1 Micron = 1000 NanoMeters. Note the size range of viruses in this chart… .005 – 0.3. The .005 is much smaller than many water filters claim to remove! What is important to remember is the size of viruses that have proven to be harmful or deadly to humans.
Talc is the word's softest mineral. Although all talc ores are soft, platy, water repellent and chemically inert, no two talcs are quite the same. Talc is a vital Part of everyday life. The magazines we read, the polymers in our cars and houses, the paints we use and the tiles we walk on are just some of the products that talc enhances.

Talc is a clay mineral made of hydrated magnesium silicate. Talc is formed from metamorphic reaction of minerals in aqueous conditions. Talc is one of the softest minerals on earth, with a Mohs hardness of 1.0 (defining mineral). However, some abrasive impurities (such as quartz or sand) may be present in the mined talc…
This felt offers better resistance to acids and alkalies than standard filter felt.. Select felt based on the size of the particles you wish to remove. For example, the particle size of flour is about 100 microns and talcum powder is about 10 microns. View more information on particle size in microns.
Low abrasion: Talc is the softest industrial mineral with a Moh's hardness of 1. Pure, chlorite-free Talc products give the low abrasion values which lead to a long tool life in compounding and extrusion. Thermal conductivity: Talc filled compounds have a significant higher thermal conductivity than the polymer. Heating and cooling are ...
Since the filler costs less than the compound the more one adds the lower the formulation cost. The amount that is added is determined by the physical requirements of the product. In this situation the fillers are usually 5 microns or larger and will have a negative effect on …
