What's Europerl Perlite ?

Perlite is the name of a naturally occurring volcanic rock. With a specially heating Perlite expands and then it's called Europerl Perlite. With heating at 1100°C it expands up to 20 times of its original volume and it's now a white sterile lightweight aggregate with many great properties. Perlite has been used more than 65 years in all over the world. Europerl Perlite is a clean product without any chemicals. Each particle contains countless of tiny glass-like bubbles.
