PRO PERL PERLITE POWDER

Perlite is not a trade name but ageneric term for naturally occurring siliceous rock. To make perlite insulation, perlite ore is crushed and segregated. Then it is heated to a point in its softening ränge where its volume expands some 4 to 25 times due to the 2 - 6 % combined water in the ore. When rapidly heated to above 870°C (1600T), the ore pops äs this water vapourizes, creating countless partial vacuum air pockets in the heat softened glassy particles which makes expanded perlite lightweight and an excellent insulator. Expanded perlite can be manufactured to weigh äs little äs 32 kg/m 3 (2 Ib/ft 3), making it t he ideal insulation for cryogenic tanks and coldboxes.
