Notes
CalTalcs are high purity, high brightness materials characterized by a platy grain shape and closely controlled particle size. They are excellent for use in a wide variety of products including ceramics, paint, coatings, paper, plastic, putty/joint compounds and rubber products. CalTalcs emcompass a series of products ranging from 200 mesh to 3 microns.
Grade 200 325 Micro MicroPlus
Specific Gravity: 2.75
Weight per solid Gal-lb: 23.3
Loose density lb/ft3 29 28 16 12
Tapped density lb/ft3 62 57 40 27
Plus 325 mesh 14% 1% trace NIL
Dry Brightness 88 88 90 90
Oil Absorption 20 28 33 36
