ABSTRACT:
Thermoplastic resin powders of cellulose acetate esters in which essentially 80% or more of the particles pass through a 100 mesh screen (U.S. Sieve Series) and essentially 50% pass through a 200 mesh screen (U.S. Sieve Series) are desirable and useful as a filler material for investment casting waxes. The cellulosic thermoplastics resin powders are environmentally safe when used as filler material for investment casting wax compositions since the powders produce essentially no carcinogenic materials on combustion. The powders are as effective as acid fillers and set relatively fast thus improving cycle time in the die but do not produce an adverse effect of shell cracking nor react with the slurry.
