Carpet Tile w/Nylon 6 Fiber, Polyolefin Backing, and Limestone Filler

Carpet products are commonly available as tile (aka. modular) and broadloom carpeting. Carpet products start as a yarn face, tufted into a primary backing. A precoat layer of latex, filler, alumina tryihydrate flame retardant and other additives is applied to the primary backing to bind a scrim stabilizing layer and a secondary backing layer. Despite their similar construction, carpet products are made with a variety of polymer, filler, and additive content. Yarns are commonly made with Nylon 6 or Nylon 6,6, but may also be made with polyester, typically polyester terephalate (PET). Primary backings are typically a woven polyolefin such as polyester or propylene, but secondary backings widely vary including woven polyolefin, polyurethane and vinyl foams, polyvinyl chloride (PVC), rubber and asphalt. Filler content within the precoat and some secondary backings also vary, including virgin and/or recycled limestone, fly ash (aka. calcium aluminosilicate glass), recycled glass, asphalt, and/or recycled carpet. Fly ash is the most commonly used filler in carpet backings, often bringing heavy metal content such as mercury into the carpet backing. However, the use of fly ash was excluded in this CP for those that specify no fly ash carpeting. Antimicrobial treatments are commonly used as components of the latex precoat, although their efficacy is controversial. Stain treatments are also commonly used across the market, though they are generally proprietary and technologies may be specific to the type of fiber used. Carpets may be installed by direct glue or with factory or site applied peel and stick adhesives. This CP represents a carpet tile made with stain repellant treated nylon 6 fiber, polyolefin backings, and limestone filler.
