Perlite

What’s Perlite?

The perlite original sand is finely ground and finely pulverized for use in rubber and plastic products, pigments, paints, inks, synthetic glass, insulating bakelite and some mechanical components and equipment for filling.

The perlite is expanded to become a lightweight, versatile new material. It has the characteristics of low apparent density, low thermal conductivity, good chemical stability, wide temperature range, low moisture absorption capacity, non-toxic, odorless, fireproof and sound absorbing. It is widely used in various industrial sectors.
