ite, Ultra-Lightweight Aggregate Expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 5mm in size. It is inorganic, inert, neutral in pH, biologically stable and has no asbestos content. It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C. It also has a highly adsorbent surface and a very low bulk density which makes it an ideal carrier or low cost filler for many compound formulations. What is Perlite? Perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 5mm in size What can it be used for? Perlite is widely used in commercial hydroponics, seed starting and plant rooting, as a soil conditioner, and to enhance the water-holding and anti-compaction properties of growing soils. What grades are available? Perlite can be supplied in a number of grades, dependant on the particular requirements of the application. SwiftAir Perlite is 2-5mm Applications Cryogenic Non-combustible ultra-lightweight mineral aggregate with excellent insulation & adsorption properties. Absorbent Silvaperl’s exfoliated vermiculite and expanded perlite are absorbents and carriers. Each of these unique minerals have their own characteristics. Castables Perlite insulation is used in high temperature applications in the steel and foundry industries such as ladle topping, hot topping and risering. Cavity Fill Silvapor coated expanded perlite is a hydrophobic insulating aggregate.

- UK GROW Perlite is a natural soil mineral used to prevent water loss & soil compaction, use for seed starting, amending potting mixes & rooting cuttings. Perlite has been heated at high temperature causing it to expand by up to 15 times. This creates a porous structure to store both air and water.

- UK GROW Perlite is a naturally occurring mineral in the form of amorphous volcanic glass, although its often confused by new gardeners as being some lightweight material like styrofoam. Its occasionally called expanded pyrite and has the nickname volcanic popcorn, and Ill get into why in the next segment. If you looked at a piece of horticultural perlite under a microscope, you would see that its quite porous.
- Airflow in the soil is greatly improved in a bed amended with perlite, and thats necessary both for your plant roots to breathe and for any worms, beneficial nematodes, and other good natural garden inhabitants. Because its a mineral glass and thus harder than the soil around it, it also helps to slow down compaction, and keeps your soil fluffy and lightweight.
