Refractory material "Vermiculite"

It has the property of expanding when rapidly heated at high temperatures, and its various other features are being utilized in various fields such as agriculture, horticulture, and construction!

"Vermiculite" is a mineral primarily composed of silicon oxide, magnesium oxide, and aluminum oxide, and it resembles mica in appearance. When it passes through a high-temperature (800–1,000°C) furnace, the moisture contained within the crystal layers instantaneously turns into steam, causing the layers of the raw material to delaminate and expand rapidly in an accordion-like manner, increasing its volume by several times. This is known as "expanded vermiculite." 【Features】 ■ Water Retention: Capable of holding a large amount of moisture in the accordion-like gaps. ■ Sterile: Treated at high temperatures, making it sterile and clean. ■ Cation Exchange Capacity: Due to its high cation exchange capacity (CEC), it can retain many bases (nutrient components). ■ Fire Resistance: It has an exceptionally high fire resistance with a melting point of over 1,300°C. ■ Insulation: It possesses high insulation performance. *For more details, please refer to the PDF document or feel free to contact us.
