Temperlite - General Information

Description:

Temperlite^® 1200° is a rigid, high temperature, water resistant molded perlite thermal insulation available in either block, pipe or molded fitting form. The product is a light gray material with dark flecks throughout the product for easy identification as an insulation which does not contain asbestos.

Uses:

The product has an application temperature range up to 1200° F, even under cyclic conditions. Its unique water resistant formulation makes it especially suitable for those applications up to 600° F where water incursion is a consideration and where cellular glass or other foam insulation have previously been the only viable options. The product binder is sodium silicate which is naturally high in silicate, making it the preferred choice for those applications where stress corrosion is a consideration. Because the material is resistant to moisture, it does not contribute to premature corrosion of a protective jacketing system.

Features and Benefits

Moisture Resistance:

At temperatures up to 600° F, Temperlite^® 1200° is extremely resistant to water absorption. Mechanical strength and thermal performance are preserved and the insulation will not act as a reservoir for jacket corrosion as is common with many other rigid insulations.

Corrosion Resistance:

Because Temperlite^® 1200° is high in silicates and is non-wicking, it will not cause or promote stress corrosion cracking of austenitic stainless steel.

Thermal Performance:

Temperlite^® 1200° provides excellent thermal insulating propertites throughout its full range of use. This thermal efficiency results in reliable temperature control for critical process operations.

Fire Resistance:

Temperlite^® 1200° will not burn or carry flame. It has a flame spread of zero and smoke developed of ten when tested per ASTM E 84.

Heat Stability:

Unlike some other rigid insulation, Temperlite^® 1200° will maintain its integrity and insulating efficiency even under conditions of soaking heat up to its full 1200° F recommended operating range.

Rigidity:

Temperlite^® 1200° is designed and manufactured to provide the strength required to withstand personnel traffic and other common installation and application abuses.

Ease of Fabrication:

Temperlite^® 1200° cuts easily and cleanly, minimizing fabrication time in the field and prolonging fabrication equipment life.
