Expanded perlite is a widely-used inorganic mineral material, encompassing nearly every field. For instance:
Oxygen generators, cold storage facilities, and liquid oxygen/nitrogen transport use it as fill-in thermal insulation material.
② Used for filtration of products such as alcoholic beverages, oils, pharmaceuticals, food, and wastewater.
③ For rubber, paint, coatings, plastics, and other fillers and expanders.
④ For sensitizers.
⑤ Used for adsorbing floating oil.
⑥ Used in agriculture, horticulture, soil improvement, and moisture and nutrient retention.
⑦ Used in conjunction with various adhesives to produce a variety of profiles with different specifications and performance.
⑧ Significantly more quantities are used for thermal insulation and heat preservation on industrial kilns and for the roofs and walls of buildings.
