KREBS UNITS (K.U.)

 

k-FACTOR: Thermal conductivity for a unit thickness of material. Expressed as W/m2•K (Btu•in./hr•ft2•F). R-VALUE is equal to the thickness of the material divided by the k-factor (R = x/k where x = thickness). (See R-VALUE.)

KNIT LINE: A high-density skin formed between one lift or pass of foam and another. Synonymous with LIFT LINE.

KREBS UNITS (K.U.): A measurement of viscosity for materials that have the property of changing resistance to flow when under shear. Such materials are called THIXOTROPIC. Measuring is accomplished with a Krebs/Stormer viscometer. (See also THIXOTROPIC.)
