Please find our product details below:vermiculiteVermiculite is a natural mineral that expands with the application of heat. The expansion process is called exfoliation and it is routinely accomplished in purpose-designed commercial furnacesperlitePerlite is a naturally occurring siliceous volcanic glass lava containing combined water, falling into the category of igneous rock.Sell various of micaBecause of high insulation strength, acid-base corrodibility resistance, elasticity, tenacity, heat-resistance, sound insulation, and strong adhesive force, muscovite can be used in many industries such as electric insulation, heat insulation, paint plastic, rubber, ceramic, petroleum, drilling, electric welding rod, cosmetic and space navigation.SellWhen subjected to heat, vermiculite has the unusual property of exfoliating or expanding into worm-like pieces. This characteristic of exfoliation, the basis for many commercial uses of the mineral, is the result of the mechanical separation of the layers during the rapid conversion of contained water into steam. The increase in bulk volume of commercial grades is 8 to 12 times, but individual flakes may exfoliate as many as 30 times the original size. There is also a color change during expansion that is dependent upon the chemical composition of the vermiculite and the furnace temperature. The bulk density of crude vermiculite or vermiculite concentrate is in the range of 640-1120 kg/cubic meter. (40-70 lb/cubic foot) and exfoliated or expanded vermiculite is in the range of 64 - 160 kg/cubic meter (4 - 10 lb/cubic foot)Thank you for taking time to go through our business profile.
