Carpet Testing
Dimensional Stability
Latex Solids
Latex Solids: A water emulsion of synthetic rubber, natural rubber, or other polymer. In carpet, latex is used for laminating secondary backings to tufted carpet, backcoating carpet and rugs and for manufacturing foamed cushion. almost all carpet latex consists of styrene-butadiene synthetic rubber (SBR) compounded with large quantities of powdered fillers. The latter are most often whiting, which is a calcium carbonate.
Latex Filler Load
(double ash method)
Latex Filler Load: A low cost material used for extending rubber, plastic, or other polymers. Fillers are generally powders of very small particle size. Carpet latex laminating compounds and foams contain large amounts of fillers. The most common filler in carpet latex is finely powdered calcium carbonate, often called whiting, produced by grinding limestone.
PH
PH: The chemical symbol indicating the negative logarithm of the effective hydrogen ion (H-) concentration or activity (parts, %) in gram equivalents per liter: an indication of relative acidity or alkalinity. A ph of 7 is neutral (distilled water), whereas numbers above 7 to 14 indicate increasing alkalinity, and numbers below 7 down to 0 indicate increasing acidity.
