Silver-white Vermiculite has excellent properties such as thermal insulation, freeze resistance, antibacterial, fire resistance, liquid absorption, soundproof, and so on. When calcined at 800-1000°C for 0.5-1.0 minutes, the volume can rapidly increase by 8-15 times, and even up to 30 times. The specific gravity after the expansion is 50-200kg/m3, the color becomes silvery-white, then loose expanded vermiculite is formed.

Silver Expanded Vermiculite is widely used in construction, metallurgy, chemical industry, light industry, machinery, electric power, petroleum, environmental protection, transportation, and other sectors. It is mainly used in construction, insulation, packing, agriculture, and horticulture abroad.
