Johns Manville Microlite® AA Unbonded is a lightweight, binderless insulating blanket designed for applications in which intermittent temperatures may reach as high as °F (538°C). Because of its binderless construction, Microlite AA Unbonded eliminates outgassing or binder vaporization in such applications as cold face insulation in thermal fabrications for aircraft engines or thermal insulation in solar collectors. Microlite AA Unbonded provides superior thermal and acoustic performance and withstands temperatures up to °F (538°C) for short-term exposure and up to 850°F (454°C) for continuous exposure.
Availability: Americas, United States, Asia, Canada, Europe
Temperature Limit: 850°F - °F
Weight: 0.05 psf
Standard Thickness: 1.0"

Johns Manville Microlite® AA Uncured insulation is manufactured using flame-attenuated borosilicate glass fibers bonded with an uncured thermosetting resin and provides superior thermal and acoustic performance. It can be molded into a wide range of sizes, shapes, densities and thicknesses to fit odd-shaped parts, special configurations and applications in which precise insulation fit is critical. After proper curing, the molded or sized insulation material is excellent for aerospace or high temperature equipment applications where space and weight are key considerations.

Johns Manville Microlite® B is a lightweight, flexible blanket manufactured using flame-attenuated borosilicate glass fibers and bonded with a thermosetting phenolic resin. The flame-attenuated process used in the manufacture of Microlite B provides uniformly distributed glass fibers with low heat transfer characteristics, excellent acoustic performance and high tensile strength. The resilient glass fibers prevent vibrational settling. Microlite B blankets are designed for applications where temperatures do not exceed 450°F (232°C).
