Properties of the EPGC202CR laminate
Tests have shown that the laminate retains full structural integrity even after repeated exposure to liquid nitrogen and liquid helium. SEM analysis revealed no microcracks, and Charpy impact tests indicated an increase in impact resistance of up to 37% at low temperatures.
Mechanical stability
• Bending strength remains virtually unchanged after cyclic immersion in liquid nitrogen at approximately -196°C.
• Young’s modulus increases at cryogenic temperatures, resulting in greater laminate stiffness under harsh conditions.
Thermal conductivity and thermal expansion
• Thermal conductivity decreases as temperatures drop, making the laminate ideal for insulation in cryogenic systems.
• The coefficient of linear expansion is low, which minimizes the risk of material deformation under extreme conditions.
Possible applications
• Energy and gas industries: tanks, pumps, and electric motors for LNG, LPG, ethylene, oxygen, hydrogen, and helium.
• High-voltage electrical engineering: transformers, compensators, superconducting electromagnets.
• Aerospace: components for rockets, research stations, and research equipment.
• Extreme refrigeration: systems for very low temperatures.
EPGC202CR is a material that combines high mechanical strength, excellent insulating properties, and reliability under extreme conditions—an ideal choice for the most demanding industrial and research applications.
