Due to its non-corrosive properties and resistance to moisture, perlite protects pipes and equipment while providing excellent insulation.
Overall Performance: Perlite is a good sound dampener and provides light weight, excellent thermal insulating capabilities for everything from cryogenic to high temperature industrial applications. At high temperatures Perlite is extremely resistant to water absorption.
Physical Characteristics: Perlite is also called Vermiculite insulation. It is a type of rock (volcanic glass) that is mined, crushed, heated and then expanded (4x to 20x original volume) to form an excellent inorganic insulating material. The typical density is 2 to 15 pounds per cubic foot, so it is an efficient lightweight insulation product. It does not support flame spread or smoke development.
Temperature Range: The service temperature ranges from cryogenic [-450° F (268C)] to furnace applications reaching 1800° F (980°C).
Environmentally Safe & Friendly: Perlite is asbestos free, resistant to mold, rot, and rodents, all natural, low toxicity, chemically inert, and poses no known health risks.
Fabricated Products: DI delivers perlite in blocks, curved segments, pipe coverings, and fittings in various sizes and thicknesses to meet your job site needs.
Reduced Labor Cost: DI fabricated products eliminate in-field fabrication time and cost, allowing you to focus on installation.
Applications: Pipe Insulation, Fitting Insulation, Tank heads, cryogenics, LNG, LPG, Chemical, Food, Refractory Bricks, Petrochemical, Steel Mills and Foundries, Cement Plants, Boilers and Industrial Furnaces.
