►Origin and Characteristics:
►Perlite is not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume.This expansion is due to the presence of two to six percent combined water in the crude perlite rock.
► There are many uses for perlite. These uses can be broken down into three general categories and applications
► Expanded perlite can be manufactured to weigh as little as 2 pounds per cubic foot (32kg/m3) making it adaptable for numerous applications. Since perlite is a form of natural glass, it is classified as chemically inert and has a pH of approximately 7

► This expansion process also creates one of perlite's most distinguishing characteristics: its white color. While the crude rock may range from transparent light gray to glossy black, the color of expanded perlite ranges from snowy white to grayish white.
► Virtually all grades of material are available including specialty grades developed for individual customers. With quality control second to none we can assure consistent material to meet your requirements
►When quickly heated to above 1600°F (871°C), the crude rock pops in a manner similar to popcorn as the combined water vaporizes and creates countless tiny bubbles which account for the amazing light weight and other exceptional physical properties of expanded perlite.
► Perlite the Wonder Rock has many applications in industry and construction.
