Charter Perlite Institute Member

Supreme Perlite is a longtime member of the Perlite Institute, a worldwide association of perlite expanders, miners and applicators. The Institute develops product standards, conducts studies on various perlite-related subjects and facilitates discussions between members on product and processing issues around the globe.

We regularly contribute to the work of the Institute by participating on committees and serving on the Board of Directors. This commitment ensures we can offer our customers the latest in innovation and product knowledge to better serve their respective industries.
