Thermal Insulation, Refractory, Building Energy Saving

Expanded Perlite is an incredibly versatile and environmentally friendly inorganic lightweight insulation material. It has a myriad of excellent properties, including being lightweight, insulating, thermally insulating, and fireproof. Additionally, it has advantages like non combustion,   high   strength,   low   water   absorption,   good   accessibility,   and   a   long   service   life. This product is made from specially selected particle-size   mineral   sand,   which   is   then   expanded   under   electric   furnace   heating.   Through   precise   control   of   temperature and raw material stagnation time, the surface of the product is melted, forming irregular spherical particles. The internal porous cavity structure has a glassy closed surface, smooth luster, and very stable physical and chemical properties. This product can be used as a lightweight aggregate in the new building materials industry, as a substitute for floating beads in the lightweight refractory material industry, and as a substitute for glass microspheres in the emulsification industry.

It has extremely broad application prospects and can be widely used in many fields such as industry, agriculture, building materials, chemical industry, smelting, light industry, and more. Due to the formation of certain particle strength through surface vitrification, the physical and chemical properties are very stable, with strong aging and weather resistance. Perlite has excellent insulation, fire prevention, and sound absorption properties, making it suitable for use as lightweight filling aggregates and insulation, fire prevention, sound absorption, and insulation materials in many fields. In the building materials industry, using vitrified microspheres as lightweight aggregates can improve the flowability and self-resistance of mortar, reduce material shrinkage, improve product comprehensive performance, and reduce comprehensive production costs.
