Advantages

• Microlite® AA Blankets offer superior acoustic and thermal performance per unit weight of insulation used.
• AA blankets are phenolic bonded, noncombustible, and easily meet the most stringent smoke density, smoke toxicity and total heat release standards.
• Because Microlite® AA Blankets are non-cellular and moisture-resistant, they will not support biological growth or vermin.
• They also provide excellent stability with age.
• The exceptional resiliency of the glass fibers prevents vibrational settling and retains their excellent sound attenuation and thermal properties.

Properties

• Superior Acoustics
• Water Repellent
• Low Heat Transfer
• Biosoluble Chemistry
• Noncombustible
• Excellent Dimensional Stability
• Exceptionally Low Smoke and Toxicity

Aerospace Applications

Applications

• An additive is used to provide water repellency to the cured blanket for service in areas where high-altitude moisture condensation may occur.
• In circumstances where moisture is not a concern, plain phenolic binder can be specified.
• Formed from resin bonded borosilicate 902 biosoluble glass fibers, Microlite® AA Blankets provide optimum thermal and acoustical insulating performance for applications up to 450°F.
• These blankets help control thermal and acoustical transmission in a variety of aerospace applications, and are particularly well suited for insulating the fuselage wall cavities of commercial and private aircraft.
• Aerospace
• Fuselage Wall Cavities of Aircraft
