CHARACTERISTICS
Vermiculite is a naturally occurring mineral that is used both as raw vermiculite in various grain sizes and as a further processed material. Our vermiculite bagged goods are available in four grain sizes. For the production of panels and molded parts, exfoliated vermiculite is mixed with special binders, if necessary with other additives (e.g. ash, lime), and pressed into panels or molded parts and then dried.
