ASTM C1482-00e1

Standard Specification for Polyimide Flexible Cellular Thermal and Sound Absorbing Insulation

SCOPE
1.1 This specification covers the composition and physical properties of lightweight, flexible open-cell polyimide foam insulation intended for use as thermal and sound-absorbing insulation for temperatures from -328 up to +572o F (-200 and +300o C) in commercial and industrial environments.
1.1.1 Annex A1 includes faced polyimide foam as specified by the U.S. Navy for marine applications.
1.1.2 This standard is designed as a material specification and not a design document. Physical property requirements vary by application and temperature. No single test is adequate for estimating either the minimum or maximum use temperature of polyimide foam under all possible conditions. Consult the manufacturer for specific recommendations and physical properties for specific applications.
1.1.3 The use of an appropriate vapor retarder is required in all applications where condensation could occur and cause a decrease in thermal performance or affect other system properties.
1.2 The values stated in inch-pound units are to be regarded as the standard. The System International equivalents of the inch-pound units are given in parentheses for information only and may be approximate.
1.3 This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
Note 1—The subject matter of this material specification is not covered by any other ASTM specification. There is no known ISO standard covering the subject of this standard.
