Multiperl® comes from a volcanic rock, generic name is Perlite. Of siliceous composition differs from other volcanic rocks due to its property to expand from 4 to 20 times its volume when heated to softening point.
Is a form of natural glass that is classified as chemically inert and with an approximate Ph of 7. Making use of this property to create PremiumPerlite®, the material is submitted to a controlled process under granulated, density and temperature conditions using a specific formula to obtain the adequate abrasiveness and softening on textile treatment.
Multiperl F® Cryogenic grade is expanded mineral Perlite of low density, ideal to be used and a thermo sealant material mainly used in cryogenic facilities to store liquefied gases.
