers in construction and remodeling environments. It helps in maintaining clean workspaces and protecting sensitive areas from dust and debris. Companies lik
