What is perlite, and how is it used?

Perlite is a naturally occurring, volcanic glass mineral that expands when rapidly heated. This expansion process produces a lightweight, porous material that's used in various applications such as insulation, filtration, horticulture, lightweight aggregates, and more.

What is the difference between raw and expanded perlite?

Raw perlite is the original form of the mineral. When heated to approximately 1000°C, the glass structure softens and the water trapped within the mineral vaporizes, causing the perlite to expand up to 20 times its original volume. This expanded form is what's commonly used in various applications due to its lightweight and insulative properties.

How do I determine the right type of perlite for my needs?

The type of perlite you need depends on your application. For instance, horticultural applications typically use medium to coarser sizes of expanded perlite, while construction applications might use small to fine grades. Density is another factor that can be controlled for expanded perlite. By providing specific requirements on our contact form, we can help match you with the appropriate product.

How is the price of bulk perlite determined?

What are the typical packaging options for bulk perlite orders?

Bulk perlite is often shipped in super sacks (large bulk bags), small, 2-4 cubic foot bags, or even in bulk tankers or rail cars for very large quantities. The choice of packaging usually depends on the volume of order and the customer's storage capabilities.

Are there any storage considerations for perlite?

Perlite should be stored in a dry location to maintain its properties. Expanded perlite can absorb moisture if left exposed, which can reduce its effectiveness in certain applications. There are packaging options that allow for outdoor storage of certain grades.

How is the delivered perlite's quality ensured?

Our network of producers utilize in-process quality control checks and packaging and transportation methods that protect the integrity of the perlite. This ensures that it remains uncontaminated and retains its quality from source to destination.
