... or area of interest. A disadvantage is that these materials soften if frictional heat is generated during grinding or polishing. Shrinkage is high, producing gaps and poor edge retention. Some problems with chemical resistance may be encountered, since the thermoplastics are attacked by strong acids...

.... An attack-polish procedure may also be used. Initial polishing is performed using Al 2 O 3 abrasive on a short-nap cloth at 1750 rpm. A 5 to 10% aqueous oxalic acid solution is used with the Al 2 O 3 to achieve simultaneous chemical attack and mechanical polish. Final polishing is then performed using γ...
