Types and Suggestions
 We have both crude vermiculite and exfoliated vermiculite in two types: one is Silver-grey type ( Fe2O3 content around 5-8%, similar with South Africa vermiculite); the other type is Golden-yellow type (Fe2O3 content around 16-23%, similar products with India and Australia).The white type mainly used in refractories/insulations, the golden yellow type mainly used in agriculture and horticulture. If used for agriculture and horticulture, we suggest you use golden vermiculite, because its PH is 6.5-7.2, for silver gray vermiculite,its PH is 8.5-9.5, that's to say, golden vermiculite is more neutral. In Japan, Korea market, our customers choose golden vermiculite used for agriculture and horticulture .
