Minimize Boil-Off Rate During Shipment

Liquefied Natural Gas (LNG) takes up about 1/600th of the volume of natural gas in the gaseous state, making it more cost-effective to ship overseas. LNG must be kept at cryogenic temperatures (-163° C) to maintain its liquid state. If the LNG reaches its boiling point (-161° C) the gas will boil off. To minimize the boil-off rate (BOR), specially-designed shipping vessels are insulated with foam using our blowing agents.

Many LNG ship builders currently use foam insulation formulated with HCFC-141b. Enovate® 245fa, a non-ozone depleting HFC foam blowing agent, significantly improves insulation performance compared to HCFC-141b, HFC-365mfc or water-blown foam (see chart below).

Enovate 245fa in LNG Insulation Minimizes Boil-Off Rate

Lower thermal conductivity means better insulating value. Ships that use foam insulation formulated with HFC-245fa foam blowing agent experience up to 15% improved insulating power at -160°C than foams formulated with HCFC-141b, HFC-365mfc or water.
