PRODUCT BULLETIN
PMC SP
PMC dihydrous calcium sulfates are ground fillers/extenders. Particle sizing is computer
controlled with air classifiers, thereby increasing the uniformity of the particulate. Our
unique processing technique e nsures that no oversize particles enter the product stream.
This allows for higher filler loading and/or lower working viscosities. Consistent product
uniformity, low moisture content, and economical pricing are inherent to all of PMC s
products.
