Listed below is technical information on materials that are used for insulation
Cross-linked polyolefin foam:
The firm cross-linked foam structure in a cross-linked polyolefin foam allows for excellent compression resistance. Polyolefin foam is also resistant to fungi and UV. The minimum service temperature for this material is -80°C and maximum is +100° C. Some general applications for cross-linked polyolefin foam include cold, chilled and hot water systems, steam condensate, refrigeration, glycol, and brines.
Polyethylene insulation is widely used to prevent the freezing of domestic water supply times and to reduce heat loss from domestic heating pipes and air conditioning systems. The minimum service temperature is -70°C and the maximum is +95° C. Some general applications of polyethylene include cold, chilled and hot water systems, air conditioning, and refrigeration.
Mineral wool insulation can operate at high temperatures and may exhibit good fire performance ratings when tested. Mineral wool is used on all types of pipework, particularly industrial pipework operating at higher temperatures. The minimum service temperature is -68°C and maximum is +649° C. Some general applications of mineral wool include hot water systems, steam, steam condensate, steam turbines, breeching, stacks, and exhausts.
Glass wool insulation can be used for thermal and acoustic applications. The minimum service temperature is 0°C and the maximum is +340° C. Some general applications of glass wool include hot water systems, steam, steam condensate, and steam turbines.
Calcium silicate is used to insulate high-temperature pipes and equipment and for fire endurance applications as it is non-combustible. The minimum service temperature is 0°C and the maximum is
+650° C. Some general applications of calcium silicate include industrial facilities, such as: chemical plants, refineries, and steam electric power plants.
Ceramic fiber insulation is resistant against ultra-high temperatures and is fireproof. The minimum service temperature is 0°C and the maximum is +1,260° C. Ceramic fiber is mainly used as a high temperature insulator in power plants, steel-making plants and plants manufacturing chemical products.
Closed cell foam insulation:
Closed cell foam insulation is made from nitrile rubber, with high water vapour diffusion resistance and low thermal conductivity. The minimum service temperature is -50°C and the maximum is +105° C. Some general applications include air conditioning, heating and refrigeration systems.
