perlite mining is 1499 (miscellaneous nonmetallic minerals, except fuels), and the SIC code for perlite processing is 3295 (minerals and earths, ground or otherwise treated). The six-digit Source Classification Code (SCC) for perlite processing is 3-05-018. Expanded perlite usually has a density in the range of 112 to 240 kilograms per cubic meter
Get PriceIn its expanded form, vermiculite has a very low density and thermal conductivity, which makes it attractive for use as a soil amendment, lightweight construction aggregate, and thermal insulation filler. Expanded vermiculite also has a very large chemically active surface area, which makes it useful as an absorbent in some chemical processes.
Get PriceFeb 14, 2012 · Vermiculite absorbs water, so the commercial mix is probably treated with something to avoid water retention. Perlite does not absorb water, but concrete grade perlite, (small sand size granules) seems hard to find. I found some but I will have to drive to the perlite processing plant 100 miles away to get it.

Get PricePerlite is a generic term for naturally occurring siliceous rock. It is a form of natural glass which like pitchstone, obsidian and other similar contains "combined water". Perlite (containing 1,9% – 4,8% wt. "chemical" or combined water) was formed over a few million years by the chemical weathering of obsidian at the earth's surface.

Perlite mets, expands and attain an extremely porous surface, increasing its volume by 10-14 times. It result in superior thermal insulation and sound proofing properties, as well as in extreme lightness (weights 32-40kg/m3). As volcanic glass, perlite is non-flammable.
Get PricePeople have had problems finding vermiculite because of two reasons: In the early 1990's the W.R. Grace Company closed its mine in Libby, Montana and over 20 processing plants located across the country. As a result, there are many regions where there simply isn't a local vermiculite processing plant.
