Glass Fiber From Yellow Thermal Blanket Insulation

Transmitted Off Cross Polarized Light Illumination

Definition/Function:

Significance in the Environment:

Characteristic Features:

The smaller quantity of phenolic resin used to hold thermal blanket insultion together is distributed more easily when it has a low viscosity. Mineral fillers would interfer with that distribution. As a result, the resin is clear with few inclusion. The total amount of resin on the fibers is also lower than in the case of acoustic ceiling tiles or ventilation system soundboard, whose resin systems contain mineral fillers.
