Abstract:
1. A thermal insulator comprising: 10 to 84 wt % of expanded perlite containing an amount of 50 wt % or more of a closed cell expanded perlite based on a total weight of expanded perlite manufactured by expanding a raw ore of perlite, 15 to 85 wt % of a liquid binder and 0.25 to 5 wt % of a reinforced wherein the expanded perlite has a bulk density in a range from 20 to 40 g/l and a particle size distribution, based on total weight of the expanded perlite, of: 15±10 wt % of particles with a size of more than 400 μm, 40±15 wt % of particles with a size of 250 to 400 μm, and 20±10 wt % of particles with a size of less than 160 μm.
