Perlite has excellent abrasive properties, making this mineral a key ingredient in the production of abrasive materials, specifically in the automotive sector
Perlite is derived from naturally occuring volcanic glass. Its particles contain tiny amounts of water which expand into steam to produce a foamed structure made up of lightweight spheroids. These perlite microspheres deliver weight reduction while improving insulation, mechanical strength and hardness for manufacturers of adhesive and sealants.
