Pearlescent sand is also a type of expanded perlite, which is produced by crushing and sieving acidic volcanic glassy lava (perlite) to a certain particle size, followed by preheating.

A white or light-colored insulating material made by high-temperature sintering. Its particles have a honeycomb structure, are non-toxic, odorless, non-corrosive, and non-rotten.

Flammable, acid and alkali-resistant. Can be made into products with various properties using different adhesives, characterized by light weight, good thermal insulation and sound absorption.

Rich in raw materials, affordable, safe to use, and easy to install, widely applicable in industries such as oil, chemical, power, construction, and metallurgy.

Ideal for agriculture and landscaping, offering excellent fertilization, water retention, sterility, and breathability.

This product has stable physical properties with uniform particles, internally loose and porous, free of impurities. In the explosives field, it primarily prevents the caking and hardening of high-powdered explosives, and significantly enhances the explosive performance of modified ammonium nitrate explosives. Multiple experiments have proven that adding a small amount of perlite to explosives improves their safety performance.
