Fyrewrap EZ 1.5 Duct Insulation- Single Layer System Fyrewrap EZ 1.5 Duct Insulation- Single Layer System is a new optimized single-layer flexible enclosure for 1 and 2 hour fire-rated kitchen exhaust ducts and chemical fume ducts.
Excelfrax 200 VIP Insulation Unifrax Corporation′s Excelfrax® product line, based on advanced microporous insulation technology, is a family of products which all exhibit superior insulating characteristics. Excelfrax microporous insulation is composed of inorganic oxides, primarily turned silica Silicates and opacifiers are added to improve the material performance.
Microporous materials are very efficient insulation products These products actually have thermal conductivity values lower than still air. This performance is based on the ability of microporous insulation to block the three modes of heat transfer (i.e. conduction, convection, and radiation).
Excelfrax® 200 VIP is a Vacuum Insulation Panel (VIP) designed to provide superior insulation at temperatures between -20°F and +190° F. This advanced thermal insulation provides extremely low thermal conductivity by drastically reducing the heat transfer due to convection and conduction. The graph on page 2 details the thermal conductivity of Excelfrax 200 VIP.
Excelfrax 200 VIP uses a similar mechanism as a thermos bottle to achieve low thermal conductivity. In a thermos bottle, the double cavity walls are completely evacuated, which leaves virtually no gas available for heat transfer due to convection or conduction.
Welded in polyethylene (PE) film under vacuum, the exceptionally low thermal conductivity values of Excelfrax 200 VIP are due to extremely low inner pressure. Its superior insulating value provides equipment designers and users with significant advantages, such as :
Design flexibility by reducing insulation space requirements in appliances
Increased volume in commercial and domestic refrigerators
Reduction in package size and weight of insulated shipping containers
Increased volume for cargo in insulated snipping containers
Allows for longer shipping times/distances for temperature-controlled transportation systems
Excelfrax Microsporous Insulation 1800 Flexliner Unifrax Corporation′s Excelfrax® product line, based on advanced microporous insulation technology, is a family of products which all exhibit superior insulating characteristics. Excelfrax microporous insulation is composed of inorganic oxides, primarily fumed silica Silicates and opacifiers are added to improve the material performance.
Microporous materials are very efficient insulation products. These products actually have thermal conductivity values lower than still air. This performance is based on the ability of microporous insulation to block the three modes of heat transfer (i.e.. conduction, convection, and radiation).
Excelfrax 1800 Flexliner is a flexible, thin, microporous insulating panel with superior insulating characteristics. Excelfrax 1800 Flexliner is designed for use between the ladle shell and backup lining. This product can be used to provide maximum thermal efficiency in ladle liner design. By incorporating Excelfrax 1800 Flexliner into a lining design, it is possible to:
Reduce ladle heat loss without decreasing ladle capacity
Increase ladle capacity by reducing required thickness of insulating materials
Minimize the amount of solidified metal in the ladle after the casting process is complete
Typical applications for Excelfrax 1800 Flexliner are listed below:
