Product Description

The correx fire rating/frame retardant correx sheets are produced from high-impact polypropylene resin with a similar make-up to corrugated fiberboard. It is a lightweight tough material that can easily be cut with a utility knife and is non-toxic, and recyclable.

Chemically, the sheet is inert, with a neutral PH factor, and has exceptional strength and durability. 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 the specific needs of the end-user. Special products that require additives include ultra-violet protection, anti-static, flame retardant, custom colors, conductive, etc.

The sheet is very versatile and could be used for many different purposes. The popular usages are as follows.

  • Corrugated plastic boxes - For the manufacture of reusable logistic boxes, packaging boxes for various products.

  • Coroplast signs - The sheets wildly use in screen printing for advertisement, typically used in the signwriting industry for making signs for real estate sales, construction sites, promotions, political campaigns, etc.

  • Layer pads/Tier sheets - Used for the separation of glass or PET bottles, metal cans, and blown plastic containers in many beverage and food manufacturers, due to its hygiene and dust-free, correx fire rating is the best alternative to cardboard separators and effectively reduces costs.

  • Correx floor protection - Temporary protection for floor and wall during interior decoration.
