BACKINGS - CLASSICBAC PC ™

When Performance Is Critical, Get The Backing With More Face Value.

In specifying carpet for extra heavy commercial traffic areas, the backing that can make a critical difference in the carpet’s ability to perform. The ultimate high-performance attached cushion backing system is ClassicBac PC ™. ClassicBac PC ™ is an 18 lb. density attached polyurethane cushion composite that is applied to the back of commercial carpets at the manufacturing level. Specifically engineered for use in public spaces that receive heavy foot and roller traffic, ClassicBac PC ™ is designed for hospitals, airports, banks, hotels and casinos. It can be applied to all styles and constructions, including multilevel tufted graphics, wovens and Axminsters.

APPEARANCE RETENTION

Its mechanically-frothed polyurethane formulation supports the face yarn construction and helps carpet retain its original appearance longer, extending the useful life of the carpet. In fact, repeated roll stool tests, simulating heavy commercial traffic, indicate that ClassicBac PC ™ can add years of performance in the most demanding environments.

COMFORT and PERFORMANCE

ClassicBac PC ™ provides more comfort underfoot than unitary backings in direct glue down installations. With its superior dimensional stability, ClassicBac PC ™ virtually eliminates edge raveling and delamination. It also resists moisture penetration. Because the cushion is already attached to the carpet, it is faster and less troublesome to install than double glue down methods, and it outperforms carpet and separate pad in heavy traffic situations.

TECHNOLOGICAL ADVANTAGES

Advanced polyurethane backing technology, drawing on more than two decades of floor covering research, also gives ClassicBac PC ™ these additional advantages over other commercial carpet backings:

1. Its unique construction is designed to maintain the dimensional integrity of the finished carpet, to resist buckling, curling, stretching or shrinking.


2. The fine mesh, synthetic lino-weave scrim backing creates the perfect substrate for releasable flooring applications, making it easier to install and remove. It also shields the cushion from adhesive saturation. By blocking the adhesive from wicking up into the backing, less adhesive is needed for a secure installation-permanent or releasable.


3. ClassicBac PC ™ surpasses other attached backings when it comes to gauge control, a critical factor in seaming. Gauge variations previously associated with attached cushions are virtually eliminated with Textile Rubber & Chemical Company’s patented belt technology. By precisely monitoring the foam application during the manufacturing process, overall tolerances of the composite carpet are set not to exceed plus or minus 15/1000 of an inch, which is almost indistinguishable. This ensures that the gauge of the backing will remain constant from side to side, end to end, and roll to roll.


4. As a completely synthetic composite, ClassicBac PC ™ inhibits deterioration with age. It effectively resists odor-causing mold and mildew, and withstands harsh wet or dry cleaning procedures.

STANDARD SPECIFICATIONS

ClassicBac PC ™ is an 18 lb. density, mechanically-frothed polyurethane cushion/scrim composite that is applied to the back of commercial carpets at the manufacturing level. It can be applied over a pH adjusted unitary latex or polyurethane unitary precoat as well as an ClassicBac™ secondary. It is compatible with carpets in 12' and 6' widths. These standard specifications are subject to slight variations within normal manufacturing tolerances:

 

TYPICAL PROPERTIES

Typical properties are derived from averages under standard manufacturing conditions and are affected by carpet fiber, weight, construction, humidity and temperature. These properties may vary within normal industry standards. Performance is not affected by such variances.
