Unbonded Microlite® B Blanket



Unbonded Microlite® B Blanket is a lightweight, binderless insulation blanket designed for thermal and acoustical applications in which intermittent temperatures may reach as high as 1000°F (538°C). This loosely felted, non-resilient blanket is formed from flame attenuated borosilicate glass fibers without binders and oils and is not dimensioned by thickness.


Unbonded Microlite® B Blanket eliminates outgassing or binder vaporization in such applications as cold face insulation in thermal fabrications for aircraft engines or thermal insulation in solar collectors. In all applications Unbonded Microlite® B Blanket provides excellent thermal and acoustical performance.


Unbonded Microlite B blanket provides low heat transfer as well as exceptional sound absorbing characteristics. Is adaptable to flat, curved and irregular surfaces and are readily cut with ordinary tools.
