Low in density, high in use

摘要

EXPANDED PERLITE has a wide range of end uses which take advantage of its many useful qualities, including construction, horticulture, and filtration applications. Perlite can even act as a filler. Its beneficial properties include a low density, good insulating characteristics, inertness, non-combustibility, and good absorption capacity. Perlite production is dominated by Greece and the USA, which are home to some of the perlite industries leading lights: Athens-based S&B Industrial Minerals; World Minerals Inc., based in Lompoc, California; and Grefco Minerals Inc., Bala Cynwyd, Pennsylvania.
