Tufted Carpet Tiles
In the precoat, VINNAPAS® vinyl acetate-ethylene (VAE) polymer dispersions bind the tufted fibers to the primary backing, provide good fiber bonding (tuft bind) properties to the carpet, and impart good wear resistance properties.
Benefits:
- Low odor
- Low emissions
- Reduced flammability
- Desired stiffness and durability
- Good plasticizer resistance
- Good compatibility with other system components, e.g. PVC, bitumen
- Low tendency to curl or “dome” after installation
Applications:
- Tufted carpet tile backings
Multi-Layered Structure of Tufted Carpet Tiles
Nonwoven Fiberglass Layer
Provides dimensional stability.
Polymeric Compound Layer
PVC, bitumen or other. Primary function is to provide weight and dimensional stability.
Precoat
Formulated with VINNAPAS® VAE dispersions; filled with calcium carbonate (selected fillers) and adjusted with additives, e.g., dispersing agents or thickeners. The precoat fixes the fibers to the primary backing.
Primary Backing
Can be made from woven or nonwoven fabrics. Main function: carrier for fibers.
Carpet Face
Made from synthetic fibers, such as polyamide, polypropylene and polyester, or natural fibers, such as wool or sisal.
