Temperlite® insulation sectionals in the form of pipe covers and boards consist of expanded perlite powder bound together by an inorganic binder (sodium silicate) and reinforcing fiber. Completely non – flammable, they are widely used as insulation for heated equipment, vessel, and piping. The major advantages that perlite insulation sectionals have over the 2 main competitors, calcium silicate and rock wool are:-
Temperlite® insulation sectionals have a high sodium silicate -to- chloride ratio. Sodium silicate is a corrosive effect of soluble chlorides. The water – repellent nature of perlite prevents the entry of soluble chlorides into the system. This helps avoid unnecessary shutdowns and loss of production hours at refineries, petrochemical, and power plants caused by corrosion of piping, fittings, and vessels. In short, it combats Corrosion Under Insulation (CUI).
The extremely water – repellent nature of Temperlite® insulation sectionals means that they retain their low thermal conductivity factor even when is water ingress into the system. Calcium silicate and rock wool on the other hand have very high water absorption factors resulting in a loss of their insulation properties and an increase in the operational cost of the plant.
Temperlite® has a low thermal conductivity. Its superior moisture resistance helps keep water out of insulation which assures that good thermal conductivity performance is maintained over the long term.
Perlite sectional/board because of its sodium content provides corrosive inhibition towards chloride-induced stress corrosion cracking.
Perlite is not a trade name but a generic term for naturally occurring siliceous rock. To make perlite insulation, perlite ore is crushed and segregated. Then it is heated to a point in its softening range where its volume expands some 4 to 25 times due to the 2 – 6 % combined water in the ore. When rapidly heated to above 870°C (1600°F), the ore pops as this water vapourizes, creating countless partial vacuum air pockets in the heat softened glassy particles which makes expanded perlite lightweight and an excellent insulator. Expanded perlite can be manufactured to weigh as little as 32 kg/m³ (2 Ib/ft³), making it the ideal insulation for cryogenic tanks and cold boxes. In construction applications, perlite aggregates for plaster and lightweight insulating concrete have density ranges from 96 – 192 kg/m³ (6 – 12 Ib/ft³), in compliance with ASTM standards. A form of natural glass, perlite is chemically inert, with a pH of about 7. Highly resistant to heat and flame, expanded perlite is used world-wide as an efficient insulator and fire–proofing aid.
