Cryogenic G-10 (YL3849) is a high-performance glass fabric reinforced epoxy composite designed for cryogenic service from -196°C to 130°C (up to 155℃ upon request). It is based on a halogen-free epoxy system that provides excellent electrical insulation, low thermal conductivity, and strong mechanical stability at ultra-low temperatures.
It is optimized for LNG and other cryogenic applications where reliable thermal isolation and structural integrity are required. It maintains stable properties under high humidity and continuous cryogenic exposure.
G-10 CR is widely used in LNG piping systems under -196℃, storage equipment, and aerospace cryogenic structures. It is available in both sheet and tube form (YL3848) for machining into precision insulation components.
Note: This material is not flame retardant.
