Carpet Manufacturing

Produced from high quality natural ores at 8 facilities in North America, Carmeuse’s milled limestone products are used in a variety of industrial applications offering affordable and versatile solutions including the manufacturing of carpeting.

Milled limestone, referred to as “filler” in the carpet industry, is blended with latex to form the adhesive backing on tufted carpet.  This adhesive holds the carpet fibers together.  The quantity of filler can be as high as 35% by weight.  Filler color is important as the end user prefers a white carpet backing resembling a clean and new product.   Increased carpet durability and lower manufacturing costs are achieved by using limestone filler in carpet backing.


Benefits of Milled Limestone in Carpet:

  • Lowers cost
  • Durability
  • Provides a clean look to carpet backing
  • Flame retardancy
