PERLITEMP is high temperature insulation, precision moulded into pipe and block shapes. Its principal ingredient- Expanded Perlite is one of the best of all the known naturally occurring Insulating materials. Its characteristic structure consists of millions off vitrified air cells. Through a proprietary process, these particles are bonded together with special inorganic binders and reinforcing fibers, moulded baked. Perlitemp conforms to ASTM C-610 Standard.
