Unifrax Excelfrax® 200 VIP Vacuum Insulation Panel
Categories:	Ceramic; Oxide; Silicon Oxide
Material Notes:	Excelfrax® 200 VIP is a Vaccum Insulation Panel (VIP) designed to provide insulation at temperatures between -300°F and +300°F. This thermal insulation provides extremely low thermal conductivity by reducing the heat transfer due to convection and conduction. Welded in polyethylene (PE) film under vacuum, the low thermal conductivity values of Excelfrax 200 VIP are due to low inner pressure. Its insulating value provides equipment designers and users with 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 shipping containers, and allows for longer shipping times/distances for temperature-controlled transportation systems. Typical Applications Residential and industrial refrigerators Insulated packaging/shipping containers Refrigerated trucks/transportation systems Marine/Recreational Vehicle refrigerators Vending machines Cold storage units Information Provided by Unifrax I LLC
