Microsphere Insulation for Cryogenic Systems

Microspheres (Glass Bubbles)

Under development by TAI as a cryogenic insulation material, microsphere insulation is an evacuated powder consisting of hollow glass bubbles. (Patent pending)

Benefits

	Competitive thermal performance even at soft vacuum
	Low density yet has high crush strength
	Load bearing capability allows thin vacuum jacket
	Fluid-like behavior fills voids but does not compact
	Easily installed, low cost, robust insulation system

Applications

	Cryogenic storage tanks (perlite replacement)
	Vacuum-jacketed transfer lines for new and field service of existing lines
	Insulation panels that can be fabricated to insulate components with complex shapes
