Coroplast
Description
[PEL] A brand name for a rigid corrugated plastic board sandwiched between two sheets of thin Plastic. Coroplast® is composed of a high-impact copolymer of Polypropylene and Polyethylene. The moisture repellent sheets are light, strong, and acid-free. Coroplast® boards are used for enclosures, frames, backing, and supports. Chemically, the sheet is inert, with a NIL 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. All Coroplast® twin-wall profile sheets can be modified with additives, including UV protection, anti-static, flame retardant and color.
