PETROLEUM WAX IN IMPREGNATED PAPERS


Provider: TAPPI

Price: $35.00
Product Details

This method determines quantitatively the total amount of petroleum wax in impregnated papers, including both “dry waxed” and so called “waxed paper” constructions. The wax is extracted with hot trichloroethane, which is then removed by evaporation, and the wax weighed.

The method is not intended for wax-sized papers, because these generally contain such quantities of rosin or other soluble matter as to impair its accuracy. Neither is it intended to determine surface wax on waxed paper or

paperboard, for which TAPPI T 497 “Surface Wax on Waxed Paper or Paperboard” (withdrawn in 1985; former wax testing method available from the American Society for Testing and Materials) is applicable.
