Pearlescent sand is a high-quality insulating material widely used in industrial equipment requiring efficient refrigeration or thermal insulation. It is primarily applied in liquefied natural gas (LNG) storage tanks, liquid oxygen/nitrogen storage tanks, air separation units, and low-temperature storage and transportation equipment.
In the LNG sector, pearlescent sand is used as an insulating layer filled between the inner and outer shells of storage tanks, effectively reducing cold loss and ensuring stable medium storage.
In air separation units and various low-temperature containers, its extremely low thermal conductivity and excellent flow-filling characteristics provide long-term and reliable thermal insulation for equipment. Additionally, pearlescent sand is commonly used in low-temperature insulation systems in fields such as petrochemicals and aerospace research.
