Insulation system

Armacell's new low density thermal elastomeric foam insulation product is said to retain flexibility even at cryogenic temperatures of -200°C.

Processes which use such low temperatures and require technical thermal insulation materials include freeze drying of foods, metal alloy production using liquid nitrogen, and manufacture of some chemicals and pharmaceuticals.

Another area is the freezing of large volumes of natural gas down to condensation temperatures (-162°C), with the resultant liquid gas having a reduced volume of less than 0.17% of the gaseous product. Armacell insulation maintains the cryotechnical validity of this process - from initial production to final regasification where gas is fed into pipework for distribution to market.

Armaflex LTD has an upper temperature thermal limit of 125°C, which ensures internal surfaces of pipework, tanks and vessels can be safely subjected to steam or high temperature chemical cleaning.

Products maintain full strength and flexibility over the range -200°C to 125°C. This ensures vibration and impacts can be absorbed, with the risk of cracking reduced. ArmaSound insulation can also be incorporated.
