Lamitex G10-CR and G11-CR Cryogenic Glass Epoxies

Lamitex glass epoxy grades ( G10, FR4 & G11) are the preferred insulation in the industry as they do not physically degrade at cryogenic temperatures. Many commercial cryogenic epoxies are rated at -55°C as a minimum operating condition due to test equipment limitation and not the materials actual capabilities. Lamitex cryogenic epoxy grades will operate well below -55°C including temperatures ranging from -155°C to -270°C of liquid helium. However, there is a measurable loss of mechanical performance properties at temperatures beginning at -55°C.

Lamitex G10-CR and G11-CR are not the same as the composite industry standard G10 and G11. Their moduli (Youngs, shear & bulk) increase under cold temperatures making them more brittle which in turn lowers mechanical properties as much as 20%. Lamitex cryogenic glass/epoxies, however, have lower moduli enabling them to perform well at the low temperatures of liquid gases.

G10-CR retains excellent electrical characteristics and physical properties at cryogenic temperatures from -270 °C to a continuous operating temperature of 140 °C. It has a low thermal conductivity value of 7.0 x 10-4 calories/second/cm2/ (°C/cm) making it an efficient insulator. This material meets NEMA G-10, MIL-I-24768/2, Type GEE and IEC-60893-3-1 EP GC 201.

G11-CR retains excellent electrical characteristics and higher physical properties that G10-CR at cryogenic temperatures from -270 °C to a continuous operating temperature of 180 °C. It has a low thermal conductivity value of 7.0 x 10-4calories/second/cm2/ (°C/cm) making it an efficient insulator. This material meets NEMA G-11, MIL-I-24768/3, Type GEB and IEC-60893-3-1 EP GC 203.
