Abstract: Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket.
