20 micron talc

In conventional chemical pulping systems, micronized talc is used for pitch control. The mechanism is not well understood, but talc does adsorb on the pitch and detackify it, preventing it from agglomerating and attaching on equipment. In de-inking talc is used both to enhance ink removal in conventional screening/centrifugation methods and as a carrier in flotation systems. 

The process by which a solid is reduced to particle sizes of less than about 100 pm by using any type of particle-size reduction equipment. Examples micronized talc, micronized pigment.

Compounds with more finely micronized talc particles show less tendency to be visibly scratched than compounds with standard, coarser talcs. Talc particles can also be surface-treated to improve a compound s scratch resistance. Both of these factors can also improve the performance of anti-scratch additives [17-6].

The talc used in filled PP experiments was CIMPACT 710, a nonsurface-treated micronized talc, with an average particle size of 1 (xm, from Luzenac America. 

The PP base resin used was a 35 MFR ICP resin containing 9% ethylene. The filler was a nonsurface-treated micronized talc, with an average particle size of 1 j,m. The modifiers used were the standard EB Plastomer and EPR. An extreme vertices mixture designed experiment was used (30). The three ingredients were subject to high and low percentage constraints ...

Certain raw materials can be coated (talc, mica, serecite, pigments, pearls, etc.) or micronized (talc, mica, serecite, pigments) to modify or amplify an aspect. Globally speaking, they may facilitate pigment dispersion, compacting, skin adhesion, softness and wet and dry apphcation. 

Figure 51 shows the effect of adding talc (7 microns), Group C, to a coarse sea sand (165 microns), Group B. The beneficial effect of the fines on the fluidizing characteristics is shown to increase to a fines composition of around 25%, and then it diminishes with further fines addition. 

Several micron-sized layered silicates, such as talcs, can improve the fire retarding behavior of EVA by partial substitution of metal hydroxides. Clerc et al.63 have shown that better fire performance was achieved using higher values of the lamellarity index and specific surface area for four different types of talcs in MH/EVA blends. Expanded mineral and charred layers were formed, similar to intumescent compositions with APP, proving the barrier effect on mass transfer, even at the micron scale for the mineral filler.
