Perlite is the generic name for naturally occurring siliceous volcanic rock.
AUSPERL is pleased to offer two grades of ore from which expanded products are produced.
Australian sourced perlite is very old in comparison to other resources.
As a result when popped it is harder and more resilient than younger, softer ores making it particularly useful for horticultural applications.
New Zealand sourced is its extremely young age relative to other global resources. This allows for greater expansion and yield nearing the maximum of up to 25 times its original volume when heated to its softening range.
Alternately due to its young age, the ore expands with lower energy requirements allowing for more cost effective processing.
The expansion process is caused by the presence of water in the crude rock. When ore is rapidly heated to above 850°c this water vaporizes and causes the softened rock to expand. Tiny glass-like bubbles are produced which account for the lightweight and exceptional physical properties of expanded.
