EPTlcum powder/talc powEPTlow price for EPT Use
EPTlcum Powder is a unique organic mineral generate by means of verification amp good grinding. This item might be utilized in Paints, Beauty, Paper, Pharmaceuticals, FerEPTzers and many others.
EPTlc lubricity, fireplace resistance, acid resistance, insulation, high melting level, chemical inertness, very good masking EPT and soft, excellent gloss, strong adsorption potential, exceptional bodily and chemical homes, the crystal composition of talc is a layer, so it is straightforward to spEPT into flake development and EPT lubrication and if the Fe2O3 articles is quite high will reduce its insulation.
The principal part of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the method is Mg3 [Si4O10] (OH) 2. EPTlc beEPTs to monoclinic system. The crystal is bogus, six sides or diamond flakes, from time to time. Normally dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a little amount of impurities and has ligEPT environmentally friendly, ligEPT yellow, ligEPT brown or pale purple the cleavage airplane is Pearl luster. Hardness 1, specific gravity 2.7 ~ 2.8.
Actual physical Analysis:
Coloration is snow white
